It may be mirrored, but to boot from the mirrored lvol you must create a complete secondary boot disks (using pvcreate -B and then after having created the mirrors running lvlnboot). In my opinion, mirroring should be made a part of the LVM because then the LVM will be in complete control of the mirrors, which allows other nice things such as lvsplit/lvmerge and others. ++Jos Denis JARRIL wrote: > > I don't agree. > With HP-UX, you can boot from anywhere.
