  • Lock_managerによってSFO(ストレージフェイルオーバー)が拒否されたため、ノードが部分的なギブバック状態になっています

        aggr_node1     Failed: Operation was vetoed by
                 lock_manager.
Giveback failed during lock
                 manager veto checks or the pre-commit phase.
                 For veto failures, use the "vserver cifs
                 session file show -hosting-aggregate
                 <aggregate list> -continously-available No"
                 command to view the open files that have
                 CIFS sessions with non-CA locks established.
                 <aggregate list> is the list of aggregates
                 sent home as a result of the giveback
                 operation. If lock state disruption for all
                 existing non-CA locks is acceptable, retry
                 the giveback operation by specifying
                 "-override-vetoes true". Warning: Overriding
                 vetoes to perform a giveback can be
                 disruptive. For pre-commit failure, search
                 for the lmgr.precommit.oplock.recall EMS
                 variant for information on how to proceed
                 using the "event log show -event
                 lmgr.precommit.oplock.recall.*" command. If
                 the error persists, contact technical
                 support for assistance.
