You won't loose any data, but it will be invisible or inaccessible to the applications, if any using /opt. By the way, what's the necessary for unmounting /opt ?

befor umounting
fuser -u /opt
will list u users using this file system ask them to close there work.

or
fuser -k /opt
will kill everything related to file system /opt.

in any case data loss is not possiblem.

It seems unlikely to me that you will be able to unmount /opt unless you re-boot into single user mode.

Just something to keep in mind.

You can't umount the /opt in multiuser mode.

In single user mode u can mount the required LV and execute the maintenance task.
