Hi, Is there a portable and consistent way to figure out if a given /dev/XXX path (for instance /dev/dm-1) is a partition of a whole device ? Although checking /sys/block/dm-1/dm/name for a number at the end (like mpatha1 or mpatha2) would probably work, it feels like a fragile hack. Looking into /sys/block/dm-1/slaves will lead to /sys/block/dm-1/slaves/dm-0 and we can check that /sys/block/dm-*/subsystem is class/block. But that does not necessarily mean dm-1 is a partition of dm-0, just that it's a slave of dm-0.
Any idea ? Cheers -- Loïc Dachary, Artisan Logiciel Libre
