9.6.2 Deleting the file system

To delete a file system that is not being used in the GFS Shared File System, use the -D option of sfcadm(8).

For details about sfcadm(8) options, see "sfcadm(8)" in this manual.

The following shows how to delete a file system with sfcadm(8).

• Check the current file system information.

# sfcinfo -a
/dev/sfdsk/gfs/dsk/volume1:
FSID special                                  size    Type   mount
   1 /dev/sfdsk/gfs/dsk/volume1(e721)        407144   META   -----
