* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-051-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | libglusterfs devel package headers are referenced in code using include semantics for a program, this while it works can be better especially when dealing with out of tree xlator builds or in general out of tree devel package usage. Towards this, the following changes are done, - moved all devel headers under a glusterfs directory - Included these headers using system header notation <> in all code outside of libglusterfs - Included these headers using own program notation "" within libglusterfs This change although big, is just moving around the headers and making it correct when including these headers from other sources. This helps us correctly include libglusterfs includes without namespace conflicts.

* glusterd: glusterd to regenerate volfiles when GD_OP_VERSION_MAX changesAtin Mukherjee2018-12-051-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While glusterd has an infra to allow post install of spec to bring it up in the interim upgrade mode to allow all the volfiles to be regenerated with the latest executable, in container world the same methodology is not followed as container image always point to the specific gluster rpm and gluster rpm doesn't go through an upgrade process. This fix does the following: 1. If glusterd.upgrade file doesn't exist, regenerate the volfiles 2. If maximum-operating-version read from glusterd.upgrade doesn't match with GD_OP_VERSION_MAX, glusterd detects it to be a version where new options are introduced and regenerate the volfiles. Tests done: 1. Bring up glusterd, check if glusterd.upgrade file has been created with GD_OP_VERSION_MAX value. 2. Post 1, restart glusterd and check glusterd hasn't regenerated the volfiles as there's is no change in the GD_OP_VERSION_MAX vs the op_version read from the file. 3. Bump up the GD_OP_VERSION_MAX in the code by 1 and post compilation restart glusterd where the volfiles should be again regenerated. Note: The old way of having volfiles regenerated during an rpm upgrade is kept as it is for now but eventually this can be sunset later.

* glusterd: perform rcu_read_lock/unlock() under cleanup_lock mutexSanju Rakonde2018-12-031-2/+16
| | | | | | | | | | | | | | Problem: glusterd should not try to acquire locks on any resources, when it already received a SIGTERM and cleanup is started. Otherwise we might hit segfault, since the thread which is going through cleanup path will be freeing up the resouces and some other thread might be trying to acquire locks on freed resources. Solution: perform rcu_read_lock/unlock() under cleanup_lock mutex. fixes: bz#1654270 Change-Id: I87a97cfe4f272f74f246d688660934638911ce54 Signed-off-by: Sanju Rakonde <srakonde@redhat.com>

* glusterd: acquire lock to update volinfo structureSanju Rakonde2018-09-181-3/+6
| | | | | | | | | | | | | | | | | | Problem: With commit cb0339f92, we are using a separate syntask for restart_bricks. There can be a situation where two threads are accessing the same volinfo structure at the same time and updating volinfo structure. This can lead volinfo to have inconsistent values and assertion failures because of unexpected values. Solution: While updating the volinfo structure, acquire a store_volinfo_lock, and release the lock only when the thread completed its critical section part.

* glusterd: ignore importing volume which is undergoing a delete operationAtin Mukherjee2018-08-161-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem explanation: Assuming in a 3 nodes cluster, if N1 originates a delete operation and while N1's commit phase completes, either glusterd service of N2 or N3 gets disconnected from N1 (before completing the commit phase), N1 will attempt to end up importing the volume which is in-flight for a delete in other nodes as a fresh resulting into an incorrect configuration state. Fix: Mark a volume as stage deleted once a volume delete operation passes it's staging phase and reset this flag during unlock phase. Now during this intermediate phase if the same volume gets imported to other peers, it shouldn't considered to be recreated. An automated .t is quite tough to implement with the current infra. Test Case: 1. Keep creating and deleting volumes in a loop on a 3 node cluster 2. Simulate n/w failure between the peers (ifdown followed by ifup) 3. Check if output of 'gluster v list | wc -l' is same across all 3 nodes during 1 & 2.

