COMMIT: http://review.gluster.org/12061 committed in release-3.7 by Kaushal M (kaushal) ------ commit 300a69669aa6e9ebb16e5fc8326ac57c3e2d8937 Author: Krutika Dhananjay <kdhananj> Date: Mon Aug 31 12:43:36 2015 +0530 features/shard: Fix unlink failure due to non-existent shard(s) Backport of: http://review.gluster.org/#/c/12059/ Unlink of a sharded file with holes was leading to EINVAL errors because it was being wound on non-existent shards (those blocks that fall in the hole region). loc->inode was NULL in these cases and dht_unlink used to fail the FOP with EINVAL for failure to fetch cached subvol for the inode. The fix involves winding unlink on only those shards whose corresponding inodes exist in memory.
