Hi guys,
I had a functioning Ceph system that reported HEALTH_OK. It was running
with 3 osds on 3 servers.
Then I added an extra osd on 1 of the servers using the commands from
the documentation here:
http://ceph.com/docs/master/rados/operations/add-or-rm-osds/
Shortly after I did that 2 of the existing osds crashed.
I restarted them and after some hours they were up and running again,
but soon one of them crashed again - and a third existing osd crashed as
well. I restarted those two and waited some hours for them to come up. A
short while later one of them crashed again.
I have then restarted restarted that last one and watched the logs
closely. It seems the same patterns repeats itself every time. It starts
up doing its normal maintenance before going "up" (takes a long while).
Then it seems to be running, but logs the following every 5 seconds:
heartbeat_map is_healthy 'OSD::op_tp thread 0x7f051b7f6700' had timed
out after 30
After some time it logs:
===================================================

timed out after 300

===================================================
How can I avoid this? - is it a bug, or have I done something wrong?
I'm running Ceph 0.56.1 from the official RPMs on Fedora 17.
The underlying disks and network connectivity has been tested and
nothing seems to be wrong there.
Thanks in advance for your assistance!
