Hi Guillaume, Tim and Adam, following up on https://github.com/ceph/ceph/pull/44012#discussion_r758377347 here on dev@. How do we properly handle GPT tables on devices that are showing up on ceph-volume inventory? TLDR: The current behavior of cephadm is to create OSDs on drives with a GPT partition table, which fails as this drive was used by the host OS. This clearly doesn't work as we need to find a better way. Tim, you mentioned that In general ignoring unavailable devices seems to be a bad idea. My idea was to hide drives with GPT tables from ceph-volume inventory, but rethinking this, I now think this won't be a good idea as well. There is still the possibility to add a special case for GPT tables in cephadm, but adding a special case in cephadmn still feels wrong to me. Are there any other alternatives? Thanks, Sebastian
