From 683cb46bd90d0cda42e0dfd71f5a5afad818fbbd Mon Sep 17 00:00:00 2001 From: Sanoj Unnikrishnan Date: Wed, 22 Mar 2017 15:02:12 +0530 Subject: Fixes quota aux mount failure The aux mount is created on the first limit/remove_limit/list command and it remains until volume is stopped / deleted / (quota is disabled) , where we do a lazy unmount. If the process is uncleanly terminated, then the mount entry remains and we get (Transport disconnected) error on subsequent attempts to run quota list/limit-usage/remove commands. Second issue, There is also a risk of inadvertent rm -rf on the /var/run/gluster causing data loss for the user. Ideally, /var/run is a temp path for application use and should not cause any data loss to persistent storage. Solution: 1) unmount the aux mount after each use. 2) clean stale mount before mounting, if any. One caveat with doing mount/unmount on each command is that we cannot use same mount point for both list and limit commands. The reason for this is that list command needs mount to be accessible in cli after response from glusterd, So it could be unmounted by a limit command if executed in parallel (had we used same mount point) Hence we use separate mount points for list and limit commands. >Reviewed-on: https://review.gluster.org/16938 >NetBSD-regression: NetBSD Build System >Smoke: Gluster Build System >Reviewed-by: Manikandan Selvaganesh >CentOS-regression: Gluster Build System >Reviewed-by: Raghavendra G >Reviewed-by: Atin Mukherjee >(cherry picked from commit 2ae4b4058691b324535d802f4e6d24cce89a10e5) Change-Id: I4f9e39da2ac2b65941399bffb6440db8a6ba59d0 BUG: 1449775 Signed-off-by: Sanoj Unnikrishnan Reviewed-on: https://review.gluster.org/17240 Smoke: Gluster Build System NetBSD-regression: NetBSD Build System CentOS-regression: Gluster Build System Reviewed-by: Atin Mukherjee --- tests/basic/quota-nfs.t | 1 - 1 file changed, 1 deletion(-) (limited to 'tests/basic/quota-nfs.t') diff --git a/tests/basic/quota-nfs.t b/tests/basic/quota-nfs.t index 74fde400bd1..663a8da90ad 100755 --- a/tests/basic/quota-nfs.t +++ b/tests/basic/quota-nfs.t @@ -58,7 +58,6 @@ TEST rm -f $N0/$deep/newfile_2 EXPECT_WITHIN $UMOUNT_TIMEOUT "Y" umount_nfs $N0 TEST $CLI volume stop $V0 -EXPECT "1" get_aux rm -f $QDD cleanup; -- cgit
