Linking this to Layout Swapping ticket.

This is a problem of test script where it copied too much data exceeding the file size of ref2. I will fix it.

The landed patch did not really work, the tests are still failing, e.g. see

Obviously this is due to a different issue:

For unknown reason it couldn't open the file for layout swap.

Filed LU-2918 for this failure.

[Andreas Dilger]

sanity.sh test_184c is still being skipped on ZFS filesystems due to this bug. If it was fixed by LU-2918 then a patch should be submitted to re-enable the test.

[Andreas Dilger]

Saurabh, could you please submit a patch to remove test 184c from the ALWAYS_EXCEPT list in sanity.sh, with the appropriate Test-Parameters: line to run sanity several times on ZFS to ensure that it is passing reliably.
