Hi all, OS=CentOS 7.5 Lustre 2.10.6
One of the OSS (one OST only) was upgraded to zfs 0.7.13, and LU-11507 forced an upgrade of Lustre to 2.12 Mounts, reconnects, recovers, but then is unusable, and the MDS reports: Lustre: 13650:0:(mdt_handler.c:5350:mdt_connect_internal()) test-MDT0000: client test-MDT0000-lwp-OST0002_UUID does not support ibits lock, either very old or an invalid client: flags 0x2041401043000020 So far I have not found any hints that these versions would not cooperate, or that I should have set a certain parameter. LU-10175 indicates that the ibits have some connection to data-on-mdt which we don't use. Any suggestions?
