Hi Boris,
The workaround we used to replace disks affected by this bug is to force
devices in the osd creation using the orchestrator without yaml specs.
VG and LV are first created manually and then we used something like this :
|ceph orch daemon add osd
<host>:data_devices=/dev/data01,db_devices=/dev/fast01/db01|
See the advanced OSD creation :

Thanks Marek, but this did not work here, because the SSDs still have other
block.db LVs on it.

The orchestrator in Ceph 19 and 20 has a bug with hybrid OSDs:

There is a patch available but it has not been merged yet.
Meanwhile, a workaround that has worked for us is:
* tell the orchestrator to delete unwanted non-hybrid OSDs _without
zapping the drives_;
* manually wipe both underlying devices, with as little time in
between the two as possible;
* explicitly tell the orchestrator to refresh its device list, so that
it sees both available drives at the same time.
