Determining a File System's Type

These commands work whether or not the file system is mounted.

If you have the raw device name of a disk slice, you can use the fstyp or the df command to determine a file system's type. For more information, see fstyp (1M) or df (1M) .

The following example uses the fstyp command to determine the file system type.

# fstyp /dev/rdsk/c0t0d0s0
zfs

The following example uses the df –n command to display a system's file system types.

# df -n
