Tried [1] already, but got error. Created no osd(s) on host ceph-4; already created? The error is from [2] in deploy_osd_daemons_for_existing_osds(). Not sure what's missing. Should OSD be removed, or removed with --replace, or untouched before host reinstallation?

The case is to import OSDs after host OS reinstallation. All OSDs are SSD who has DB/WAL and data together. Did some research, but not able to find a working solution. Wondering if anyone has experiences in this? What needs to be done before host OS reinstallation and what's after? Thanks!
