* glusterd: Free up svc->conn on volume deleteAtin Mukherjee2017-12-071-0/+4
| | | | | | | | | | | | Daemons like snapd, tierd and gfproxyd are maintained on per volume basis and on a volume delete we should destroy the rpc connection established for them. >mainline patch : https://review.gluster.org/#/c/18957 Change-Id: Id1440e39da07b990fdb9b207df18da04b1ca8014 BUG: 1523050 Signed-off-by: Atin Mukherjee <amukherj@redhat.com>
* glusterd: persist brickinfo's port change into glusterd's storeGaurav Yadav2017-10-311-0/+19
| | | | | | | | | | | | | | | | | | Problem: Consider a case where node reboot is performed and prior to reboot brick was listening to 49153. Post reboot glusterd assigned 49152 to brick and started the brick process but the new port was never persisted. Now when glusterd restarts glusterd always read the port from its persisted store i.e 49153 however pmap signin happens with the correct port i.e 49152. Fix: Make sure when glusterd_brick_start is called, glusterd_store_volinfo is eventually invoked.

* glusterd: Gluster should keep PID file in correct locationGaurav Kumar Garg2017-10-251-8/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently Gluster keeps process pid information of all the daemons and brick processes in Gluster configuration file directory (ie., /var/lib/glusterd/*). These pid files should be seperate from configuration files. Deletion of the configuration file directory might result into serious problems. Also, /var/run/gluster is the default placeholder directory for pid files. So, with this fix Gluster will keep all process pid information of all processes in /var/run/gluster/* directory. > Change-Id: Idb09e3fccb6a7355fbac1df31082637c8d7ab5b4 > BUG: 1258561 > Signed-off-by: Gaurav Kumar Garg <ggarg@redhat.com> > Signed-off-by: Saravanakumar Arumugam <sarumuga@redhat.com> > Reviewed-on: https://review.gluster.org/13580 > Tested-by: MOHIT AGRAWAL <moagrawa@redhat.com> > Smoke: Gluster Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Atin Mukherjee <amukherj@redhat.com> > (Cherry pick from commit 220d406ad13d840e950eef001a2b36f87570058d) BUG: 1491059 Change-Id: Idb09e3fccb6a7355fbac1df31082637c8d7ab5b4 Signed-off-by: Mohit Agrawal <moagrawa@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: glusterd fails to start on nodes where glusterd tries to come up even before network is up.

