 Description   

This issue was created by maloo for S Buisson <sbuisson@ddn.com>

This issue relates to the following test suite run: https://testing.whamcloud.com/test_sets/f6d4f1f8-22ae-11ea-971c-52540065bddc

test_47b failed with the following error:

create must fail

I am wondering if all sanityn tests 47 are robust enough in case MDT0001 is on secondary MDS. Indeed, fail_loc is set on SINGLEMDS, which means primary MDS, whereas directory is created with 'lfs mkdir -i 1', so on secondary MDS in the context of review-dne-zfs-part-1, that has:

  • MDS 1, MDS 3 on 1st MDS;
  • MDS 2, MDS 4 on 2nd MDS.

It would be great if you can fix this test with a simple change but fails pretty regularly.

Comment by Andreas Dilger [ 20/Dec/19 ]

Is the fix just a matter of setting the fail_loc on all MDS nodes?

Comment by Sebastien Buisson [ 06/Jan/20 ]

My understanding is that the fail_loc should be set on all MDS nodes, if someone could confirm (it seems Wang Di is the one who submitted the tests).
