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

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
