Hello,

I've a cluster of three node (two osd on each node). First I've updated on node - osd is ok and running, but ceph-mon crashed.

What does that mean... you updated a mon and an osd, and other mons and osds are not upgraded?  I think you should not start an upgraded osd before the rest of the mons are upgraded.


http://docs.ceph.com/docs/master/install/upgrading-ceph/:

We recommend upgrading in this order:

1. Ceph Deploy
2. Ceph Monitors
3. Ceph OSD Daemons
4. Ceph Metadata Servers
5. Ceph Object Gateways
   
   ... a general rule, we recommend upgrading all the daemons of a specific type (e.g., all ceph-mon daemons, all ceph-osd daemons, etc.) to ensure that they are all on the same release...
