9.2.2.3 Customizing the GFS Shared File System

Parameters for customizing a file system are provided by sycmkfs(8), which creates a GFS Shared File System. Typical parameters are described below.

Update log area size (-o logsz=n)

This parameter specifies the size of the update log area with a value in the range from 5 to 100 megabytes. The default value is 1% of the file system size. If, however, 1% of the file system size is smaller than 5 megabytes, 5 megabytes is set. Also, if it is larger than 50 megabytes, 50 megabytes is set.

Meta-data area size (-o metasz=n)

This parameter specifies the size of the meta-data area in the representative partition. The default value is about 10% of the file system size. When the meta-data area size is not specified, the larger the file system size is, the smaller meta-data area is used.
