Hi all,
We're trying to mount an rbd image inside of a linux container that has been created with docker (https://www.docker.io/). We seem to have access to the rbd kernel module from inside the container:
# lsmod | grep ceph
libceph 218854 1 rbd
libcrc32c 12603 3 xfs,libceph,dm_persistent_data
And we can query the pool for available rbds and create rbds from inside the container:
# rbd -p dockers --id dockers --keyring /etc/ceph/ceph.client.dockers.keyring create lxctest --size 51200
# rbd -p dockers --id dockers --keyring /etc/ceph/ceph.client.dockers.keyring ls
lxctest
But for some reason, we can't seem to map the device to the container:
# rbd -p dockers --id dockers --keyring /etc/ceph/ceph.client.dockers.keyring map lxctest
rbd: add failed: (22) Invalid argument
I don't see anything particularly interesting in dmesg or messages on either the container or the host box. Any ideas on how to troubleshoot this?
Thanks!
