+++ This bug was initially created as a clone of Bug #1637802 +++ Description of problem: commit eb472d82a083883335bc494b87ea175ac43471ff in master introduced a bug where a data-self-heal on a file in arbiter leaves a stale inodelk behind on the bricks. Thus any new write to the file from a client can hang How reproducible: Always. Steps to Reproduce: 1. Create 1x (2+1) arbiter, fuse mount it and create a file 2. Kill arbiter brick, write to the file, bring back arbiter and let self-heal complete. 3. Next write to the file from mount will hang because the inodelk gets blocked because of the previous stale locks left behind from self-heal Additional info: Downstream bug which found the issue: BZ 1636902 --- Additional comment from Worker Ant on 2018-10-10 02:56:21 EDT --- REVIEW: https://review.gluster.org/21380 (afr: prevent winding inodelks twice for arbiter volumes) posted (#1) for review on master by Ravishankar N

COMMIT: https://review.gluster.org/21384 committed in release-4.1 by "Ravishankar N" <ravishankar> with a commit message- afr: prevent winding inodelks twice for arbiter volumes Backport of https://review.gluster.org/#/c/glusterfs/+/21380/ Problem: In an arbiter volume, if there is a pending data heal of a file only on arbiter brick, self-heal takes inodelks twice due to a code-bug but unlocks it only once, leaving behind a stale lock on the brick. This causes the next write to the file to hang. Fix: Fix the code-bug to take lock only once. This bug was introduced master with commit eb472d82a083883335bc494b87ea175ac43471ff Thanks to Pranith Kumar K <pkarampu> for finding the RCA. fixes: bz#1637953 Change-Id: I15ad969e10a6a3c4bd255e2948b6be6dcddc61e1 Signed-off-by: Ravishankar N <ravishankar>
