* glusterd: fix crash on statedump when no volumes are startedAtin Mukherjee2017-06-151-12/+17
| | | | | | | | | | | | | | | | | pmap object is created when glusterd allocates a port for the very first time, however before that if someone tries to take statedump glusterd will crash. Solution : Add a NULL check before accessing pmap reference.

* glusterd: fix quorum calculation if percentage is not specified correctlyMichael Adam2017-06-141-1/+0
| | | | | | | | | | | | | | | | | | | | | | | There was an extra "ratio = _gf_true". - In case the ratio was specified correctly in the volfile, this is redundant. - In case the ratio was specified, but not parseable into a precentage, this is wrong and would lead to a quorum count of 0 instead of falling back to the default of 50% + 1. This patch removes the extra setting of "ratio".

* nl-cache: Fix a possible crash and stale cachePoornima G2017-06-131-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue1: Consider the followinf sequence of operations: ... nlc_ctx = nlc_ctx_get (inode i1) ....... -> nlc_clear_cache (i1) gets called as a part of nlc_invalidate or any other callers ... GF_FREE (ii nlc_ctx) LOCK (nlc_ctx->lock); -> This will result in crash as the ctx got freed in nlc_clear_cache. Issue2: lookup on dir1/file1 result in ENOENT add cache to dir1 at time T1 .... CHILD_DOWN at T2 lookup on dir1/file2 result in ENOENT add cache to dir1, but the cache time is still T1 lookup on dir1/file2 - should have been served from cache but the cache time is T1 < T2, hence cache is considered as invalid. So, after CHILD_DOWN the right thing would be to clear the cache and restart caching on that inode. Solution: Do not free nlc_ctx in nlc_clear_cache, but only in inode_forget() The fix for both issue1 and 2 is interleaved hence sending it as single patch.

* protocol/server: make listen backlog value as configurableMohammed Rafi KC2017-06-084-7/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | problem: When we call listen from protocol/server, we are giving a hard coded valie of 10 if it is not manually given. With multiplexing, especially when glusterd restarts all clients may try to connect to the server at a time. Which will result in overflowing the queue, and kernel will complain about the errors. Solution: This patch will introduce a volume set command to make backlog value as a configurable. This patch also changes the default values for backlog from 10 to 128. This changes is only applicable for sockets listening from protocol. Example: gluster volume set <volname> transport.listen-backlog 1024 Note: 1 Brick has to be restarted to get this value in effect 2 This changes won't be reflected in glusterd, or other xlators which calls listen. If you need, you have to add this option to the volfile.

* glusterd: fix brick start raceAtin Mukherjee2017-06-065-21/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit tries to handle a race where we might end up trying to spawn the brick process twice with two different set of ports resulting into glusterd portmapper having the same brick entry in two different ports which will result into clients to fail connect to bricks because of incorrect ports been communicated back by glusterd. In glusterd_brick_start () checking brickinfo->status flag to identify whether a brick has been started by glusterd or not is not sufficient as there might be cases where while glusterd restarts glusterd_restart_bricks () will be called through glusterd_spawn_daemons () in synctask and immediately glusterd_do_volume_quorum_action () with server-side-quorum set to on will again try to start the brick and in case if the RPC_CLNT_CONNECT event for the same brick hasn't been processed by glusterd by that time, brickinfo->status will still be marked as GF_BRICK_STOPPED resulting into a reattempt to start the brick with a different port and that would result portmap go for a toss and resulting clients to fetch incorrect port. Fix would be to introduce another enum value called GF_BRICK_STARTING in brickinfo->status which will be set when a brick start is attempted by glusterd and will be set to started through RPC_CLNT_CONNECT event. For brick multiplexing, on attach brick request given the brickinfo->status flag is marked to started directly this value will not have any effect. Also this patch removes started_here flag as it looks to be redundant as brickinfo->status.

* glusterd: Fix regression wrt add-brick on replica count changeSamikshan Bairagya2017-06-012-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | tests/bugs/glusterd/bug-1406411-fail-add-brick-on-replica-count-change.t was failing on centos machines with brick multiplexing enabled. This is because detaching individual bricks manually from the backend like it is done in the regression test framework by 'kill_brick', fails to send a RPC_CLNT_DISCONNECT to glusterd when multiplexing is enabled. This causes the add-brick command to not fail when one of the bricks are killed using kill_brick in the regression test framework. To fix this, set the brick status to GF_BRICK_STOPPED on the glusterd end during portmap signout. This commit also sets the brick status in glusterd_brick_stop() function so that the brick status is correctly set to 'stopped' even when the function is called independently for individual bricks.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | stopped any volume Problem: After enabled brick mux if any volume has down and then try ot run mount with running volume , mount command is hung. Solution: After enable brick mux server has shared one data structure server_conf for all associated subvolumes.After down any subvolume in some ungraceful manner (remove brick directory) posix xlator sends GF_EVENT_CHILD_DOWN event to parent xlatros and server notify updates the child_up to false in server_conf.When client is trying to communicate with server through mount it checks conf->child_up and it is FALSE so it throws message "translator are not yet ready". From this patch updated structure server_conf to save child_up status for xlator wise. Another improtant correction from this patch is cleanup threads from server side xlators after stop the volume.

| | | | | | | | | | | | | | | | | | | | | | 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.

