$ /sbin/acfsutil registry -d /acfsmounts/acfs1
If you deregister a file system, then you must explicitly mount the file system after Oracle Clusterware or the system is restarted.
For example, you can dismount a file system and run
fsck to check the file system.
# /bin/umount /acfsmounts/acfs1 # /sbin/fsck -a -v -y -t acfs /dev/asm/volume1-123
After you dismount a file system, you must explicitly mount the file system.
# /bin/umount /acfsmounts/acfs1
After a file system is dismounted, you can disable the volume and remove the volume device file.
ASMCMD> voldisable -G data volume1
Dismounting the file system and disabling a volume does not destroy data in the file system. You can enable the volume and mount the file system to access the existing data. For information about
volenable, see Managing Oracle ADVM with ASMCMD .
