Making a Filesystem From inst

Caution: When you create a filesystem, all files already on the disk partition or logical volume are destroyed. mkfs can be used from within the inst command to make filesystems. To make the Root or Usr filesystem on a system disk, you must use inst from the miniroot. There are two ways to use mkfs:

• The mkfs command on the Administrative Command Menu. The mkfs command uses default values for the mkfs command options. It chooses an EFS filesystem or an XFS filesystem based on the answer to a prompt. With no argument, the mkfs command makes the Root filesystem and, if a usr partition is present, a Usr filesystem. Other filesystems can be made by giving a device file argument to mkfs.

• From a shell. Giving the mkfs command from a shell (give the command sh, not shroot) enables you to specify the mkfs command line, including options.