* rda, glusterd: Change the max of rda-cache-limit to INFINITYPoornima G2017-05-211-0/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: The max value of rda-cache-limit is 1GB before this patch. When parallel-readdir is enabled, there will be many instances of readdir-ahead, hence the rda-cache-limit depends on the number of instances. Eg: On a volume with distribute count 4, rda-cache-limit when parallel-readdir is enabled, will be 4GB instead of 1GB. Consider a followinf sequence of operations: - Enable parallel readdir - Set rda-cache-limit to lets say 3GB - Disable parallel-readdir, this results in one instance of readdir-ahead and the rda-cache-limit will be back to 1GB, but the current value is 3GB and hence the mount will stop working as 3GB > max 1GB. Solution: To fix this, we can limit the cache to 1GB even when parallel-readdir is enabled. But there is no necessity to limit the cache to 1GB, it can be increased if the system has enough resources. Hence getting rid of the rda-cache-limit max value is more apt. If we just change the rda-cache-limit max to INFINITY, we will render older(<3.11) clients broken, when the rda-cache-limit is set to > 1GB (as the older clients still expect a value < 1GB). To safely change the max value of rda-cache-limit to INFINITY, add a check in glusted to verify all the clients are > 3.11 if the value exceeds 1GB.

* glusterd: Don't spawn new glusterfsds on node reboot with brick-muxSamikshan Bairagya2017-05-183-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fixes quota aux mount failureSanoj Unnikrishnan2017-05-084-60/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Halo Replication feature for AFR translatorKevin Vigor2017-05-023-2/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Halo Geo-replication is a feature which allows Gluster or NFS clients to write locally to their region (as defined by a latency "halo" or threshold if you like), and have their writes asynchronously propagate from their origin to the rest of the cluster. Clients can also write synchronously to the cluster simply by specifying a halo-latency which is very large (e.g. 10seconds) which will include all bricks. In other words, it allows clients to decide at mount time if they desire synchronous or asynchronous IO into a cluster and the cluster can support both of these modes to any number of clients simultaneously. There are a few new volume options due to this feature: halo-shd-latency: The threshold below which self-heal daemons will consider children (bricks) connected. halo-nfsd-latency: The threshold below which NFS daemons will consider children (bricks) connected. halo-latency: The threshold below which all other clients will consider children (bricks) connected. halo-min-replicas: The minimum number of replicas which are to be enforced regardless of latency specified in the above 3 options. If the number of children falls below this threshold the next best (chosen by latency) shall be swapped in. New FUSE mount options: halo-latency & halo-min-replicas: As descripted above. This feature combined with multi-threaded SHD support (D1271745) results in some pretty cool geo-replication possibilities. Operational Notes: - Global consistency is gaurenteed for synchronous clients, this is provided by the existing entry-locking mechanism. - Asynchronous clients on the other hand and merely consistent to their region. Writes & deletes will be protected via entry-locks as usual preventing concurrent writes into files which are undergoing replication. Read operations on the other hand should never block. - Writes are allowed from _any_ region and propagated from the origin to all other regions. The take away from this is care should be taken to ensure multiple writers do not write the same files resulting in a gfid split-brain which will require resolution via split-brain policies (majority, mtime & size). Recommended method for preventing this is using the nfs-auth feature to define which region for each share has RW permissions, tiers not in the origin region should have RO perms. TODO: - Synchronous clients (including the SHD) should choose clients from their own region as preferred sources for reads. Most of the plumbing is in place for this via the child_latency array. - Better GFID split brain handling & better dent type split brain handling (i.e. create a trash can and move the offending files into it). - Tagging in addition to latency as a means of defining which children you wish to synchronously write to Test Plan: - The usual suspects, clang, gcc w/ address sanitizer & valgrind - Prove tests Reviewers: jackl, dph, cjh, meyering Reviewed By: meyering Subscribers: ethanr Differential Revision: https://phabricator.fb.com/D1272053 Tasks: 4117827 Change-Id: I694a9ab429722da538da171ec528406e77b5e6d1 BUG: 1428061 Signed-off-by: Kevin Vigor <kvigor@fb.com> Reviewed-on: http://review.gluster.org/16099 Reviewed-on: https://review.gluster.org/16177 Tested-by: Pranith Kumar Karampuri <pkarampu@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> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current rebalance throttle options: lazy/normal/aggressive may not always be sufficient for the purpose of throttling. In our recent test, we observed for certain setups, normal and aggressive modes behaved similarly consuming full disk bandwidth. So in cases like this admin should be able to tune it down(or vice versa) depending on the need. Along with old throttle configurations, thread counts are tuned based on number. e.g. gluster v set vol-name cluster-rebal.throttle 5. Admin can tune up/down between 0 and the number of cores available. Note: For heterogenous servers, validation will fail on the old server if "number" is given for throttle configuration. The message looks something like this: "volume set: failed: Staging failed on vm2.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Fixed the same in this patch.

