[LU-2571] test: lfsck FAIL: lfsck returned 127, should be <= 1

• Status: Resolved
• Project: Lustre
• Affects Version/s: Lustre 2.3.0, Lustre 2.1.3
• Fix Version/s: Lustre 2.4.0
• Type: Bug
• Priority: Minor
• Reporter: Jay Lan (Inactive)
• Assignee: Emoly Liu
• Resolution: Fixed

Environment

Server: 2.1.3-1nasS, centos 6.3, 2.6.32_279.2.1.el6
Client: 2.3.0-2nasC, sles11sp2, 3.0.42_0.7.3
1 mds (S337), 2 oss (S361, S362), 2 clients (S331, S332)

• Severity: 3

Description

This test failed in both 2.3.0 client and 2.1.3 client.

It failed because the test suite try to execute lfsck at the client, which does not have e2fsprogs rpm installed and caused "command not found" error: (see dmsg log of service331)
lfsck -c -l --mdsdb /var/acc-sm-shared/mdsdb --ostdb /var/acc-sm-shared/ostdb-0 /var/acc-sm-shared/ostdb-1 /mnt/nbp0-1
/usr/lib64/lustre/tests/test-framework.sh: line 3246: lfsck: command not found
lfsck : @@@@@@ FAIL: lfsck -c -l --mdsdb /var/acc-sm-shared/mdsdb --ostdb /var/acc-sm-shared/ostdb-0 /var/acc-sm-shared/ostdb-1 /mnt/nbp0-1 returned 127, should be <= 1

The return code '127' is when command not found.

If I allow the return code to be either <= 1 or equals to 127, the test suite would complete. I do not understand why the test suite that tries to execute lfsck on client. If e2fsprogs rpm is not required on clients, the test is flawed.

Test_logs tarball is attached.

Could you please look into this issue?

Thanks

OK, I will have a look.

[Emoly Liu]

Usually we install e2fsprogs rpm on all the nodes by default and run lfsck on client. But, I agree that it's not necessary to have e2fsprogs rpm on clients.

I have some ideas to fix this check:
1. only install lfsck on client, instead of the whole e2fsprogs rpm, and
2. let me check if we can run lfsck on server and then modify the test script.

Andreas, do you have any advice?

[Andreas Dilger]

If the fikesystem is mounted on the MDS this would allow LFSCK lfsck to be run there.

If you guys feel no need to address this issue, I am OK you close this bug. I have changed my setup to always include /usr/sbin/lfsck in my environment.

Jay, the patch is ready for landing. Oleg, will we land it soon?

Landed for 2.4
