Veritas File System 5.0 Administrator's Guide (September 2006)

3
Create a file system on the volume set:
# mkfs -F vxfs /dev/vx/rdsk/rootdg/myvset
version 7 layout
204800 sectors, 102400 blocks of size 1024,
log size 1024 blocks
largefiles supported
4
Mount the volume set:
# mount -F vxfs /dev/vx/dsk/rootdg/myvset /mnt1
5
Add the new volume to the volume set:
# vxvset addvol myvset dbvol
6
Encapsulate dbvol:
# fsvoladm encapsulate /mnt1/dbfile dbvol 100m
# ls -l /mnt1/dbfile
-rw------- 1 root other 104857600 May 22 11:30 /mnt1/dbfile
7
Examine the contents of dbfile to see that it can be accessed as a file:
# head -2 /mnt1/dbfile
root:x:0:1:Super-User:/:/sbin/sh
daemon:x:1:1::/:
The passwd file that was written to the raw volume is now visible in the new
file.
Note: If the encapsulated file is changed in any way, such as if the file is
extended, truncated, or moved with an allocation policy or resized volume,
or the volume is encapsulated with a bias, the file cannot be de-encapsulated.
Deencapsulating a volume
The following example illustrates how to deencapsulate a volume.
