i saw that (i stumbled upon the thread when i head the initial
problem.
as i wrote in my initial mail, i then also upgraded the other two
noeds (carefully checking that i had disabled HA on all VMs as to
not run into problems fencing a node during the upgrade by
accident).

here is the complete output for the two other noeds:

please note that this was the upgrade from pve 4.1 to 4.2 yesterday,
as i pushed it back a bit because of the reports about problems with

(i did not yet install the ceph upgrad the seems to have been pushed
to the mirror today, as i wanted to have the cluster in a working
