I'm in 3-replication, DC building as failure domain.
Currently each DC has 1-2 hosts, and each host has ~10 OSDs.

Thanks, I'll try that next time it happens!
Hmm, we have similar (but larger) setups. We don't have misplaced
objects after a node reboot, only degraded. Note that we have an even
number of hosts in each DC. I also would not expect any misplaced
objects (when OSDs do not get marked "out") at all. So I wonder how your
CRUSH rule(s) look like, and if the DC placement CRUSH rule(s) are
applied on all the pools. Can you provide your crush rules?
ceph osd crush rule dump
Example:
<snip>
"op": "chooseleaf_firstn",
"num": 0,
"type": "datacenter"
<snap>
