storage/posix: Log when mkdir is on an existing gfid but non-existent
path. consider following steps on a distribute volume 1. rename (src, dst) on hashed subvolume 2. snapshot taken 3. restore snapshots and do stat on src and dst Now, we end up with two directories src and dst having same gfid, because of distribute creating directories on non-existent subvolumes as part of directory healing. This can happen even with race between rename and directory healing in dht-lookup. This can lead to undefined behaviour while accessing any of both directories. Hence, we are logging paths of both directories, so that a sysadmin can take some corrective action when (s)he sees this log. One of the corrective action can be to copy contents of both directories from backend into a new directory and delete both directories. Since effort involved to fix this issue is non-trivial, giving this workaround till we come up with a fix.
