To add a partition as file data area, use sfcadd(8). Execute the command on any one of the nodes where the file system is shared.
See
For details on sfcadd(8), see sfcadd(8).
Note
If you add a partition to the file system that is not stopped properly, recovery the file system by executing the sfcfsck(8) command in advance.
How to add a file data partition (/dev/sfdsk/gfs01/dsk/volume02) to an existing file system (/dev/sfdsk/gfs01/dsk/volume01) by sfcadd(8) is shown below.
Check the configuration of the current file system.
# sfcinfo /dev/sfdsk/gfs01/dsk/volume01 <Enter> /dev/sfdsk/gfs01/dsk/volume01: FSID special size Type mount 1 /dev/sfdsk/gfs01/dsk/volume01(1e756) 14422 META ----- 1 /dev/sfdsk/gfs01/dsk/volume01(1e756) 5116 LOG ----- 1 /dev/sfdsk/gfs01/dsk/volume01(1e756) 95112 DATA ----- |
Add a file data partition (/dev/sfdsk/gfs01/dsk/volume02) as file data area.
# sfcadd -D /dev/sfdsk/gfs01/dsk/volume02 /dev/sfdsk/gfs01/dsk/volume01 <Enter> |
Confirm that the file data partition has been added.
# sfcinfo /dev/sfdsk/gfs01/dsk/volume01 <Enter> /dev/sfdsk/gfs01/dsk/volume01: FSID special size Type mount 1 /dev/sfdsk/gfs01/dsk/volume01(1e756) 14422 META ----- 1 /dev/sfdsk/gfs01/dsk/volume01(1e756) 5116 LOG ----- 1 /dev/sfdsk/gfs01/dsk/volume01(1e756) 95112 DATA ----- 1 /dev/sfdsk/gfs01/dsk/volume02(1e757) 65512 DATA ----- |
Note
To add a file data partition, be aware of the following:
A file data partition addition is not possible if doing so would exceed the maximum number of partitions (-o maxvol=n) for the file system, as specified by sfcmkfs(8).
When file system's file data area size after adding partition exceeds the maximum file data area size specified by sfcmkfs(8) (-o maxdsz=n), a part of free area in file data area might not be able to be used because of management region shortage.
