How to Attach a Log Device to a Transactional Volume

1. Check Prerequisites for Creating Solaris Volume Manager Components and Background Information for Transactional Volumes.

2. Unmount the UFS file system for which you want to enable logging.

3. Attach a log device to the transactional volume by using one of the following methods:

   • From the Enhanced Storage tool within the Solaris Management Console, open the Volumes node, then choose the transactional volume from the listing. Right-click the volume, and choose Properties. For more information, see the online help.

   • Use the following form of the metattach command:

     metattach master-volume logging-volume

     master-volume is the name of the transactional volume that contains the file system to be logged.

     logging-volume is the name of the volume or slice that should contain the log.

     See the metattach(1M) man page for more information.

   # metattach d1 d23

4. Remount the file system.

Example—Attaching a Log Device to a Transactional Volume

This example shows a log device, the slice (c1t1d0s1), being attached to the transactional volume d1, which is mounted on /fs2.

# umount /fs2
# metattach d1 c1t1d0s1
d1: log device d0c1t1d0s1 is attached
# mount /fs2
