io-stats: Add stats for upcall notifications

2016-09-01T03:18:42+00:00

With this patch, there will be additional entries seen in
the profile info:

UPCALL : Total number of upcall events that were sent from
         the brick(in brick profile), and number of upcall
         notifications recieved by client(in client profile)

Cache invalidation events:
-------------------------
CI_IATT : Number of upcalls that were cache invalidation and
         had one of the IATT_UPDATE_FLAGS set. This indicates
         that one of the iatt value was changed.

CI_XATTR : Number of upcalls that were cache invalidation, and
         had one of the UP_XATTR or UP_XATTR_RM set. This indicates
         that an xattr was updated or deleted.

CI_RENAME : Number of upcalls that were cache invalidation,
         resulted by the renaming of a file or directory

CI_UNLINK : Number of upcalls that were cache invalidation,
         resulted by the unlink of a file.

CI_FORGET : Number of upcalls that were cache invalidation,
         resulted by the forget of inode on the server side.

Lease events:
------------
LEASE_RECALL : Number of lease recalls sent by the brick (in
         brick profile), and number of lease recalls recieved
         by client(in client profile)

Note that the sum of CI_IATT, CI_XATTR, CI_RENAME, CI_UNLINK,
CI_FORGET, LEASE_RECALL may not be equal to UPCALL. This is
because, each cache invalidation can carry multiple flags.
Eg:
- Every CI_XATTR will have CI_IATT
- Every CI_UNLINK will also increment CI_IATT as link count is an
iatt attribute.

Also UP_PARENT_DENTRY_FLAGS is currently not accounted for,
as CI_RENAME and CI_UNLINK will always have the flag
UP_PARENT_DENTRY_FLAGS

afr: afr-pending-xattr fallback check

2016-06-09T08:20:43+00:00

Commit 6e635284a4411b816d4d860a28262c9e6dc4bd6a introduced a comma
separated list of values to be used as AFR's pending changelogs. If
this xlator option is missing in the volfile, fall back to using client
xlator names for constructing the pending changelog names.

Also, since the aforementioned commit was reverted from 3.7 and 3.8
branches, introduce GD_OP_VERSION_3_9_0 and change the op-version for this
feature to GD_OP_VERSION_3_9_0.

glusterd/ afr: Fix op-version for background client-side heals

2016-03-23T02:19:11+00:00

http://review.gluster.org/13207 tied cluster.heal-wait-queue-length to
GD_OP_VERSION_3_7_9 but the patch will be merged in release-3.7 branch
(http://review.gluster.org/#/c/13564/) only for 3.7.10.
Hence change it on master also for uniformity.

glusterd / afr : Enable auto heal when replica count increases

2016-03-21T17:51:00+00:00

In replicate volumes, when a brick is added to a replicate
group, heal to the new brick should be triggered.
Also, the new brick should not be considered as source for
healing till it is up to date.

Previously, extended attributes had to be set manually on
the bricks for this to happen. This patch is part 1 patch
to automate this process.
