[LU-6660] interop DNE2 test between 2.5/2.7 clients and DNE2 servers

• Type: Task
• Resolution: Fixed
• Priority: Blocker
• Fix Version/s: Lustre 2.8.0
• Assignee: Lai Siyao
• Reporter: Di Wang

Description

This test is to verify 2.5/2.7 clients can work with DNE2 servers.
For DNE2 server, it can use this build
https://build.hpdd.intel.com/job/lustre-reviews/32529/

2.5/2.7 client can use the most update rpm in the build.
https://build.hpdd.intel.com

Right now, we can check these two things.

1. Sanity should pass as other inter-op test.
2. check if "lfs mkdir" and "lfs mv" works in this environment.

Fix was landed for 2.8

[Lai Siyao]

Jian, yes, you're right.

Hi James,

Lustre 2.7 and 2.5 do not contain the patch http://review.whamcloud.com/12282 for LU-3537, which introduced the issue. So, we do not need back-port http://review.whamcloud.com/15323.

Di or Lai, could you please confirm on this?

[James A Simmons]

Don't we need to back port it to 2.7 and 2.5?

Lai - Have you had a chance to to verify now that the patch has landed?

Richard, you may wait for some time, cause when all patches landed, I'd like to test again to verify.

[Richard Henwood (Inactive)]

Lai,

Can this ticket be closed?

[Lai Siyao]

yes, Andreas.

I'll do it later.

[Andreas Dilger]

Lai, to confirm - the test failures in your last comment are when runnin with patch 15323 applied, and without that patch there are more failures due to -EREMOTE being returned to the client?

It might be useful to submit patches to b2_5_fe and b2_7_fe to skip the SOM test 132.
