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: Refresh inode for inode-write fops in need

2016-05-24T21:42:30+00:00

Problem:
If a named fresh-lookup is done on an loc and the fop fails on one of the
bricks or not sent on one of the bricks, but by the time response comes to afr,
if the brick is up, 'can_interpret' will be set to false in afr_lookup_done(),
this will lead to inode-ctx for that inode to be not set, this can lead to EIO
in case of a transaction as it depends on 'readable' array to be available by
that point.

Fix:
Refresh inode for inode-write fops for the ctx to be set if it is not already
done at the time of named fresh-lookup or if the file is in split-brain where
we need to perform one more refresh before failing the fop to check if the file
is still in split-brain or not.

gfapi/upcall: Use GF_CALLOC while allocating variables

2016-05-24T18:20:09+00:00

In 'glfs_h_poll_cache_invalidation', use GF_CALLOC to allocate
'up_inode_arg' to set memory accounting which is used/referred when
freeing the same variable in case of any erros.

build: include a dummy config.sub and config.guess in releases

2016-05-24T14:10:52+00:00

There is no hard requirement for a config.guess and config.sub script in
the release tarball. By passing --build=... and --host=... to
./configure, the scripts are not executed.  When doing local builds, the
./autogen.sh script (by running automake) will place a config.guess and
config.sub script in the root of the source tree. Upon creation of the
release ('make dist') tarball, the scripts are replaced by dummy copies
from the build-aux/ directory.

The main advantage to not include these scripts in the repository, is
that there is no need to track upstream updates for them either.

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

2016-05-24T13:26:16+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: Check for required number of entrylks

2016-05-24T11:19:58+00:00

Backport of http://review.gluster.org/#/c/14358/

Problem:
Parallel rmdir operations on the same directory results in ENOTCONN
messages eventhough there was no network disconnect.

In blocking entry lock during rmdir, AFR takes 2 set of locks on all its
children-One (parentdir,name of dir to be deleted), the other (full lock
on the dir being deleted). We proceed to pre-op stage even if only a
single lock (but not all the needed locks) was obtained, only to fail it with
ENOTCONN because afr_locked_nodes_get() returns zero nodes  in
afr_changelog_pre_op().

Fix:
After we get replies for all blocking lock requests, if we don't have
the minimum number of locks to carry out the FOP, unlock and fail the
FOP. The op_errno will be that of the last failed reply we got, i.e.
whatever is set in afr_lock_cbk().

cluster/afr: If possible give errno received from lower xlators

2016-05-24T10:40:44+00:00

In case of 3 way replication with quorum enabled with sharding,
if one bricks is brought down and brought back up sometimes
fops fail with EROFS because the mknod of shard file fails with
two good nodes with EEXIST. So even when quorum is not met, it
makes sense to unwind with the errno returned by lower xlators
as much as possible.

common-ha: wait for cluster to elect DC before accessing CIB

2016-05-24T09:36:16+00:00

access attempts, e.g. `pcs property set stonith-enabled=false`
will fail (or time out) if attempted "too early", i.e. before
the cluster has elected its DC.
