The patch in http://review.whamcloud.com/5981 needs to be back-ported to Lustre b2_1 branch.

Emoly

Are you able to take care of this one as you wrote the original patch?

Thanks

Peter

I found a problem in this test that we used 2.4 as client and 2.1 as server. I'm not sure what purpose of this kind of test, but obviously some scripts in 2.4 client can't be found or interpreted in 2.1 server.

I will check if we need version check code for lfsck test.

Similar patch for master/b24 is at http://review.whamcloud.com/#change,6494

Comment by Andreas Dilger [ 21/Oct/13 ]

Emoly, Yu Jian,
the 6494 patch has landed to master - is this problem fixed?

Comment by Jodi Levi (Inactive) [ 21/Oct/13 ]

Patches landed to master.

Lustre client build: http://build.whamcloud.com/job/lustre-master/1728/
Lustre server build: http://build.whamcloud.com/job/lustre-b2_1/219/

The failure still occurred:

rpc.sh: line 20: remove_ost_objects: command not found

Patch http://review.whamcloud.com/6454 needs to be updated and landed on Lustre b2_1 branch.

Comment by Emoly Liu [ 29/Oct/13 ]

Yujian, I saw your comment on http://review.whamcloud.com/#/c/6454 that "lfsck test on the following combinations will fail because there is no remove_ost_objects() on servers"
Lustre 2.1.6 client + 2.1.5 server
Lustre 2.1.6 client + 2.2.0 server
Lustre 2.1.6 client + 2.3.0 server

Do you think we need backport the patch for these server branches or just add version check for them?

Comment by Andreas Dilger [ 29/Oct/13 ]

I'd like to spend as little time as possible on the old lfsck, so I think just skipping the tests is enough.

Comment by Jian Yu [ 30/Oct/13 ]

Hi Emoly,
I agree with Andreas. Please update the b2_1 patch to add server version check codes.
