3.3 Partition Configuration Data

The GFS Local File System can consist of multiple partitions. The partition configuration information area contains information on the partitions that constitute the file system and information on the area allocation in each partition.

When the GFS Local File System is shared by multiple nodes, device information for identifying each of the nodes is recorded in this area. The sfxadm(1M), sfxadd(1M), or sfxnode(1M) commands can be used when the information in this area needs to be changed.

Similar to the super block, the partition configuration information, which is also important for file system operation, is copied at the end of the partition, so that the system remains operable in the event of a disk block failure.
