cluster/afr: Returning single and list of node uuids from AFR

2017-06-20T12:32:08+00:00

Problem:
The change in afr to return list of node uuids 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 feature which were depending on this.

cluster/afr: Return the list of node_uuids for the subvolume

2017-05-17T18:45:51+00:00

Problem:
AFR was returning the node uuid of the first node for every file if
the replica set was healthy, which was resulting in only one node
migrating all the files.

Fix:
With this patch AFR returns the list of node_uuids to the upper layer,
so that they can decide on which node to migrate which files, resulting
in improved performance. Ordering of node uuids will be maintained based
on the ordering of the bricks. If a brick is down, then the node uuid
for that will be set to all zeros.

afr: misc performance improvements

2016-03-08T14:13:46+00:00

1. In afr_getxattr_cbk, consider the errno value before blindly
launching an inode refresh and a subsequent retry on other children.

2. We want to accuse small files only when we know for sure that there is no
IO happening on that inode. Otherwise, the ia_sizes obtained in the
post-inode-refresh replies may mismatch due to a race between
inode-refresh and ongoing writes, causing spurious heal launches.

afr : get split-brain-status in a synctask

2015-09-14T09:56:53+00:00

On executing `getfattr -n replica.split-brain-status ` on mount,
there is a possibility that the mount hangs. To avoid this hang,
fetch the split-brain-status of a file in synctask.