* glusterd: Eliminate race in brick compatibility checking stageSamikshan Bairagya2017-05-311-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In https://review.gluster.org/17307/, while looking for compatible bricks for multiplexing, it is checked if the brick pidfile exists before checking if the corresponding brick process is running. However checking if the brick process is running just after checking if the pidfile exists isn't enough since there might be race conditions where the pidfile has been created but hasn't been updated with a pid value yet. This commit solves that by making sure that we wait iteratively till the pid value is updated as well. > Reviewed-on: https://review.gluster.org/17375 > Smoke: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Atin Mukherjee <amukherj@redhat.com> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> (cherry picked from commit a8624b8b13a1f4222e4d3e33fa5836d7b45369bc) Change-Id: Ib7a158f95566486f7c1f84b6357c9b89e4c797ae BUG: 1453087 Signed-off-by: Samikshan Bairagya <samikshan@gmail.com> Reviewed-on: https://review.gluster.org/17425 NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Tested-by: Raghavendra Talur <rtalur@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Raghavendra Talur <rtalur@redhat.com>
* glusterd: Don't spawn new glusterfsds on node reboot with brick-muxSamikshan Bairagya2017-05-301-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With brick multiplexing enabled, upon a node reboot new bricks were not being attached to the first spawned brick process even though there wasn't any compatibility issues. The reason for this is that upon glusterd restart after a node reboot, since brick services aren't running, glusterd starts the bricks in a "no-wait" mode. So after a brick process is spawned for the first brick, there isn't enough time for the corresponding pid file to get populated with a value before the compatibilty check is made for the next brick. This commit solves this by iteratively waiting for the pidfile to be populated in the brick compatibility comparison stage before checking if the brick process is alive. > Reviewed-on: https://review.gluster.org/17307 > Reviewed-by: Atin Mukherjee <amukherj@redhat.com> > Smoke: Gluster Build System <jenkins@build.gluster.org> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> (cherry picked from commit 13e7b3b354a252ad4065f7b2f0f805c40a3c5d18) Change-Id: Ibd1f8e54c63e4bb04162143c9d70f09918a44aa4 BUG: 1453087 Signed-off-by: Samikshan Bairagya <samikshan@gmail.com> Reviewed-on: https://review.gluster.org/17352 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Atin Mukherjee <amukherj@redhat.com> Reviewed-by: Raghavendra Talur <rtalur@redhat.com>
* Fixes quota aux mount failureSanoj Unnikrishnan2017-05-131-10/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The aux mount is created on the first limit/remove_limit/list command and it remains until volume is stopped / deleted / (quota is disabled) , where we do a lazy unmount. If the process is uncleanly terminated, then the mount entry remains and we get (Transport disconnected) error on subsequent attempts to run quota list/limit-usage/remove commands. Second issue, There is also a risk of inadvertent rm -rf on the /var/run/gluster causing data loss for the user. Ideally, /var/run is a temp path for application use and should not cause any data loss to persistent storage. Solution: 1) unmount the aux mount after each use. 2) clean stale mount before mounting, if any. One caveat with doing mount/unmount on each command is that we cannot use same mount point for both list and limit commands. The reason for this is that list command needs mount to be accessible in cli after response from glusterd, So it could be unmounted by a limit command if executed in parallel (had we used same mount point) Hence we use separate mount points for list and limit commands. > Reviewed-on: https://review.gluster.org/16938 > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > Smoke: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Manikandan Selvaganesh <manikandancs333@gmail.com> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Raghavendra G <rgowdapp@redhat.com> > Reviewed-by: Atin Mukherjee <amukherj@redhat.com> > (cherry picked from commit 2ae4b4058691b324535d802f4e6d24cce89a10e5) Change-Id: I4f9e39da2ac2b65941399bffb6440db8a6ba59d0 BUG: 1449779 Signed-off-by: Sanoj Unnikrishnan <sunnikri@redhat.com> Reviewed-on: https://review.gluster.org/17241 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Raghavendra Talur <rtalur@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Reset brick currently kills of the corresponding brick process. However, with brick multiplexing enabled, stopping the brick process would render all bricks attached to it unavailable. To handle this correctly, we need to make sure that the brick process is terminated only if brick-multiplexing is disabled. Otherwise, we should send the GLUSTERD_BRICK_TERMINATE rpc to the respective brick process to detach the brick that is to be reset. > Signed-off-by: Samikshan Bairagya <samikshan@gmail.com> > Reviewed-on: https://review.gluster.org/17128 > Smoke: Gluster Build System <jenkins@build.gluster.org> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Atin Mukherjee <amukherj@redhat.com> (cherry picked from commit 74383e3ec6f8244b3de9bf14016452498c1ddcf0) Change-Id: I69002d66ffe6ec36ef48af09b66c522c6d35ac58 BUG: 1449934 Signed-off-by: Samikshan Bairagya <samikshan@gmail.com> Reviewed-on: https://review.gluster.org/17253 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Atin Mukherjee <amukherj@redhat.com>

* glusterd: socketfile & pidfile related fixes for brick multiplexing featureMohit Agrawal2017-05-101-25/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: While brick-muliplexing is on after restarting glusterd, CLI is not showing pid of all brick processes in all volumes. Solution: While brick-mux is on all local brick process communicated through one UNIX socket but as per current code (glusterd_brick_start) it is trying to communicate with separate UNIX socket for each volume which is populated based on brick-name and vol-name.Because of multiplexing design only one UNIX socket is opened so it is throwing poller error and not able to fetch correct status of brick process through cli process. To resolve the problem write a new function glusterd_set_socket_filepath_for_mux that will call by glusterd_brick_start to validate about the existence of socketpath. To avoid the continuous EPOLLERR erros in logs update socket_connect code.

* glusterd/geo-rep: Fix snapshot create in geo-rep setupKotresh HR2017-05-021-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glusterd persists geo-rep sessions in glusterd info file which is represented by dictionary 'volinfo->gsync_slaves' in memory. Glusterd also maintains in memory active geo-rep sessions in dictionary 'volinfo->gsync_active_slaves' whose key is "<slave_url>::<slavhost>". When glusterd is restarted while the geo-rep sessions are active, it builds the 'volinfo->gsync_active_slaves' from persisted glusterd info file. Since slave volume uuid is added to "voinfo->gsync_slaves" with the commit "http://review.gluster.org/13111", it builds it with key "<slave_url>::<slavehost>:<slavevol_uuid>" which is wrong. So during snapshot pre-validation which checks whether geo-rep is active or not, it always says it is ACTIVE, as geo-rep stop would not deleted this key.

