    cluster/ec: Rebalance hangs during rename
    
    Problem:
    During the rename of a particular file (ec
    is holding blocking inodelk on the parent
    directory), if the rename of another file
    under the same directory comes. 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.

This bug is getting closed because a release has been made available that should address the reported issue. In case the problem is still not fixed with glusterfs-3.8.0, please open a new bug report.

glusterfs-3.8.0 has been announced on the Gluster mailinglists [1] a while back, and packages for several distributions should be available by now.
