Is there a specific character limit for rbd block devices? In attempting to map a block device with a name that is 36 characters or more, I am getting the following error: rbd map (36+ character name) --user admin --secret /etc/ceph/keyring.key add failed: (2) No such file or directory When using the same command to map a device with 35 characters or less, the device is mapped as expected. Any insight into this issue would be greatly appreciated. -Brady
