cluster/afr: Prevent split-brain when bricks are brought off and on in cyclic order

2016-08-22T10:22:36+00:00

        Backport of: http://review.gluster.org/15080

When the bricks are brought offline and then online in cyclic
order while writes are in progress on a file, thanks to inode
refresh in write txns, AFR will mostly fail the write attempt
when the only good copy is offline. However, there is still a
remote possibility that the file will run into split-brain if
the brick that has the lone good copy goes offline *after* the
inode refresh but *before* the write txn completes (I call it
in-flight split-brain in the patch for ease of reference),
requiring intervention from admin to resolve the split-brain
before the IO can resume normally on the file. To get around this,
the patch does the following things:
i) retains the dirty xattrs on the file
ii) avoids marking the last of the good copies as bad (or accused)
    in case it is the one to go down during the course of a write.
iii) fails that particular write with the appropriate errno.

This way, we still have one good copy left despite the split-brain situation
which when it is back online, will be chosen as source to do the heal.

glusterd: Convert volume to replica after adding brick self heal is not triggered

2016-08-18T16:55:17+00:00

Problem:  After add brick to a distribute volume to convert to replica is not
          triggering self heal.

Solution: Modify the condition in brick_graph_add_index to set trusted.afr.dirty
          attribute in xlator.

Test    : To verify the patch followd below steps
          1) Create a single node volume
             gluster volume create  
          2) Start volume and create mount point
             mount -t glusterfs :/DIS /mnt
          3) Touch some file and write some data on file
          4) Add another brick along with replica 2
             gluster volume add-brick DIS replica 2 :/dist2/brick2
          5) Before apply the patch file size is 0 bytes in mount point.

glusterd: Fix volume restart issue upon glusterd restart

2016-08-18T08:39:34+00:00

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.

posix: Do not move and recreate .glusterfs/unlink directory

2016-08-10T09:31:50+00:00

Problem:
At the time of start of a volume, it is checked if
.glusterfs/unlink exist or not. If it does, move it
to landfill and recreate unlink directory. If a volume
is mounted and we write data on it till we face ENOSPC,
restart of that volume fails as it will not be able to
create unlink dir. mkdir will fail with ENOSPC.
This will not allow volume to restart.

Solution:
If .glusterfs/unlink directory exist, don't move it to
landfill. Delete all the entries inside it.

glusterd : skip non directories inside /var/lib/glusterd/vols

2016-08-09T15:03:14+00:00

Right now glusterd won't come up if vols directory contains an invalid entry.
Instead of doing that with this change a message will be logged and then skip
that entry

Instead of rebalance stop, its always better to wait for rebalance to complete
as the former doesn't have any purpose.

commit 3c04a91 removed setting typeStr to NULL if num_allocs is set to 0, this

xlator/trash : append '/' at the end in trash_notify_lookup_cbk

2016-08-05T07:51:28+00:00

In the notify function in trash xlator, a lookup is performed
to obtain path of old trash directory. The result usually contains
path without '/' at the end. The trash xlator maintains expects
'/' at the end for the values such as 'old trash dir' and
'new trash dir'. Otherwise certian checks in the code will fail.
