If you want to give it a try, just create a snapshot on a specific device And change all the blocks on the origin, there you are, you now have a cow device containing all data needed. How to move this snapshot device to another server, reattach it to an empty lv volume as a snapshot. lvconvert -s, command requires an argument of an existing snapshot volume name. But there is no snapshot on the new server, so it can't re-attach the volume. So what procedures should be invoked to create just the detached references in LVM, so that the lvconver -s command can work?
Just copy the snapshot to another server, by whatever method you would use to copy the COW and Data volumes (I prefer partclone for supported filesystems). No need for lvconvert. You are trying WAY WAY too hard. Are you by any chance trying to create an incremental backup system based on lvm snapshot COW? If so, say so. _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://listman.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
