[LU-6661] Interop DNE2 test between DNE2 clients and 2.5/2.7 servers

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

Description

This test is to verify DNE2 clients can work with 2.5/2.7 servers.
For DNE2 client, it can use this build
https://build.hpdd.intel.com/job/lustre-reviews/32529/
2.5/2.7 server 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. Note: if DNE2 clients tries to create a striped directory on 2.5 servers. 2.5 server should return -EINVAL or EIO error, but DNE2 clients should be able to create striped directory on 2.7 servers.

Issue Links

• is duplicated by: LU-6194 Interop 2.5.3<->2.7 sanity test_162c: Value too large for defined data type
• is related to: LU-3531 DNE2: striped directory

if 27e is skipped for 2.7 server, then no other patch needed.

[Andreas Dilger]

It looks like we need a patch to skip sanity test_162c for 2.5.x servers. The 27e test should also be skipped for a 2.7.0 server. Is there also a patch needed for master for 27e setstripe?

[Lai Siyao]

2.5 server:
162c: failed because of LU-4239, which is not backported to 2.5, and this test doesn't exist in 2.5 sanity either.

2.7 server:
27e: the sympton is `lfs setstripe` can be executed twice on a file, though the second setstripe won't take effect (it's assumed to return -EEXIST), this is because of http://review.whamcloud.com/13680 from LU-5814, which remove direct use of object LSM, and also http://review.whamcloud.com/12639 from LU-5823 which checks existed layout before setting it. The second patch is a server side change, to fix this the second patch needs to be backported to 2.7.

Hi Lai;

It looks like Autotest is failing early currently. Can you confirm that this test runs successfully on your local machine?
