What you are seeing is from the lack of a index for the MDT when run from older lustre versions on the clients. We could fix this either but updating the test framework on earlier lustre to detect the lustre version on the MDS and supply a --index=0 or we could patch mkfs.lustre to automatically supply a index of zero for a MDT if no index was supplied.</p> <p>BTW I think the lack of index for MDT with older test frameworks should be a separate ticket from this.</p> <p>I will file a separated ticket for the interop issue and close this one. Thanks. </p> Related LU-3559 LU-2202 Development Rank 1|hzv3rb: Rank (Obsolete) 4132 Severity
