You can, but I'd not run cplv on a mounted filesystem, as you can get
corruption. Run cplv on a closed (unmounted) lv.

Sure thing -- what you want to do is tell the system there is already
a filesystem there, and once it knows that it will be able to mount
it.

So....

first, you umount the old one, then cplv the LV portion of the fs
while it is not being used. You got that already, so the next step...

Check the new VG and find the loglv. Keep that name.

Now, vi /etc/filesystems and look for your fs. Change the LV name and
loglv name in the stanza to reflect the new lv. Save the file and
exit.

You should be able to mount the fs now. When it works, rmlv the old
lv, and you'll be clean.
