4.3.2 Customizing the GFS Local File System

The sfxnewfs(1M) command that is used to create a GFS Local File System contains the parameters for customizing the file system. The respective parameters are as follows:

[Size of update log area]

Specify the size of the update log area. The size that can be specified within a range from 5 to 100 megabytes. The default size is 1% of the size of the file system. However, if 1% of the file system size should be less than 5 megabytes, the value is set to 5 megabytes. If it should exceed 50 megabytes, the value is set to 50 megabytes.

[Size of meta-data area]

Specify the size of the meta-data area in the representative partition. The default is about 10% of the size of the file system. If the maximum size of file data area is specified, the default is set to about 10% of the specified size.

[Maximum size of file data area]

Specify the maximum total size of the file data area for the case that data partitions are added to the GFS Local File System. Data partitions can be added using the sfxadd(1M) command. This parameter has to be specified if data partitions are to be added. The maximum value that can be specified here is less than 1 terabytes.

[Maximum number of partitions]

Specify the maximum number of partitions that can be added to the GFS Local File System. A GFS Local File System consists of the representative partition, update log partition, and data partition(s). The maximum number that is to be specified here is the total number of these partitions. The number can range from 1 to 32. The default value is 16.

[Maximum number of sharing nodes]

Specify the maximum number of nodes that can directly share the specified GFS Local File System. This number can range from 1 to 16. The default value is 16.
