Hello. We have lustre 2.15.4 on Rocky 8.9 Two MDS with ZFS backend. After some time doing snapshots writing barrier stuck in failed state.
Filesystem seems like working but I can't take snapshots anymore. barrier_thaw or rescan throw error "Invalid argument" and "-b off" option for snapshot_create have no effect. lsnapshot.log say that I call snapshot creation with barrier ON even if I say to not use it. How can I find what caused failed state to prevent that in future and is it possible to unlock?
