[LU-2097] sanity.sh test_17m, lfsck: e2fsck failed due to MDT quota accounting error

• Type: Bug
• Resolution: Fixed
• Priority: Blocker
• Fix Version/s: Lustre 2.4.0
• Affects Version/s: Lustre 2.4.0

Environment

Single node test system (client, MDT, 3x OSTs on same node), x86_64
Lustre master "LU-1842 quota: add quotactl support on qmt" (commit 294aa9cb666c48e02da1057c222fe5f206ce38fc)

• Severity: 3
• Assignee: Niu Yawei (Inactive)
• Reporter: Andreas Dilger

Description

Running acc-sm on a local ldiskfs test system causes e2fsck to fail when checking the MDT in sanity.sh test_17m. I'm running e2fsprogs-1.42.5.wc3-7.fc13.x86_64, which I don't think is the issue, but it hasn't been released yet.

It isn't clear when the quota accounting issue is first introduced (even if it is present when the filesystem is formatted), but the problem needs to be resolved for 2.4.0 and/or the e2fsprogs-1.42.5.wc3 release.

== sanity test 17m: run e2fsck against MDT which contains short/long symlink 21:55:58 (1349409358)
create 512 short and long symlink files under /mnt/testfs/d0.sanity/d17m
erase them
recreate the 512 symlink files with a shorter string
stop and checking mds1: e2fsck -fnvd /dev/vg_sookie/lvmdt1
