dht: rename takes lock on parent directory if destination exists

2016-05-20T10:54:56+00:00

For directory rename if destination exists the source directory
is created as a child of the given destination directory. Since
the new child directory does not exist take lock on parent of the
child directory.

tier/detach: Clear tier-fix-layout-complete xattr after migration threads join

2016-05-18T20:04:33+00:00

Previously we had wrongly placed the clearing tier-fix-layout-complete
xattr before the joining of migration threads. This would lead to
situations where failure of clearing the xattr would cause the
premature death of migration threads.

Now we clear the xattr only after the data movement threads join,
ensuring that all migration is done.

cluster/dht: handle EREMOTE in dht lk/flush

2016-05-02T01:05:08+00:00

With lock-migration, we need to send requests to destination
brick post migration. Once, the source brick marks the lock
structure to be already migrated, the requests will be redirected
to destination brick by dht_lk2/flush2.

tier/migrator: Fetch the next query file for the next cycle

2016-04-30T14:30:49+00:00

Problem: When we spawn promote and demote thread, query files
are build. And only query file with index 0 is picked for migration
as the first query file. This may not be suitable for scenarios,
where the file in the query are too big to move in the first cycle,
as a result file in the other query files always get missed. We need to
shuffle so that other query files also get a chance.

Fix: Remember the previous first query file and shift it by one index,
before the migration starts.
