Did you stop the OSDs?
Zitat von Jonas Schwab <jonas.sch...@uni-wuerzburg.de>:
Thank you very much! I now stated the first step, namely "Collect the
map from each OSD host". As I have a cephadm deployment, I will have to
execute ceph-objectstore-tool within each container. Unfortunately, this
produces the error "Mount failed with '(11) Resource temporarily
unavailable'". Does anybody know how to solve this?
Best regards,
Jonas

I believe I accidentally nuked all monitor of my cluster (please don't
ask how). Is there a way to recover from this desaster? I have a cephadm
setup.
There is a procedure to recover the MON-DB from the OSDs:
