Right now, we have our four node test cluster running with 0.55 and you= r 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 =3D 1. As our work lo= ad 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.
