3.7 Multi-partition Configuration

GFS Local File System supports not only file systems that consist only of a single partition, but also multi-partition configurations, in which two or more partitions are allocated to a single file system.

In a single partition configuration, update log, meta-data, and file data areas are all allocated in a single partition.

There are the following five patterns for multi-partition configurations:

• The update log area is reserved in a separate partition (Log area is separated).
• An additional file data area is reserved in a separate partition (Data area is adding).
• The update log area is reserved in a separate partition and an additional file data area is reserved in another file partition (Log area is separated + Data area is adding).
• A file data area is separated from the representative partition (Data area is separated).
• The meta-data area, file data area and update log area are individually independent (meta-data area, file data area, update log are separated).

Every partition contains its own super block and partition configuration information area.
