* glusterd: fix txn-id mem leakAtin Mukherjee2019-04-092-6/+36
| | | | | | | | | | | | | | | | This commit ensures the following: 1. Don't send commit op request to the remote nodes when gluster v status all is executed as for the status all transaction the local commit gets the name of the volumes and remote commit ops are technically a no-op. So no need for additional rpc requests. 2. In op state machine flow, if the transaction is in staged state and op_info.skip_locking is true, then no need to set the txn id in the priv->glusterd_txn_opinfo dictionary which never gets freed.

* core: make compute_cksum function op_version compatibleSanju Rakonde2019-03-111-4/+8
| | | | | | | | | | | | | | | | | | | | Problem: commit 5a152a changed the mechansim of computing the checksum. In heterogeneous cluster, peers are running into rejected state because we have different cksum computation mechansims in upgraded and non-upgraded nodes. Solution: add a check for op-version so that all the nodes in the cluster follow the same mechanism for computing the cksum. fixes: bz#1684569 > Change-Id: I1508f000e8c9895588b6011b8b6cc0eda7102193 > BUG: bz#1685120 > Signed-off-by: Sanju Rakonde <srakonde@redhat.com> Change-Id: I1508f000e8c9895588b6011b8b6cc0eda7102193 Signed-off-by: Sanju Rakonde <srakonde@redhat.com>
* glusterd: ensure volinfo->caps is set to correct value.Sanju Rakonde2018-11-091-0/+2
| | | | | | | | | | | | | | | | | | | | | | With the commit febf5ed4848, during the volume create op, we are setting volinfo->caps to 0, only if any of the bricks belong to the same node and brickinfo->vg[0] is null. Previously, we used to set volinfo->caps to 0, when either brick doesn't belong to the same node or brickinfo->vg[0] is null. With this patch, we set volinfo->caps to 0, when either brick doesn't belong to the same node or brickinfo->vg[0] is null. (as we do earlier without commit febf5ed4848). > BUG: bz#1635820 > Change-Id: I00a97415786b775fb088ac45566ad52b402f1a49 > Signed-off-by: Sanju Rakonde <srakonde@redhat.com> (cherry picked from commit aae1c402b74fd02ed2f6473b896f108d82aef8e3) fixes: bz#1647968 Change-Id: I00a97415786b775fb088ac45566ad52b402f1a49 Signed-off-by: Sanju Rakonde <srakonde@redhat.com>
* all: fix the format string exceptionsAmar Tumballi2018-11-093-3/+3
| | | | | | | | | | | | | | | | Currently, there are possibilities in few places, where a user-controlled (like filename, program parameter etc) string can be passed as 'fmt' for printf(), which can lead to segfault, if the user's string contains '%s', '%d' in it. While fixing it, makes sense to make the explicit check for such issues across the codebase, by making the format call properly.

* glusterd: allow shared-storage to use bricks under glusterd working directorySanju Rakonde2018-11-086-11/+15
| | | | | | | | | | | | | | | | | | | | With commit 44e4db, we are not allowing user to create a volume using glusterd's working directory as a brick or any sub directory under glusterd's working directory as a brick.This has broken shared-storage since the volume "gluster-shared-storage" is created using the bricks under glusterd's working directory. With this patch, we let the "gluster-shared-storage" volume to use bricks under glusterd's working directory. > BUG: bz#1647029 > Change-Id: Ifcbcf4576eea12cf46f199dea287b29bd3ec3bfd > Signed-off-by: Sanju Rakonde <srakonde@redhat.com> (cherry picked from commit bdb4ca184913c82ccf9552298f5d5b597794f2aa) fixes: bz#1647801 Change-Id: Ifcbcf4576eea12cf46f199dea287b29bd3ec3bfd Signed-off-by: Sanju Rakonde <srakonde@redhat.com>

* mgmt/glusterd: use proper path to the volfileRaghavendra Bhat2018-10-052-7/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Till now, glusterd was generating the volfile path for the snapshot volume's bricks like this. /snaps/<snap name>/<brick volfile> But in reality, the path to the brick volfile for a snapshot volume is /snaps/<snap name>/<snap volume name>/<brick volfile> The above workaround was used to distinguish between a mount command used to mount the snapshot volume, and a brick of the snapshot volume, so that based on what is actually happening, glusterd can return the proper volfile (client volfile for the former and the brick volfile for the latter). But, this was causing problems for snapshot restore when brick multiplexing is enabled. Because, with brick multiplexing, it tries to find the volfile and sends GETSPEC rpc call to glusterd using the 2nd style of path i.e. /snaps/<snap name>/<snap volume name>/<brick volfile> So, when the snapshot brick (which is multiplexed) sends a GETSPEC rpc request to glusterd for obtaining the brick volume file, glusterd was returning the client volume file of the snapshot volume instead of the brick volume file.

