5.4.1 Re-setting of partition information

GFS Local File Systems retains partition information within the each partition so that the partition can be checked for consistency. When a GFS Local File System is restored to another partition with the following means, it is not in agreement with partition composition with actual partition information.

• Restoration to a partition different the backup origins by dd(1) command.
• The snapshot created by the snapshot function of GDS etc.

In order to protect user's data, a GFS Local File System is made not to be able to use the file system in the state that partition information and the partition composition are different like the above-mentioned and it.

When you restore a GFS Local File System to other partitions used the above-mentioned, please perform a re-setup of partition information. sfxadm(1M) performs a re-setup of partition information.

The following example shows how to perform a re-setup of partition information by sfcadm(1M) after a GFS Local File System restores to /dev/sfdsk/gfs/rdsk/vol0301, /dev/sfdsk/gfs/rdsk/vol0400, and /dev/sfdsk/gfs/rdsk/vol0500. The representative partition is /dev/sfdsk/gfs/rdsk/vol301. Please execute it by super user.

# sfxadm /dev/sfdsk/gfs/rdsk/vol0301,/dev/sfdsk/gfs/rdsk/vol0400,/dev/sfdsk/gfs/rdsk/vol0500
