Can you try with both cluster and osd fsid? Something like this:
pacific2:~ # cephadm deploy --name osd.2 --fsid
acbb46d6-bde3-11eb-9cf2-fa163ebb2a74 --osd-fsid
bc241cd4-e284-4c5a-aad2-5744632fc7fc
I tried to reproduce a similar scenario and found a missing config
file in the osd directory:
Error: statfs
/var/lib/ceph/acbb46d6-bde3-11eb-9cf2-fa163ebb2a74/osd.2/config: no
such file or directory
Check your syslog for more information why the osd start fails.
