Please consider adding /lib/udev/rules.d/50-rbd.rules: KERNEL=="rbd[0-9]*", ENV{DEVTYPE}=="disk", PROGRAM="/usr/bin/ceph-rbdnamer %k",$ KERNEL=="rbd[0-9]*", ENV{DEVTYPE}=="partition", PROGRAM="/usr/bin/ceph-rbdnamer$ This allows the rbd device to be access via a consistent name in /dev rather than a variable /dev/rbdX one. Reproducible: Always
