Looks like it needs to get the open file count from all of the stripes' MDTs.

Comment by Andreas Dilger [ 03/Feb/14 ]

Girish, could you please take a look at this. The test needs to be updated to add up the open count from all of the MDTs if the directory is created with multiple stripes. It should be possible to just use "do_facets" and "calc_sum" to get the open count from all MDTs and add them up. In the non-DNE case, or without striped directories the count on the other MDTs will be zero.

Girish, will you be able to look at this? I think it is a simple test script problem when running in DNE mode because it is not checking all the MDTs for open files.

Yes, Swapnil will take it up.

I've pushed http://review.whamcloud.com/10107 as an untested attempt to fix this bug, which is a 2.6 blocker. Hopefully it will pass, but if not someone else will need to finish it off.

Swapnil, can you please investigate this test failure and see why it is not passing?
