• Status: Resolved
• Project: Lustre
• Affects Version/s: Lustre 2.5.0
• Fix Version/s: Lustre 2.5.0
• Type: Bug
• Priority: Minor
• Reporter: James Nunez (Inactive)
• Assignee: James Nunez (Inactive)
• Resolution: Fixed
• Labels: HSM, patch

Environment

OpenSFS cluster with combined MGS/MDS, single OSS with two OSTs, four clients; one agent (c07), one with robinhood/db running (c08) and just running as Lustre clients (c09, c10)

• Severity: 3

Description

Test results are at https://maloo.whamcloud.com/test_sets/28e49004-2171-11e3-b1f0-52540035b04c

This may just be an error in the test. From John Hammond:

I think 9a is a bug in the test.
0x00000001 should be 0x00000009.

From the test log, we see

I think the following are harmless, but dmesg on the MDS shows the following:

Agree: test 9a is buggy 0x00000001 must be replaced by 0x00000009 (ARCHIVED + EXIST). If you do the patch please do also following change:

• replace need2clients by needclients which will take a client count as arg

• test_9a should be changed to use needclients 3

• need2clients should be changed to use needclients 2

I can do the patch

I'm tied up with HSM testing. So, I don't plan to create a patch for this test. Please create and submit the patch if you have time.

Thanks, James
