        Backport of: http://review.gluster.org/14623

For o-direct reads application sends aligned size which needs to be
sent as is, otherwise o-direct writes where the file-size is not
aligned fails.

afr: Consider ENOSPC and EDQUOT as symmetric errors

2016-06-13T06:42:23+00:00

Backport of http://review.gluster.org/#/c/14604/

Problem:
Since commit 8eaa3506ead4f11b81b146a9e56575c79f3aad7b, in replica 3, if a
brick is down and a create fails on the other 2 brick with EDQUOT, we consider
it an unsymmetric error and hence do not do post-op. So the dirty xattr
remains set on the parent dir, leading to conservative merges during heal when
all bricks are up. i.e. a file deleted on the source might re-appear after heal.

Fix:
Consider ENOSPC and  EDQUOT as symmetric errors since there is no
possibility of partial inode or entry modification operations possible when
quota is enabled. IOW, if quota reports EDQUOT, the no. of bytes written
(or not written) will be the same on all bricks of the replica.
Likewise, the entry operation (create, mkdir...) will either succeed or
not succeed on all bricks.

Backport of http://review.gluster.org/#/c/13974

There is no need to unmount the brick as doing so we loose all the xattrs on the
brick and while restarting glusterd brick doesn't come up

tests/write-behind: move 1279730.t to BAD tests

2016-05-27T07:46:30+00:00

There is a race condition which is causing the test to fail. For lack
of bandwidth I am moving this test to BAD, though clearly there is
some issue with codebase.

cluster/afr: Do not inode_link in afr

2016-05-26T12:54:25+00:00

Race is explained at
https://bugzilla.redhat.com/show_bug.cgi?id=1337405#c0

This patch also handles performing of self-heal with shd-pid.
Also performs the healing with this->itable's inode rather than
main itable.

cluster/afr: Do heals with shd pid

2016-05-24T17:09:59+00:00

Multi-threaded healing doesn't create synctask with shd pid, this
leads to healing problems when quota exceeds.

cluster/afr : Do post-op in case of symmetric errors

2016-05-24T05:21:35+00:00

        Backport of: http://review.gluster.org/#/c/14310/

In afr_changelog_post_op_now(), if there was any error,
meaning op_ret < 0, post-op was not being done even when
the errors were symmetric and there were no "failed
subvols".

Fix:
When the errors are symmetric, perform post-op.

How was the bug found :
In a 1 X 3 volume with shard and write behind on
when writes were done into a file with one brick down,
the trusted.afr.dirty xattr's value for .shard directory
would keep increasing as post op was not done but pre-op was.
This incorrectly showed .shard to be in split-brain.

RCA:
When WB is on, due to multiple writes being sent on
offset lying in the same shard, chances are that
same shard file will be created more than once
with the second one failing with op_ret < 0
and op_errno = EEXIST.

As op_ret was negative, afr wouldn't do post-op,
leading to no decrement of trusted.afr.dirty xattr.
Thus showing .shard directory to be in split-brain.

tier/cli : printing a warning instead of skipping the node

2016-05-20T18:19:49+00:00

        back-port of : http://review.gluster.org/#/c/14347/8

Problem: skipping the status of the nodes down creates confusion
to the user as one might see the status as completed for all nodes
and while performing detach commit, the operation will fail as the
node is down

Fix: Display a warning message

Note: When the last node is down (as per the peer list) then
warning message can't be displayed as the total number of peers
participating in the transaction is considered to be the total count.