* dht: Add readdir-ahead in rebalance graph if parallel-readdir is onPoornima G2017-04-182-5/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: The value of linkto xattr is generally the name of the dht's next subvol, this requires that the next subvol of dht is not changed for the life time of the volume. But with parallel readdir enabled, the readdir-ahead loaded below dht, is optional. The linkto xattr for first subvol, when: - parallel readdir is enabled : "<volname>-readdir-head-0" - plain distribute volume : "<volname>-client-0" - distribute replicate volume : "<volname>-afr-0" The value of linkto xattr is "<volname>-readdir-head-0" when parallel readdir is enabled, and is "<volname>-client-0" if its disabled. But the dht_lookup takes care of healing if it cannot identify which linkto subvol, the xattr points to. In dht_lookup_cbk, if linkto xattr is found to be "<volname>-client-0" and parallel readdir is enabled, then it cannot understand the value "<volname>-client-0" as it expects "<volname>-readdir-head-0". In that case, dht_lookup_everywhere is issued and then the linkto file is unlinked and recreated with the right linkto xattr. The issue is when parallel readdir is enabled, mount point accesses the file that is currently being migrated. Since rebalance process doesn't have parallel-readdir feature, it expects "<volname>-client-0" where as mount expects "<volname>-readdir-head-0". Thus at some point either the mount or rebalance will fail. Solution: Enable parallel-readdir for rebalance as well and then do not allow enabling/disabling parallel-readdir if rebalance is in progress.

Since getting the client details involves sending RPC requests to the respective local bricks, this is a relatively more costly operation. These client details would be added to the get-state output only if the get-state command is invoked with the 'detail' option. This commit therefore also changes the get-state CLI usage. The modified usage is as follows: # gluster get-state [<daemon>] [[odir </path/to/output/dir/>] \ [file <filename>]] [detail] Change-Id: I42cd4ef160f9e96d55a08a10d32c8ba44e4cd3d8 BUG: 1431183 Signed-off-by: Samikshan Bairagya <samikshan@gmail.com> Reviewed-on: https://review.gluster.org/17003 NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Smoke: Gluster Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Atin Mukherjee <amukherj@redhat.com>
* rpc: add options to manage socket keepalive lifespanMilind Changire2017-04-121-1/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Default values for handling socket timeouts for brick responses are insufficient for aggressive applications such as databases. Solution: Add 1:1 gluster options for keepalive, keepalive-idle, keepalive-interval and keepalive-timeout as per the socket level options available as per tcp(7) man page. Default values for options are NOT agressive and continue to be values which result in default timeout when only the keep alive option is turned on. These options are Linux specific and will not be applicable to the *BSDs.

* xlator: do not call dlclose() when debuggingNiels de Vos2017-04-077-11/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Valgrind can not show the symbols if a .so after calling dlclose(). The unhelpful ??? in the output gets resolved properly with this change: ==25170== 344 bytes in 1 blocks are definitely lost in loss record 233 of 324 ==25170== at 0x4C29975: calloc (vg_replace_malloc.c:711) ==25170== by 0x52C7C0B: __gf_calloc (mem-pool.c:117) ==25170== by 0x12B0638A: ??? ==25170== by 0x528FCE6: __xlator_init (xlator.c:472) ==25170== by 0x528FE16: xlator_init (xlator.c:498) ==25170== by 0x52DA8D6: glusterfs_graph_init (graph.c:321) ==25170== by 0x52DB587: glusterfs_graph_activate (graph.c:695) ==25170== by 0x5046407: glfs_process_volfp (glfs-mgmt.c:79) ==25170== by 0x5043B9E: glfs_volumes_init (glfs.c:281) ==25170== by 0x5044FEC: glfs_init_common (glfs.c:986) ==25170== by 0x50451A7: glfs_init@@GFAPI_3.4.0 (glfs.c:1031) By not calling dlclose(), the dynamically loaded .so is still available upon program exit, and Valgrind is able to resolve the symbols. This will add an additional leak, so dlclose() is called for normal builds, but skipped when configuring with "./configure --enable-valgrind" or passing the "run-with-valgrind" xlator option.