* glusterd: compare friend data within mutexAtin Mukherjee2018-08-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | During friend handshake if the glusterd receives more than one friend updates, it might very well become possible that two threads would end up working on two different volinfo references and glusterd might end up updating the store with a old volinfo reference. While debugging glusterd crash from validating-server-quorum.t test file from the line-coverage regression the same was observed. Solution is to run glusterd_compare_friend_data under a mutex. Test: As the crash was more visible in the line-coverage run (given lcov does some instrumentation and exposes the races), 6 manual lcov runs were triggered starting from https://build.gluster.org/job/line-coverage/443 to https://build.gluster.org/job/line-coverage/449/ and no crash was observed from validating-server-quorum.t Change-Id: I86fce473a76fd24742d51bf17a685d28b90a8941 Fixes: bz#1603063 Signed-off-by: Atin Mukherjee <amukherj@redhat.com>

* glusterd: import volumes in separate synctaskAtin Mukherjee2018-02-091-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | With brick multiplexing, to attach a brick to an existing brick process the prerequisite is to have the compatible brick to finish it's initialization and portmap sign in and hence the thread might have to go to a sleep and context switch the synctask to allow the brick process to communicate with glusterd. In normal code path, this works fine as glusterd_restart_bricks () is launched through a separate synctask. In case there's a mismatch of the volume when glusterd restarts, glusterd_import_friend_volume is invoked and then it tries to call glusterd_start_bricks () from the main thread which eventually may land into the similar situation. Now since this is not done through a separate synctask, the 1st brick will never be able to get its turn to finish all of its handshaking and as a consequence to it, all the bricks will fail to get attached to it. Solution : Execute import volume and glusterd restart bricks in separate synctask. Importing snaps had to be also done through synctask as there's a dependency of the parent volume need to be available for the importing snap functionality to work.

* glusterd: fix brick restart parallelismAtin Mukherjee2017-11-011-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | glusterd's brick restart logic is not always sequential as there is atleast three different ways how the bricks are restarted. 1. through friend-sm and glusterd_spawn_daemons () 2. through friend-sm and handling volume quorum action 3. through friend handshaking when there is a mimatch on quorum on friend import. In a brick multiplexing setup, glusterd ended up trying to spawn the same brick process couple of times as almost in fraction of milliseconds two threads hit glusterd_brick_start () because of which glusterd didn't have any choice of rejecting any one of them as for both the case brick start criteria met. As a solution, it'd be better to control this madness by two different flags, one is a boolean called start_triggered which indicates a brick start has been triggered and it continues to be true till a brick dies or killed, the second is a mutex lock to ensure for a particular brick we don't end up getting into glusterd_brick_start () more than once at same point of time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit introduces a new global option that can be set to limit the number of multiplexed bricks in one process. Usage: `# gluster volume set all cluster.max-bricks-per-process <value>` If this option is not set then multiplexing will happen for now with no limitations set; i.e. a brick process will have as many bricks multiplexed to it as possible. In other words the current multiplexing behaviour won't change if this option isn't set to any value. This commit also introduces a brick process instance that contains information about brick processes, like the number of bricks handled by the process (which is 1 in non-multiplexing cases), list of bricks, and port number which also serves as an unique identifier for each brick process instance. The brick process list is maintained in 'glusterd_conf_t'.

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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Test: To reproduce the issue followed below steps 1) Create two distributed volumes(dist1 and dist2) 2) Set cluster.brick-multiplex is on 3) kill glusterd 4) run command gluster v status After apply the patch it shows correct pid for all volumes BUG: 1444596 Change-Id: I5d10af69dea0d0ca19511f43870f34295a54a4d2 Signed-off-by: Mohit Agrawal <moagrawa@redhat.com> Reviewed-on: https://review.gluster.org/17101 Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Prashanth Pai <ppai@redhat.com> 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>
* Fixes quota aux mount failureSanoj Unnikrishnan2017-05-081-5/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* core: run many bricks within one glusterfsd processJeff Darcy2017-01-301-5/+5
| | | | | | | | | | | | | | | | | | | | | | | 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.

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).

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.

* glusterd: use GF_BRICK_STOPPING as intermediate brickinfo->status stateAtin Mukherjee2016-10-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | On a volume stop trigger glusterd issues a brick-op to terminate the brick process during brick-op phase , however in the commit-op glusterd once again tries to kill the same process if it exists and then mark the brickinfo->status flag to GF_BRICK_STOPPED. In the former case, if brick is successfully killed there is a possibility that GlusterD will receive RPC_CLNT_DISCONNECT from the said brick process before even the commit op phase is executed and hence by that time brickinfo->status will still be set to GF_BRICK_STARTED. BRICK_DISCONNECT event should be only sent if a brick has been killed and not through a volume stop/remove brick trigger, however due to this trace, this event is also sent out on a volume stop. Fix is to introduce an intermediate state GF_BRICK_STOPPING which can be used to mark the brick status at brick op phase of volume stop/remove brick to avoid sending spurious BRICK_DISCONNECT events on a volume stop trigger.

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