* ctime: Provide noatime optionKotresh HR2018-10-021-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | Most of the applications are {c|m}time dependant and very few are atime dependant. So provide noatime option to not update atime when ctime feature is enabled. Also this option has to be enabled with ctime feature to avoid unnecessary self heal. Since AFR/EC reads data from single subvolume, atime is only updated in one subvolume triggering self heal.

* glusterd: acquire lock to update volinfo structureSanju Rakonde2018-09-273-34/+42
| | | | | | | | | | | | | | | | | | | | | | | | 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. > BUG: bz#1627610 > Signed-off-by: Sanju Rakonde <srakonde@redhat.com> > Change-Id: I545e4e2368e3285d8f7aa28081ff4448abb72f5d (cherry picked from commit 484f417da945cf83afdbf136bb4817311862a8d2) fixes: bz#1633552 Change-Id: I545e4e2368e3285d8f7aa28081ff4448abb72f5d Signed-off-by: Sanju Rakonde <srakonde@redhat.com>
* glusterd: make sure that brickinfo->uuid is not nullSanju Rakonde2018-09-271-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: After an upgrade from the version where shared-brick-count option is not present to a version which introduced this option causes issue at the mount point i.e, size of the volume at mount point will be reduced by shared-brick-count value times. Cause: shared-brick-count is equal to the number of bricks that are sharing the file system. gd_set_shared_brick_count() calculates the shared-brick-count value based on uuid of the node and fsid of the brick. https://review.gluster.org/#/c/glusterfs/+/19484 handles setting of fsid properly during an upgrade path. This patch assumed that when the code path is reached, brickinfo->uuid is non-null. But brickinfo->uuid is null for all the bricks, as the uuid is null https://review.gluster.org/#/c/glusterfs/+/19484 couldn't reached the code path to set the fsid for bricks. So, we had fsid as 0 for all bricks, which resulted in gd_set_shared_brick_count() to calculate shared-brick-count in a wrong way. i.e, the logic written in gd_set_shared_brick_count() didn't work as expected since fsid is 0. Solution: Before control reaches the code path written by https://review.gluster.org/#/c/glusterfs/+/19484, adding a check for whether brickinfo->uuid is null and if brickinfo->uuid is having null value, calling glusterd_resolve_brick will set the brickinfo->uuid to a proper value. When we have proper uuid, fsid for the bricks will be set properly and shared-brick-count value will be caluculated correctly. Please take a look at the bug https://bugzilla.redhat.com/show_bug.cgi?id=1632889 for complete RCA Steps followed to test the fix: 1. Created a 2 node cluster, the cluster is running with binary which doesn't have shared-brick-count option 2. Created a 2x(2+1) volume and started it 3. Mouted the volume, checked size of volume using df 4. Upgrade to a version where shared-brick-count is introduced (upgraded the nodes one by one i.e, stop the glusterd, upgrade the node and start the glusterd). 5. after upgrading both the nodes, bumped up the cluster.op-version 6. At mount point, df shows the correct size for volume. > backport of https://review.gluster.org/#/c/glusterfs/+/21278/ > Change-Id: Ib9f078aafb15e899a01086eae113270657ea916b > Signed-off-by: Sanju Rakonde <srakonde@redhat.com> (cherry picked from commit f1e9b878ce2067db83a0baa5f384eda87287719d) fixes: bz#1633242 Change-Id: Ib9f078aafb15e899a01086eae113270657ea916b Signed-off-by: Sanju Rakonde <srakonde@redhat.com>

| | | | | | | | | | | | | | | | | | | | Surprisingly, there is not set_boolean() as there is a get_boolean() In fact, it is stored as an INT dictionary type. In some occasions it was stored using a string, and this caused errors such as: key gfproxy-server, integer type asked, has string type [Invalid argument] I've fixed what I saw in some logs, I'm sure there are more.

* glusterd: fail volume stop operation if brick detach failsAtin Mukherjee2018-09-041-8/+22
| | | | | | | | | | | | | | While sending a detach request for a brick in brick multiplexing mode, in any situation if the brick isn't connected, glusterd will fail to detach the brick but due to the missing error code handling, glusterd will mark the volume as stopped. Fix is to handle the return code of send_attach_req in glusterd_volume_stop_glusterfs () Change-Id: I886202969c96eec3620f74cd7027652d6287f4be Fixes: bz#1624440 Signed-off-by: Atin Mukherjee <amukherj@redhat.com>
