Since it's a separate LV, it's perfectly possible that, if dm-snapshot is not available in the initrd vgscan, you won't get that LV active, but will for the rest; later on, after the root fs is mounted read-write, vgscan runs again, and the module is available, so you get the snapshot volume up and running. This is unlike dm-mirror (assuming pvmove actually uses it), since it modifies existing volumes (e.g., the one holding the rootfs), you may need dm-mirror early in order to boot up. -- Alexandre Oliva http://www.ic.unicamp.br/~oliva/ Red Hat Compiler Engineer aoliva@{redhat.com, gcc.gnu.org} Free Software Evangelist oliva@{lsd.ic.unicamp.br, gnu.org}
