Hi,
I haven't been dealing with ceph-volume too much lately, but I remember
seeing that when I have multiple DB devices on SSD and wanted to replace
only one failed drive. Although ceph-volume inventory reported the disk
as unavailable the actual create command was successful. But I don't
remember which versions were okay and which weren't, there were multiple
regressions in ceph-volume IIRC, it seems to be a very complex
structure. But apparently '... batch --report' is more reliable than
'... inventory'.
I can confirm this behaviour for 16.2.10. The disk is not seen as
available, but cephadm will recreate the OSD on the LVM according to the
spec (and that in turn invokes ceph-volume with the batch lvm command).
