COMMIT: http://review.gluster.org/15030 committed in master by Pranith Kumar Karampuri (pkarampu) ------ commit a432e7bc80dee70a48ccc5f04f5574cdce18a3a5 Author: Ashish Pandey <aspandey> Date: Wed Jul 27 15:49:25 2016 +0530 posix: Do not move and recreate .glusterfs/unlink directory Problem: At the time of start of a volume, it is checked if .glusterfs/unlink exist or not. If it does, move it to landfill and recreate unlink directory. If a volume is mounted and we write data on it till we face ENOSPC, restart of that volume fails as it will not be able to create unlink dir. mkdir will fail with ENOSPC. This will not allow volume to restart. Solution: If .glusterfs/unlink directory exist, don't move it to landfill. Delete all the entries inside it.
