Hi again, I'm still wondering if I misunderstand some of the ceph concepts. Let's assume the choose_tries value is too low and ceph can't find enough OSDs for the remapping. I would expect that there are some PG chunks in remapping state or unknown or whatever, but why would it affect the otherwise healthy cluster in such a way? Even if ceph doesn't know where to put some of the chunks, I wouldn't expect inactive PGs and have a service interruption. What am I missing here? Thanks, Eugen Zitat von Eugen Block <eblock@nde.ag>:
Thanks, Konstantin. It's been a while since I was last bitten by the choose_tries being too low... Unfortunately, I won't be able to verify that... But I'll definitely keep that in mind, or least I'll try to. :-D
Thanks!

I think you should try to increase set_choose_tries to 200 Last year we had an Pacific EC 8+2 deployment of 10 racks. And even with 50 hosts, the value of 100 not worked for us
