cp -p /shared/.localdb.backup /shared/.localdb Or use a known good copy from the other unit (in a cluster). If no backup exists:
bigstart status localdbmgr tmsh show sys service From active unit: f5 localdbmgr down
tmsh run cm sync-all tmsh show cm failover-status If localdbmgr still won’t stay up: cp -p /shared/
