cluster/afr: Fix partial heals in 3-way replication
Problem: When there are 2 sources and one sink and if two self-heal daemons try to acquire locks at the same time, there is a chance that it gets a lock on one source and sink leading partial to heal. This will need one more heal from the remaining source to sink for the complete self-heal. This is not optimal. Fix: Upgrade non-blocking locks to blocking lock on all the subvolumes, if the number of locks acquired is majority and there were eagains. >BUG: 1318751 >Change-Id: Iae10b8d3402756c4164b98cc49876056ff7a61e5 >Signed-off-by: Pranith Kumar K <> >Reviewed-on: >Smoke: Gluster Build System <> >NetBSD-regression: NetBSD Build System <> >CentOS-regression: Gluster Build System <> >Reviewed-by: Ravishankar N <> >(cherry picked from commit 8deedef565df49def75083678f8d1558c7b1f7d3) Change-Id: Ia164360dc1474a717f63633f5deb2c39cc15017c BUG: 1327863 Signed-off-by: Pranith Kumar K <> Reviewed-on: Smoke: Gluster Build System <> NetBSD-regression: NetBSD Build System <> CentOS-regression: Gluster Build System <>
