Veritas™ File System 5.0.1 Administrator's Guide

Encapsulate dbvol:

# fsvoladm encapsulate /mnt1/dbfile dbvol 100m

# ls -l /mnt1/dbfile

-rw------- 1 root other 104857600 May 22 11:30 /mnt1/dbfile

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.

VOLUME INDEX LENGTH STATE CONTEXT

vol1 0 102400 ACTIVE -

vol2 1 102400 ACTIVE -

dbvol 2 102400 ACTIVE -

The volume set has three volumes.

Deencapsulate dbvol:

# fsvoladm deencapsulate /mnt1/dbfile
