Description

I use cephadm bootstrap ceph cluster(2 host, 1 mon, 2 mgr, 6 osd, 2 mds, 1 cephfs).
For some reason, I need reinstall host opera system,but I want retained data.
What should I do?Is there some document or guide I can follow?

I hope you still have a few MONs and MGRs left. Cause then, you can follow https://docs.ceph.com/en/latest/cephadm/osd/#activate-existing-osds

Do I need upgrade my ceph-common or docker image version from octopus v15.2.12 to pacific?
