Ceph » rbd

when trying to map a standard rbd image as a block device, the command fails with (2) No such file or directory.

I can run other rbd commands without issue, including `rbd info lun01`.

This is a ceph cluster deployed using the manual instructions on ceph.com site on a gentoo distro. As far as I can tell, it appears that this might be a udev issue, as a call to /run/udev/queue is issued, and that path doesn't exist.

here's the dmesg | tail output after running the rbd map command:

the ceph -s output:
