EC does not release the lock and goes ahead and renames the "new" file with the "already held lock". That causes rebalance process to be blocked on a lock which has been acquired by rename. Solution: While rename fop comes, ec takes blocking inodelk on old and new parent of the file. Before releasing, every lock held by ec, it waits for some "time" to see if that lock can be reused by the next fop. If within this "time" some other request comes, it releases this lock based on condition "lock count > 1" To get this "lock count" for rename fop, we have implemented "pl_rename" in feature/lock. Also, on ec side, changed the condition to release the lock based on the type of fop and old and new parent directories.
