Hi:

Create your new filesystem on your internal volume group (not vg00, I hope). Create a mountpoint for it, for example, '/dstdir'. This will be changed later.

Now copy your original filesystem data (from 'srcdir') to the new mountpoint (dstdir'). Make sure that the original filesystem isn't in use by anything. You may wish to unmount and remount it to make sure that you have stopped all activity to it before you begin to copy data.

You can copy the data in various ways. Using 'cpio', 'tar', 'cp' or 'fbackup' are all ways to perform this. With 'fbackup' you can handle largefiles and easily preserve permissions together with modification and lastaccess timestamps. It it one method I particularly like:

# cd srcdir && fbackup -i . -f - | ( cd dstdir && frecover -Xrf - )

If you elect to use 'cp', make sure that your destination is empty when you begin.

When you are done, unmount the original filesystem ('srcdir') as well as the newly copied one ('dstdir'). Rename the original filesystem mountpoint (with 'mv') to anything you like. Rename the 'dstdir' directory to that of the original filesystem. Modify your '/etc/fstab' to reflect the new device file location of your copied filesystem and mount it.

When you are satisfied with everything, you can 'lvremove' your old filesystem and its old, renamed mountpoint.

Regards!
