Thank you very much for working on MDS issues, your work gave me some
hope that our very long standing crashes at MDS failover could be fixed
soon.
Right now, we have our four node test cluster running with 0.55 and your
latest patches. Hopefully, today's stress test will work fine.
One question: with your latest patches, is a multiple MDS setup stable
in your tests? So far, we only tried with max mds = 1. As our work load
writes many small files, some load sharing for MDS would be nice to
have. I would be willing to help with tests and reports, if needed.
