Logs/debug information why the ceph connection is failing

[mo_]

Hi,

does the pve-manager dump logs or error messages somewhere, indicating why the ceph connection is failing? In the web interface I can only see a connection problem, which isnt saying much.

storage.cfg:

rbd: rbd
        monhost 192.168.178.41:6789;192.168.178.42:6789;192.168.178.43:6789
        pool rbd
        content images
        username admin

/etc/pve/priv/ceph/rbd.keyring is present
also put keyring and ceph.conf from the cluster into /etc/ceph, but I cant use rbd to check why its not connecting because the kernel is too old (needs >=3.14) to use kernel-rbd.

the ceph CLI isnt working either (on the pve host) for the same reason as kernel rbd: protocol feature mismatch, my 407ffffffff < peer 40fffffffff missing 800000000

that missing feature bit is cache pools by the way.

I think I fixed it, I noticed how for reasons that are beyond me, apt was only listing outdated ceph-common versions (arent firefly packages supposed to be in the debian stable main repository?). I had to add

deb http://ceph.com/debian-firefly/ wheezy main

and do "aptitude upgrade ceph-common"

It appears to be working in my testing setup here, but might that break anything?
