The GFS Shared File System has a multi-partition configuration. Any of the partitions may consist of one or more partitions which can be allocated to one file system.
In a single partition configuration, an update log area, a meta-data area, and a file data area are allocated to one partition.
Examples of multi-partition configurations are shown on the following pages.
1. Separating the update log area to a separate partition (update log partition separation)
2. Adding a file data area to another partition. (file data area addition)
3. Multi-partition configuration with update log area separation and file data area addition
4. Partition configuration in which the file data area is separated from the representative partition.
5. Partition configuration in which the meta-data area, update log area, and file data area are independent.
6. Partition configuration in which the meta-data area, update log area, and multiple file data areas are independent.
7. Adding the meta-data area to another partition. (meta-data area addition)
8. Adding a meta-data area and file data area to another partition. (meta-data area and file data area addition)
9. Multi-partition configuration with update log area separation and meta-data area addition
10. Multi-partition configuration with update log area separation and meta-data area addition and file data area separation.
In a multi-partition configuration, super block
and partition configuration data are maintained in all partitions.
