[LU-425] SANITYN sanity_mount_check_clients fails if $MOUNT is a substring of $MOUNT2

• Status: Resolved
• Project: Lustre
• Affects Version/s: Lustre 1.8.6
• Fix Version/s: Lustre 2.3.0, Lustre 2.1.2, Lustre 1.8.8
• Type: Bug
• Priority: Minor
• Reporter: Jay Lan (Inactive)
• Assignee: Jian Yu
• Resolution: Fixed

Environment

My test environment is from git tree with tag 1.8.5.51. The OS should be irrelevant, but I am running sles11sp1 on client.

• Severity: 3

Description

The SANITYN passed all its tests but failed in pre-test
setup at sanity_mount_check_clients.

I defined MOUNT=/mnt/nbp0 and MOUNT2=/mnt/nbp0-2. Bad idea!!!

The sanity_mount_check* scripts use `grep -c` to search for
$MOUNT and $MOUNT2. Since $MOUNT is a substring
of $MOUNT2, `grep` on situations return wrong count!

Changing $MOUNT definition to /mnt/nbp0-1 passed the sanityN.sh test.

Hi Peter,

I am not sure what information you asked for. The change I mentioned was done in my
version of ncli_jlan.sh, not in the lustre/tests/ scripts. Thanks.
