EXAMPLES

Use

mkfs to create a VxFS ﬁle system on /dev/rdsk/c0t6d0

mkfs -F vxfs /dev/rdsk/c0t6d0 1024

Use mkfs to determine the command that was used to create the VxFS ﬁle system on

/dev/rdsk/c0t6d0

mkfs -F vxfs -m /dev/rdsk/c0t6d0

Create a VxFS ﬁle system on /dev/vgqa/lvol1

, with a Version 4 disk layout and largeﬁles capability:

mkfs -F vxfs -o version=4,largefiles /dev/vgqa/lvol1

WARNINGS

If you want to reuse a special device that was previously used by LVM, you must ﬁrst wipe out all the

LVM information remaining on the disk. Use pvremove(1M) to remove the LVM information before exe-

cuting mkfs_vxfs (1M). (You can also remove the LVM information by initializing the device with

mediainit (1), but that is slower.)

The

-o largefiles option should be used with care, since older applications do not react correctly

when confronted with large ﬁles.
