When a GFS Shared File System is created with sfcmkfs(8), the file system is configured, considered for future expansion by default. Check the parameter values in the following table and see if they are sufficient for the future expansion. For example, the partition addition function cannot add partitions exceeding the -o maxvol parameter of sfcmkfs(8). 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.
sfcmkfs(8) 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 |
