Thanks,
Now another question, is the ceph-kclient 0.19.1 compatible with ceph
0.20, or do I have to use latest 2.6.34rc kernel ?
ceph-kclient 0.19.1 completely froze my pc...

Hi,
your journal file should either be a block device, or you have to set
the journal size in the [osd] section in ceph.conf:
osd journal size = 100
Creation sould run flawlessly then.
