    Description

      We need an automated test to exercise adding OSTs and MDTs online to a live filesystem that is under load.

      Andreas provided this guidance:

      Add a conf-sanity test to format MDTs and OSTs, mount the first half of them, start a workload (eg. "rsync -a /etc /usr/lib $DIR/$tdir"), and then mount the second half of MDTs and OSTs).

      You can likely copy test_46a to test_46b and add in the rsync workload instead of waiting nicely for the second set of OSTs to be added.

            The test runs on Autotest showed much more chance of hitting the object-on-new-OST creation race, with a long list of files being created on new OSTs:

:

            and the client console logs showing this error was hit for each new OST addition.

            This is likely because there are more Autotest OSTs to be added (6) instead of Janitor (only 1):

            It looks like the test case has exposed an expected failure case where the MDS created a file with an object on the newly-added OST but the client wasn't aware of the new OST yet:

            Issue LU-17334 is tracking the fix for client gracefully handling of this case, while LU-17300 is tracking the fix to avoid creating such files in the first place. Both fixes are useful to implement for interop and reliability reasons.
