This issue relates to the following test suite run: http://maloo.whamcloud.com/test_sets/6c173a68-3e61-11e3-9906-52540035b04c.

The sub-test test_184d failed with the following error:

swap /mnt/lustre/d0.sanity/d184/f.sanity.184d-1 /mnt/lustre/d0.sanity/d184/f.sanity.184d-2 layouts failed

After rolling downgrade servers and clients from 2.5.0 to 2.4.1, run sanity test, hit following error
