From 0cc24da2fd79dd8680b771475d2192db0b63e7de Mon Sep 17 00:00:00 2001 From: Pranith Kumar K Date: Wed, 2 Aug 2017 07:22:13 +0530 Subject: extras: Turn eager-lock off for gluster-block With the current implementation of eager-lock FINODELK is taking so much time that cassandra workload times out and errors out. AFR eager-locking needs to be changed similar to EC eager-locking to make things work as expected. In the interim, it is better to turn it off This is how the profile looks if eager-lock is turned on: 0.35 628.26 us 64.00 us 129882.00 us 42278 FXATTROP 17.45 16500.54 us 212.00 us 375829.00 us 79568 WRITE 81.76 209862.12 us 15.00 us 1992486.00 us 29318 FINODELK This is how profile looks if eager-lock is turned off: 1.87 283.71 us 65.00 us 298970.00 us 68346 FXATTROP 6.33 199.04 us 13.00 us 373428.00 us 330524 FINODELK 10.37 3151.47 us 53.00 us 1528484.00 us 34172 FSYNC 81.31 5110.45 us 270.00 us 1519722.00 us 165244 WRITE BUG: 1477404 Change-Id: I98026b1ecf30002ddac01be76f375c2e8c0b7838 Signed-off-by: Pranith Kumar K Reviewed-on: https://review.gluster.org/17954 CentOS-regression: Gluster Build System Smoke: Gluster Build System Tested-by: Krutika Dhananjay Reviewed-by: Krutika Dhananjay --- extras/group-gluster-block | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'extras') diff --git a/extras/group-gluster-block b/extras/group-gluster-block index 12d5f90448c..82bd6ff5e72 100644 --- a/extras/group-gluster-block +++ b/extras/group-gluster-block @@ -5,7 +5,7 @@ performance.stat-prefetch=off performance.open-behind=off performance.readdir-ahead=off network.remote-dio=disable -cluster.eager-lock=enable +cluster.eager-lock=disable cluster.quorum-type=auto cluster.data-self-heal-algorithm=full cluster.locking-scheme=granular -- cgit
