Hi
I simply add the line into my config:
[osd]
osd class tmp = /var/lib/ceph/tmp
and my rbd works well.
Thanks Yehuda, and please add this option to the wiki.
what i did:
# mkdir -p /var/lib/ceph/tmp
# (add the "osd class tmp" clause into config)
# mkcephfs -c /usr/local/etc/ceph/ceph.conf --allhosts --mkbtrfs
# /etc/init.d/ceph -c /usr/local/etc/ceph/ceph.conf --allhosts start
# cclass -a
# ceph class activate rbd 1.2
# rbd -p rbd create testdata --size 128
# rados -p rbd ls

Hi
I also trying to use rbd in my environment, following the wiki's instruction.
and I did "ceph class activate rbd 1.2", but still not works.
My situation:
# mkcephfs -c /usr/local/etc/ceph/ceph.conf --allhosts --mkbtrfs
# /etc/init.d/ceph -c /usr/local/etc/ceph/ceph.conf --allhosts start
# cclass -a

This last operation never returns. What version are you using? Can you
add the corresponding osd logs?
Also, can you verify that /var/lib/ceph/tmp exists and is writable by
the user running the cosd daemon, and make sure that there is no
execution restriction there (this path can be configured by the 'osd
class tmp' config variable).
Thanks,
Yehuda
