Hi,
In the meantime I already tried with upgrading the cluster to 0.84, to
see if that made a difference, and it seems it does.
I can't reproduce the crashing osds by doing a 'rados -p ecdata ls' anymore.
But now the cluster detect it is inconsistent:
cluster 82766e04-585b-49a6-a0ac-c13d9ffd0a7d
health HEALTH_ERR 40 pgs inconsistent; 40 scrub errors; too
few pgs per osd (4 < min 20); mon.ceph002 low disk space

I tried to do ceph pg repair for all the inconsistent pgs:

I let it recovering through the night, but this morning the mons were
all gone, nothing to see in the log files.. The osds were all still up!

I restarted the monitors now, I will let you know when I see something more..
