11.1 When the Name of a Node Using GFS Local File System is Changed

GFS Local File System stores the name of each node that uses the file system, the respective host-ids, and information on all devices in the file system. When a node name is changed after the GFS Local File System has been created, the change must be incorporated at the required places in the GFS Local File System. Change the respective settings with the sfxnode command; otherwise, the GFS Local File System cannot be mounted.

The following steps have to taken when the node name is changed from "sunny" to "moony":

1. Check the current settings.

# sfxinfo -n /dev/sfdsk/gfs/dsk/vol0301
/dev/sfdsk/gfs/dsk/vol0301:
ID      hostID          hostname
0       807exxxx        sunny

2. Set the new node information.

# sfxnode /dev/sfdsk/gfs/rdsk/vol0301
hostid: 807exxxx         nodename: moony

3. Check the node information.

# sfxinfo -n /dev/sfdsk/gfs/dsk/vol0301
/dev/sfdsk/gfs/dsk/vol0301:
ID      hostID          hostname
0       807exxxx        moony