* glusterd: don't queue attach reqs before connectingJeff Darcy2017-03-101-11/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was causing USS tests to fail. The underlying problem here is that if we try to queue the attach request too soon after starting a brick process then the socket code will get an error trying to write to the still-unconnected socket. Its response is to shut down the socket, which causes the queued attach requests to be force-unwound. There's nothing to retry them, so they effectively never happen and those bricks (second and succeeding for a snapshot) never become available. We *do* have a retry loop for attach requests, but currently break out as soon as a request is queued - not actually sent. The fix is to modify that loop so it will wait some more if the rpc connection isn't even complete yet. Now we break out only when we have a completed connection *and* a queued request.

* glusterd: add a cli command to trigger a statedump on a clientPoornima G2017-02-131-0/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this, we will be able to trigger statedumps on remote Gluster clients, mainly targetted for applications using libgfapi. Design: SIGUSR signal is the most comman way of taking a statedump in Gluster. But it cannot be used for libgfapi based processes, as the process loading the library might have already consumed SIGUSR signal. Hence going by the command way. One has to issue a Gluster command to initiate a statedump on the libgfapi based client. The command takes hostname and PID as an argument. All the glusterds in the cluster, check if they are connected to the specified hostname, and send an RPC request to all the connected clients from that hostname (via the mgmt connection). > URL: http://review.gluster.org/16357 > BUG: 1169302 > Signed-off-by: Poornima G <pgurusid@redhat.com> > [ndevos: minor fixes and split patch in smaller pieces] > Reviewed-on-master: https://review.gluster.org/9228 > Reviewed-by: Niels de Vos <ndevos@redhat.com> > Tested-by: Niels de Vos <ndevos@redhat.com> > Reviewed-by: Kaleb KEITHLEY <kkeithle@redhat.com> > Reviewed-by: Samikshan Bairagya <samikshan@gmail.com> BUG: 1418981 Change-Id: Icbe4d2f026b32a2c7d5535e1bfb2cdaaff042e91 Signed-off-by: Shyam <srangana@redhat.com> Reviewed-on: https://review.gluster.org/16601 Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Niels de Vos <ndevos@redhat.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org>
* glusterd: keep snapshot bricks separate from regular onesJeff Darcy2017-02-101-82/+124
| | | | | | | | | | | | | | | | | | | | | | | | | | | The problem here is that a volume's transport options can change, but any snapshots' bricks don't follow along even though they're now incompatible (with respect to multiplexing). This was causing the USS+SSL test to fail. By keeping the snapshot bricks separate (though still potentially multiplexed with other snapshot bricks including those for other volumes) we can ensure that they remain unaffected by changes to their parent volumes. Also fixed various issues with how the test waits (or more precisely didn't) for various events to complete before it continues.

* core: run many bricks within one glusterfsd processJeff Darcy2017-02-011-51/+562
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for multiple brick translator stacks running in a single brick server process. This reduces our per-brick memory usage by approximately 3x, and our appetite for TCP ports even more. It also creates potential to avoid process/thread thrashing, and to improve QoS by scheduling more carefully across the bricks, but realizing that potential will require further work. Multiplexing is controlled by the "cluster.brick-multiplex" global option. By default it's off, and bricks are started in separate processes as before. If multiplexing is enabled, then *compatible* bricks (mostly those with the same transport options) will be started in the same process.

The commands affected: 1) Attach tier will trigger this process instead of old one 2) tier start and tier start force will also trigger this process. 3) volume status [tier] will show tier daemon as a process instead of task and normal tier status and tier detach status works. 4) tier stop implemented. 5) detach tier implemented separately along with new detach tier status 6) volume tier volname status will work using the changes. 7) volume set works This patch has separated the tier translator from the legacy DHT rebalance code. It now sends the RPCs from the CLI to glusterd separate to the DHT rebalance code. The daemon is now a service, similar to the snapshot daemon, and can be viewed using the volume status command. The code for the validation and commit phase are the same as the earlier tier validation code in DHT rebalance. The “brickop” phase has been changed so that the status command can use this framework. The service management framework is now used. DHT rebalance does not use this framework. This service framework takes care of : *) spawning the daemon, killing it and other such processes. *) volume set options , which are written on the volfile. *) restart and reconfigure functions. Restart is to restart the daemon at two points 1)after gluster goes down and comes up. 2) to stop detach tier. *) reconfigure is used to make immediate volfile changes. By doing this, we don’t restart the daemon. it has the code to rewrite the volfile for topological changes too (which comes into place during add and remove brick). With this patch the log, pid, and volfile are separated and put into respective directories.

