* glusterd: Gluster should keep PID file in correct locationGaurav Kumar Garg2017-08-121-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. > 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: 1480459 Change-Id: Idb09e3fccb6a7355fbac1df31082637c8d7ab5b4 Signed-off-by: Mohit Agrawal <moagrawa@redhat.com> Reviewed-on: https://review.gluster.org/18023 Reviewed-by: Atin Mukherjee <amukherj@redhat.com> Smoke: Gluster Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org>

* glusterd: fix brick start raceAtin Mukherjee2017-06-061-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: socketfile & pidfile related fixes for brick multiplexing featureMohit Agrawal2017-05-091-1/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Unnikrishnan2017-05-081-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem-1 If Lookup which doesn't take any locks observes version mismatch it can't be trusted. If we launch a heal based on this information it will lead to self-heals which will affect I/O performance in the cases where Lookup is wrong. Considering self-heal-daemon and operations on the inode from client which take locks can still trigger heal we can choose to not attempt a heal on Lookup. Problem-2: Fixed spurious failure of tests/bitrot/bug-1373520.t For the issues above, what was happening was that ec_heal_inspect() is preventing 'name' heal to happen Problem-3: tests/basic/ec/ec-background-heals.t To be honest I don't know what the problem was, while fixing the 2 problems above, I made some changes to ec_heal_inspect() and ec_need_heal() after which when I tried to recreate the spurious failure it just didn't happen even after a long time.

* glusterd: keep snapshot bricks separate from regular onesJeff Darcy2017-02-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | 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 Darcy2017-01-301-3/+27
| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: When a file with hardlink is corrupted in ec volume, the recovery steps mentioned was not working. Only name and metadata was healing but not the data. Cause: The bad file marker in the inode context is not removed. Hence when self heal tries to open the file for data healing, it fails with EIO. Background: The bitrot deletes inode context during forget. Briefly, the recovery steps involves following steps. 1. Delete the entry marked with bad file xattr from backend. Delete all the hardlinks including .glusters hardlink as well. 2. Access the each hardlink of the file including original from the mount. The step 2 will send lookup to the brick where the files are deleted from backend and returns with ENOENT. On ENOENT, server xlator forgets the inode if there are no dentries associated with it. But in case hardlinks, the forget won't be called as dentries (other hardlink files) are associated with the inode. Hence bitrot stube won't delete it's context failing the data self heal. Fix: Bitrot-stub should delete the inode context on getting ENOENT during lookup.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) Avoid hangs on unmounting NFS on NetBSD NetBSD umount(8) on a NFS mount whose server is gone will wait forever because umount(8) calls realpath(3) and tries to access the mount before it calls unmount(2). The non-portable, NetBSD-specific umount -R flag prevent that behavior. We therefore introduce UMOUNT_F, defined as "umount -f" on Linux and "umount -f -R" on NetBSD to take care of forced unmounts, especially in the NFS case. 2) Enforce usage of force_umount wrapper with timeout Whenever umount is used it should be wrapped in force_umount with tiemout handling. That saves us timing issues, and it handles the NetBSD NFS case. 3) Cleanup kernel cache flush. We used (cd $M0 && umount $M0 ) as a portable kernel cache flush trick, but it does not flush everything we need on Linux. Introduce a drop_cache() shell function that reverts to previously used echo 3 > /proc/sys/vm/drop_caches on Linux, and keeps (cd $M0 && umount $M0 ) on other systems.

* features/changelog: Consider only changelog on/off as changelog breakageKotresh HR2015-05-021-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Earlier, both chagelog on/off and brick restart were considered to be changelog breakage and treated as changelog not being continuous. As a result, new HTIME.TSTAMP file was created on both the above cases. Now the change is made such that only on changelog enable/disable, the changelog is considered to be discontinuous. New HTIME.TSTAMP file is not created on brick restart, the changelogs files are appended to last HTIME.TSTAMP file. Treating changelog as continuous in above scenario is important as changelog history API will fail otherwise. It can successfully get changes between start and end timestamps only when changelog is continuous (Changelogs in single HTIME.TSTAMP file are treated as continuous). Without this change, changelog history API would fail, and it would become necessary to fallback to other mechanisms like xsync FSCrawl in case geo-rep to detect changes in this time window. But Xsync FSCrawl would not be applicable to other consumers like glusterfind. Rationale: 1. In plain distributed volume, if brick goes down, no I/O can happen onto the brick. Hence changelog is intact with data on disk. 2. In distributed replicate volume, if brick goes down, since self-heal traffic is captured in changelog.

* tests: Await for graph switch before testing open fop countVijay Bellur2015-04-291-0/+7
| | | | | | | | | | | | | | | | | | | | | In performance/open-behind.t, a test for open fop reaching the brick is done by switching off open-behind and performing a read operation. If the read operation is performed before a graph switch, the read happens on the old graph and hence open does not get accounted in the brick. To overcome this EXPECT_WITHIN 10 seconds has now been added to ensure that a graph switch has happened. The read operation happens subsequently after the graph switch. Cleaned up a "No volumes present" message from stderr while doing this.
