PRIMECLUSTER Global File Services Configuration and Administration Guide 4.1 (Solaris(TM) 10 Operating System)

2.1.2 Partition configuration data

The partition configuration information contains the following information:

• What partitions are used to configure a file system. A GFS Shared File System can consist of multiple partitions.
• Area allocation in the partition

In order to expand the file system configuration and change the shared device information, the partition area will be changed.

Similar to the super block, the partition configuration data is important for operation of the file system and is designed to have a partition copy at the end of the file system and to be resistant to disk device block failures.
