4.2.5 For future expansion

When a GFS Shared File System is created with mkfs_sfcfs(1M), the required minimum area is allocated according to the default settings. At file system creation, check that at least the parameter values listed in the table below are sufficient for future expansion. For example, the partition addition function cannot add partitions exceeding the -o maxvol parameter of mkfs_sfcfs(1M). In this case, to expand the file system, the current data must be backed up and then deleted, a new file system must be created, and the data must be restored.

In preparation for file system capacity expansion for future needs, create a file system, estimating the maximum size for expansion.

[Table Parameter that you should confirm for future expansion]

mkfs_sfcfs(1M) parameter	Default	Meaning
maxdsz	File data area size at specification	Maximum file data area size
maxnode	16	Maximum number of sharing nodes
maxvol	16	Maximum number of partitions
