cluster/afr: Remove eager-lock stub on finodelk failure

2014-04-02T17:50:32+00:00

Problem:
For write fops afr's transaction eager-lock init adds transactions
that can share eager-lock to fdctx list. But if eager-lock finodelk
fop fails the stub remains in the list. This could later lead to
corruption of the list and lead to infinite loop on the list
leading to a mount hang.

Fix:
Remove the stub when finodelk fails.

DHT/Rebalance : Hard link Migration Failure

2014-03-30T07:55:43+00:00

Probelm : __is_file_migratable used to return ENOTSUP
for all the cases. Hence, it will add to the failure
count. And the remove-brick status will show failure
for all the files.

Solution : Added 'ret = -2' to gf_defrag_handle_hardlink to
be deemed as success. Otherwise dht_migrate_file will try to
migrate each of the hard link, which not intended.
