Is this what you are looking for:

Anyway, i removed the mon and did a ceph-mon --mkfs with the 3 mons that were
still working after the upgrade and got it up and running again.
Yes, the cluster is still working after the upgrade. Also upgraded to linux
3.4.4 - it feels like the ceph-fuse and kernel ceph client is a little less
robust than in 0.43...
when i start copying from /ceph to other mp, then it seems that for the copy
operation or in general for any operation, /ceph is unusable to other processes
which then makes the client behave very sluggish... :(
i can send you the contents of the monitor directory where it did not work after
the upgrade if you want me to..
