From 4a5d8f65b9b04385dcae8b16a650f4e8ed357f8b Mon Sep 17 00:00:00 2001 From: Ravishankar N Date: Tue, 22 Mar 2016 14:26:32 +0530 Subject: afr: Add throttled background client-side heals Backport of: http://review.gluster.org/13207 If a heal is needed after inode refresh (lookup, read_txn), launch it in the background instead of blocking the fop (that triggered refresh) until the heal happens. afr_replies_interpret() is modified such that the heal is launched only if atleast one sink brick is up. Max. no of heals that can happen in parallel is configurable via the 'background-self-heal-count' volume option. Any number greater than that is put in a wait queue whose length is configurable via 'heal-wait-queue-leng' volume option. If the wait queue is also full, further heals will be ignored. Default values: background-self-heal-count=8, heal-wait-queue-leng=128 Change-Id: I9a134b2c29d66b70b7b1278811bd504963aabacc BUG: 1313312 Signed-off-by: Ravishankar N Reviewed-on: http://review.gluster.org/13564 Smoke: Gluster Build System NetBSD-regression: NetBSD Build System CentOS-regression: Gluster Build System Reviewed-by: Pranith Kumar Karampuri --- tests/basic/afr/client-side-heal.t | 1 + 1 file changed, 1 insertion(+) (limited to 'tests/basic') diff --git a/tests/basic/afr/client-side-heal.t b/tests/basic/afr/client-side-heal.t index 18f76265b29..d87f4b14063 100644 --- a/tests/basic/afr/client-side-heal.t +++ b/tests/basic/afr/client-side-heal.t @@ -70,6 +70,7 @@ EXPECT 7 get_pending_heal_count $V0 EXPECT_WITHIN $UMOUNT_TIMEOUT "Y" force_umount $M0 TEST glusterfs --volfile-id=$V0 --volfile-server=$H0 --entry-timeout=0 $M0; TEST cat $M0/datafile +EXPECT_WITHIN $HEAL_TIMEOUT 6 get_pending_heal_count $V0 EXPECT_WITHIN $UMOUNT_TIMEOUT "Y" force_umount $M0 TEST glusterfs --volfile-id=$V0 --volfile-server=$H0 --entry-timeout=0 $M0; -- cgit
