11.5.3.1 Adding node information

Described below is the procedure for using sfcnode(1M) to add node information (moony) to an existing file system (/dev/sfdsk/gfs01/rdsk/volume01). Execute the command on any one of the nodes where the file system is shared.

1. Check that the target file system is unmounted on all nodes sharing the file system.

You can do this by checking that "STOP" is displayed in all status fields of the sfcinfo(1M) outputs.

# sfcinfo -n /dev/sfdsk/gfs01/dsk/volume01 <Enter>
/dev/sfdsk/gfs01/dsk/volume01:
FSID  hostID    status  hostname
   1  80a4f75b  STOP    sunny

2. Add the node information.

# sfcnode -a moony /dev/sfdsk/gfs01/rdsk/volume01 <Enter>

3. Confirm that the node information has been added.

You can do this by checking that the moony field is newly displayed.

# sfcinfo -n /dev/sfdsk/gfs01/dsk/volume01 <Enter>
/dev/sfdsk/gfs01/dsk/volume01:
FSID  hostID    status  hostname
   1  80a4f75b  STOP    sunny
   1  80960096  STOP    moony

4. Set the added node as MDS node.

# sfcadm -g ,moony /dev/sfdsk/gfs01/rdsk/volume01 <Enter>

5. Check if the node to the node where an MDS is configured has been added.

If moony is displayed as MDS(S), the node has been added.

# sfcrscinfo -m /dev/sfdsk/gfs01/rdsk/volume01 <Enter>
/dev/sfdsk/gfs01/dsk/volume01:
FSID  MDS/AC  STATE  S-STATE   RID-1   RID-2   RID-N  hostname
   1  MDS(P)  stop   -             0       0       0  sunny
   1  AC      stop   -             0       0       0  sunny
   1  MDS(S)  stop   -             0       0       0  moony
   1  AC      stop   -             0       0       0  moony
