Hi Ilya, ceph-disk has special handling for device names like /dev/cciss/c0d1 [1] and it was partially broken when support for device mapper was introduced. Ideally there would be a way to test that support when running the ceph-disk suite [2]. Do you know of a way to do that without having the hardware for which this driver is designed ? Maybe this convention (/dev/cciss/c0d0 being mapped to /sys/block/cciss!c0d0 is not unique to this driver and I could use another to validate the name conversion from X/Y to X!Y and vice versa is handled as it should ?
