The multipath-tools FAQ has the following to say about partitioning
multipath devices.

I take this to mean, for example, that one should partition /dev/sdX,
rather than the corresponding coalesced /dev/mapper/... device, correct?
My question is: why? Paritioning the /dev/mapper device appears to
work. Is there an operational difference? I've always done this
exactly as advised, but I know someone who didn't, and we're wondering
if it matters.
TIA
