This is not possible. A filesystem must be shrunk before the underlying storage device. If you shrink the LV first then portions of the filesystem will now map to non-existent sectors. If files exist in those sectors they will be lost. Same goes for filesystem metadata. It is possible to add sectors to a device under a mounted filesystem because the filesystem has no knowledge of them, and is not mapping them. The same is not true of removing sectors under a mounted filesystem, for the reason above. Cheers, Stan -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
