Quotes of the week

Indeed, Linux/Sistina LVM/LVM2 just omit LV mirroring (lvconvert -m), as well as a facility
for online filesystem&LV resizing (fsadm was there in LVM1, but not in LVM2). LV mirroring is
present in Veritas LVM (Solaris, HP-UX) after which Sistina's one was modelled, as well as in
IBM (AIX, OS/2) LVM. Under Linux, I still have to create lower-level mirror by mdadm, then LVM
PV over it.
