22.9.2 Deleting the file system

To delete a file system that is not being used in the GFS Shared File System, use sfcadm(1M) with the -D option specified.

For details on the sfcadm(1M) options, see Appendix F.2.2, "sfcadm(1M)."

How to delete a file system using sfcadm(1M) is shown below.

1. Check the current file system information.

# sfcinfo -a
/dev/sfdsk/gfs/dsk/volume1:
FSID special                                     size   Type   mount
   1 /dev/sfdsk/gfs/dsk/volume1(3fa0081)        407144   META   -----
   1 /dev/sfdsk/gfs/dsk/volume1(3fa0081)       3761416   DATA   -----
   1 /dev/sfdsk/gfs/dsk/volume1(3fa0081)          5120   LOG    -----
/dev/sfdsk/gfs/dsk/volume2:
FSID special                                     size   Type   mount
   2 /dev/sfdsk/gfs/dsk/volume2(3fa0082)         51394   META   -----
   2 /dev/sfdsk/gfs/dsk/volume3(3fa0083)        523776   DATA   -----
   2 /dev/sfdsk/gfs/dsk/volume4(3fa0084)          5237   LOG    -----

2. Delete the file system whose representative partition is /dev/sfdsk/gfs/rdsk/volume2.

# sfcadm -D /dev/sfdsk/gfs/rdsk/volume2

3. Confirm that the file system has been deleted.

# sfcinfo -a
/dev/sfdsk/gfs/dsk/volume1:
FSID special                                      size  Type  mount
   1 /dev/sfdsk/gfs/dsk/volume1(3fa0081)         407144  META  -----
   1 /dev/sfdsk/gfs/dsk/volume1(3fa0081)        3761416  DATA  -----
   1 /dev/sfdsk/gfs/dsk/volume1(3fa0081)           5120  LOG   -----
