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=
=2E Ideally there would be a way to test that support when running the ce=
ph-disk suite [2]. Do you know of a way to do that without having the har=
dware for which this driver is designed ?=20

Maybe this convention (/dev/cciss/c0d0 being mapped to /sys/block/cciss!c=
0d0 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 ?

Cheers