Usage: # gluster volume get all cluster.max-op-version Example output: Option Value ------ ----- cluster.max-op-version 30900 NOTE: The only way to test this feature for now is to set the GD_OP_VERSION_MAX macro to different values (30800 for 3.8,30900 for 3.9, and so on) and rebuild glusterd. Since the regression test framework currently doesn't have support to simulate these tests, there are no accompanying regression tests for this feature. It should be possible to add tests once glusto comes in and makes it easier to run a heterogeneous cluster.

* glusterd : Introduce reset brickAnuradha Talur2016-08-291-3/+324
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The command basically allows replace brick with src and dst bricks as same. Usage: gluster v reset-brick <volname> <hostname:brick-path> start This command kills the brick to be reset. Once this command is run, admin can do other manual operations that they need to do, like configuring some options for the brick. Once this is done, resetting the brick can be continued with the following options. gluster v reset-brick <vname> <hostname:brick> <hostname:brick> commit {force} Does the job of resetting the brick. 'force' option should be used when the brick already contains volinfo id. Problem: On doing a disk-replacement of a brick in a replicate volume the following 2 scenarios may occur : a) there is a chance that reads are served from this replaced-disk brick, which leads to empty reads. b) potential data loss if next writes succeed only on replaced brick, and heal is done to other bricks from this one. Solution: After disk-replacement, make sure that reset-brick command is run for that brick so that pending markers are set for the brick and it is not chosen as source for reads and heal. But, as of now replace-brick for the same brick-path is not allowed. In order to fix the above mentioned problem, same brick-path replace-brick is needed. With this patch reset-brick commit {force} will be allowed even when source and destination <hostname:brickpath> are identical as long as 1) destination brick is not alive 2) source and destination brick have the same brick uuid and path. Also, the destination brick after replace-brick will use the same port as the source brick.

* glusterd/cli: cli to get local state representation from glusterdSamikshan Bairagya2016-08-261-0/+194
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently there is no existing CLI that can be used to get the local state representation of the cluster as maintained in glusterd in a readable as well as parseable format. The CLI added has the following usage: # gluster get-state [daemon] [odir <path/to/output/dir>] [file <filename>] This would dump data points that reflect the local state representation of the cluster as maintained in glusterd (no other daemons are supported as of now) to a file inside the specified output directory. The default output directory and filename is /var/run/gluster and glusterd_state_<timestamp> respectively. The option for specifying the daemon name leaves room to add support for other daemons in the future. Following are the data points captured as of now to represent the state from the local glusterd pov: * Peer: - Primary hostname - uuid - state - connection status - List of hostnames * Volumes: - name, id, transport type, status - counts: bricks, snap, subvol, stripe, arbiter, disperse, redundancy - snapd status - quorum status - tiering related information - rebalance status - replace bricks status - snapshots * Bricks: - Path, hostname (for all bricks these info will be shown) - port, rdma port, status, mount options, filesystem type and signed in status for bricks running locally. * Services: - name, online status for initialised services * Others: - Base port, last allocated port - op-version - MYUUID Change-Id: I4a45cc5407ab92d8afdbbd2098ece851f7e3d618 BUG: 1353156 Signed-off-by: Samikshan Bairagya <samikshan@gmail.com> Reviewed-on: http://review.gluster.org/14873 Reviewed-by: Avra Sengupta <asengupt@redhat.com> Smoke: Gluster Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Atin Mukherjee <amukherj@redhat.com>

* glusterd: Fix volume restart issue upon glusterd restartSamikshan Bairagya2016-08-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | http://review.gluster.org/#/c/14758/ introduces a check in glusterd_restart_bricks that makes sure that if server quorum is enabled and if the glusterd instance has been restarted, the bricks do not get started. This prevents bricks which have been brought down purposely, say for maintainence, from getting started upon a glusterd restart. However this change introduced regression for a situation that involves multiple volumes. The bricks from the first volume get started, but then for the subsequent volumes the bricks do not get started. This patch fixes that by setting the value of conf->restart_done to _gf_true only after bricks are started correctly for all volumes.

