Hi all, I'm running a 15.2.8 cluster using ceph orch with all daemons adopted to cephadm. I tried reinstall an OSD node. Is there a way to make ceph orch/cephadm activate the devices on this node again, ideally automatically? I tried running `cephadm ceph-volume -- lvm activate --all` but this has an error related to dmcrypt:

The OSDs are encrypted indeed. `cephadm ceph-volume lvm list` and `cephadm shell ceph -s` run just fine, and if I run ceph-volume directly, the same command works, but then of course the daemons are started in the legacy way again, not in containers. Is there another way trough the 'ceph orch' to achieve this? Or if `cephadm ceph-volume -- lvm activate --all` would be the way to go here, I'm probably seeing a bug here ? Thanks!! Kenneth
