<content type='text'>
After add-brick and rebalance, the ctime xattr is not present
on rebalanced directories on new brick. This patch fixes the
same.

Note that ctime still doesn't support consistent time across
distribute sub-volume.

This patch also fixes the in-memory inconsistency of time attributes
when metadata is self healed.

<title>cluster/afr: Fix incorrect reporting of gfid &amp; type mismatch</title>

<id>908d3bc0b34489c506fafa0f796f6d710768d934</id>
<content type='text'>
Problems:
1. When checking for type and gfid mismatch, if the type or gfid
is unknown because of missing gfid handle and the gfid xattr
it will be reported as type or gfid mismatch and the heal will
not complete.

2. If the source selected during entry heal has null gfid the same
will be sent to afr_lookup_and_heal_gfid(). In this function when
we try to assign the gfid on the bricks where it does not exist,
we are considering the same gfid and try to assign that on those
bricks. This will fail in posix_gfid_set() since the gfid sent
is null.

Fix:
If the gfid sent to afr_lookup_and_heal_gfid() is null choose a
valid gfid before proceeding to assign the gfid on the bricks
where it is missing.

In afr_selfheal_detect_gfid_and_type_mismatch(), do not report
type/gfid mismatch if the type/gfid is unknown or not set.

Problem:
tests/bugs/replicate/bug-1717819-metadata-split-brain-detection.t fails
intermittently in test cases #49 &amp; #50, which compare the values of the
user set xattr values after enabling the heal. We are not waiting for
the heal to complete before comparing those values, which might lead
those tests to fail.

Fix:
Wait till the HEAL-TIMEOUT before comparing the xattr values.
Also cheking for the shd to come up and the bricks to connect to the shd
process in another case.

<title>Cluster/afr: Don't treat all bricks having metadata pending as split-brain</title>

<id>1b0b869d91d4e5bedc69922128551602dc4bbc13</id>
<content type='text'>
Problem:
We currently don't have a roll-back/undoing of post-ops if quorum is not met.
Though the FOP is still unwound with failure, the xattrs remain on the disk.
Due to these partial post-ops and partial heals (healing only when 2 bricks
are up), we can end up in metadata split-brain purely from the afr xattrs
point of view i.e each brick is blamed by atleast one of the others for
metadata. These scenarios are hit when there is frequent connect/disconnect
of the client/shd to the bricks.

Fix:
Pick a source based on the xattr values. If 2 bricks blame one, the blamed
one must be treated as sink. If there is no majority, all are sources. Once
we pick a source, self-heal will then do the heal instead of erroring out
due to split-brain.
This patch also adds restriction of all the bricks to be up to perform
metadata heal to avoid any metadata loss.

Removed the test case tests/bugs/replicate/bug-1468279-source-not-blaming-sinks.t
as it was doing metadata heal even when only 2 of 3 bricks were up.

<title>cluster/afr: Remove local from owners_list on failure of lock-acquisition</title>

<content type='text'>
When eager-lock lock acquisition fails because of say network failures, the
local is not being removed from owners_list, this leads to accumulation of
waiting frames and the application will hang because the waiting frames are
under the assumption that another transaction is in the process of acquiring
lock because owner-list is not empty. Handled this case as well in this patch.
Added asserts to make it easier to find these problems in future.