* glusterd: clean up old port and allocate new one on every restartAtin Mukherjee2016-08-031-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | GlusterD as of now was blindly assuming that the brick port which was already allocated would be available to be reused and that assumption is absolutely wrong. Solution : On first attempt, we thought GlusterD should check if the already allocated brick ports are free, if not allocate new port and pass it to the daemon. But with that approach there is a possibility that if PMAP_SIGNOUT is missed out, the stale port will be given back to the clients where connection will keep on failing. Now given the port allocation always start from base_port, if everytime a new port has to be allocated for the daemons, the port range will still be under control. So this fix tries to clean up old port using pmap_registry_remove () if any and then goes for pmap_registry_alloc () Change-Id: If54a055d01ab0cbc06589dc1191d8fc52eb2c84f BUG: 1221623 Signed-off-by: Atin Mukherjee <amukherj@redhat.com> Reviewed-on: http://review.gluster.org/15005 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Avra Sengupta <asengupt@redhat.com>
* changelog/rpc: Fix rpc_clnt_t mem leaksKotresh HR2016-07-221-0/+1

Well, it was not a necessity to free rpc-clnt object till now because all the existing use cases needs to reconnect back on disconnects. Hence timer code was not taking ref on rpc-clnt object. Glusterd had some use-cases that led to crash due to ping-timer and they fixed only those code paths that involve ping-timer. Now, since changelog has an use-case where rpc-clnt need to be freed up, we need to fix timer code to take refs 2. In changelog, because of issue 1, only mydata was being freed which is incorrect. And there are races where rpc-clnt object would access the freed mydata which would lead to crashes. Since changelog xlator resides on brick side and is long living process, if multiple libgfchangelog consumers register to changelog and disconnect/reconnect mulitple times, it would result in leak of 'rpc-clnt' object for every connect/disconnect. SOLUTION: 1. Handle ref/unref of 'rpc_clnt' structure in timer functions properly. 2. In changelog, unref 'rpc_clnt' in RPC_CLNT_DISCONNECT after disabling timers and free mydata on RPC_CLNT_DESTROY. RPC SETUP IN CHANGELOG: 1. changelog xlator initiates rpc server say 'changelog_rpc_server' 2. libgfchangelog initiates one rpc server say 'libgfchangelog_rpc_server' 3. libgfchangelog initiates rpc client and connects to 'changelog_rpc_server' 4. In return changelog_rpc_server initiates a rpc client and connects back to 'libgfchangelog_rpc_server' REF/UNREF HANDLING IN TIMER FUNCTIONS: Let's say rpc clnt refcount = 1 1. Take the ref before reigstering callback to timer queue >>>> rpc_clnt_ref (say ref count becomes = 2) 2. Register a callback to timer say 'callback1' 3. If register fails: >>>> rpc_clnt_unref (ref count = 1) 4. On timer expiration, 'callback1' gets called. So unref rpc clnt at the end in 'callback1'. This is corresponding to ref taken in step 1 >>>> rpc_clnt_unref (ref count = 1) 5. The cycle from step-1 to step-4 continues....until timer cancel event happens 6. timer cancel of say 'callback1' If timer cancel fails: Do nothing, Step-4 would have unrefd If timer cancel succeeds: >>>> rpc_clnt_unref (ref count = 1) Change-Id: I91389bc511b8b1a17824941970ee8d2c29a74a09 BUG: 1316178 Signed-off-by: Kotresh HR <khiremat@redhat.com> Reviewed-on: http://review.gluster.org/13658 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Raghavendra G <rgowdapp@redhat.com>

* glusterd: Fix gsyncd upgrade issueKotresh HR2016-07-131-28/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: gluster upgrade is not generating new volfiles Cause: During upgrade, "glusterd --xlator-option *.upgrade=on -N" is run to generate new volfiles. It is run post 'glusterfs' rpm installation. The above command fails during upgrade if geo-replication is installed. This is because on glusterd start 'gsyncd' binary is called to configure geo-replication related stuff. Since 'glusterfs' rpm is installed prior to 'geo-rep' rpm, the 'gsyncd' binary used to glusterd upgrade command is of old version and hence it fails before generating new volfiles. Solution: Don't call geo-replication configure during upgrade/downgrade. Geo-replication configuration happens during start of glusterd after upgrade.
