cluster/ec: Node uuid xattr support update for EC

2017-06-26T10:32:31+00:00

        Backport of https://review.gluster.org/17594

Problem:
The change in EC to return list of node uuids for
GF_XATTR_NODE_UUID_KEY was causing problems with
geo-rep.

Fix:
This patch will allow to get the single node uuid
as it was doing before with the key
"GF_XATTR_NODE_UUID_KEY", and will also allow to get
the list of node uuids by using a new key
"GF_XATTR_LIST_NODE_UUIDS_KEY". This will solve
the problem with geo-rep and any other features which
were depending on this.

cluster/dht: Additional checks for rebalance estimates

2017-06-22T20:54:08+00:00

The rebalance estimates calculation was not handling
calculations correctly when no files had been processed,
i.e., when rate_lookedup was 0.

Now, the estimated time is set to 0 in such scenarios as
there is no way for rebalance to figure out how long the
process will take to complete without knowing the rate at
which the files are being processed.

readdir-ahead: Fix duplicate listing and cache size calculation

2017-06-21T12:48:09+00:00

Issue:
If a opendir is followed by a closedir without readdir, though
the prefetched entries were freed, the freed size was not accounted
in priv->rda_cache_size. Thus the cache limit will exceed if there
are multiple opendir followed by closedir.

Fix:
Fix the pric->rda_cache_size calculation. Also have removed the
inode_ctx_size. Each perf xlator has its own cache limit that
it works with. Also the inode_ctx size can change, if a forget/
invalidate or any other factor triggers the inode_ctx size.

cluster/afr: Implement quorum for lk fop

2017-06-20T13:49:23+00:00

Problem:
At the moment when we have replica 3 or arbiter setup, even when
lk succeeds on just one brick we give success to application which
is wrong

Fix:
Consider quorum-number of successes as success when quorum is enabled.

posix: Revert modifying op_errno in __posix_fd_ctx_get

2017-06-20T13:47:02+00:00

https://review.gluster.org/#/c/17414/ converted ENOENT to EBADFD because
ENOENT is not a valid error for fd based operations, but this apparently
breaks dht rebalance behaviour (see comments in the backport 17517. So
reverting that part of the change.
