(lib)parted does not link to dmraid; it contains its own code to generate the name by always adding the 'p' in libparted/arch/linux.c. > GParted uses (lib)parted to come up with device names, except in the > case of dmraid devices.

It shouldn't be using both dmraid and kpartx to create the partition devices. If dmraid does it, then calling kpartx at best does nothing, and at worst creates duplicate devices. -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
