mkcephfs failing on v0.48 "argonaut"

[Paul Pettigrew <Paul.Pettigrew@xxxxxxxxxxx>]

Firstly, well done guys on achieving this version milestone. I successfully upgraded to the 0.48 format uneventfully on a live (test) system.

The same system was then going through "rebuild" testing, to confirm that also worked fine.


Unfortunately, the mkcephfs command is failing:

Also fails if not forcing to use btrfs, eg:

Confirming all this was working previously, and the crushmap, config file, etc are all proven to be OK (get same failure when not specifying a custom crushmap also). Also note that whilst the above is failing on osd.0 creation, I have swapped disk references and still get the same failure on different HDD's when they are hooked in as osd.0

The setup is: Ubuntu 12.04 x64, with "main/release" ceph installed per: http://ceph.com/docs/master/install/debian/

Many thanks!

Paul
