All of the metadata needed to reconstruct the VG is on the physical disk itself. The only time you need anything from /etc/lvm/ is when any of that gets damaged and needs to be rewritten. > If we have a recovery server pointed to the mirrored volume, > will it see the LVM metadata?

See "man lvcreate" for the -m/--mirrors option. Either way, I don't see any reason why you shouldn't use the SVC itself to mirror the disk(s).
