15.2.8 For future expansion

When the GFS Shared File System is created with sfcnewfs(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 -l maxvol parameter of sfcnewfs. 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.

As needed for future file system expansion, set larger than the default values for options, such as maximum number of partitions, to create a file system with sufficient disk space allocation.

sfcnewfs parameter	Default	Meaning
maxdsz(-d)	File data area size at specification	Maximum file data area size
maxnode(-n)	16	Maximum number of sharing nodes
maxvol(-l)	16	Maximum number of partitions
