------------------------------------------

| Maximum File System Size

------------------------------------------------------

Block Size | In sectors | In bytes

------------------------------------------------------

1024 bytes | 4,294,967,039 | approximately 4 TB

2048 bytes | 8,589,934,078 | approximately 8 TB

RETURN VALUE

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 executing

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.
