Zone remains stuck in down state if tried to halt with file system mounted from global zone

Last published : Sep 23, 2026
If zone halts without unmounting the file system, the zone goes to down state and does not halt with the zoneadm commands.
Workaround: Unmount the file system manually from global zone and then halt the zone. For VxFS, use following commands to unmount the file system from global zone.
To unmount when VxFSMountLock is 1
umount -o mntunlock=VCS <zone root path>/<Mount Point>
To forcefully unmount when VxFSMountLock is 1:
\# umount -f -o mntunlock=VCS \<zone root path\>/\<Mount Point\>
To unmount when VxFSMountLock is 0:
\# umount <zone root path>/<Mount Point>
To forcefully unmount when VxFSMountLock is 0:
\# umount -f \<zone root path\>/\<Mount Point\>
To halt the zone, use following command:
\# zoneadm -z <zone_name>  halt
