Hi,

Is it possible to have cephadm managed containers to repair their BlueSTore metadata? So to have it perform a ceph-bluestore-tool repair --path /var/lib/ceph/osd/$osd inside the container? And for that matter, be able to  "compact" (ceph-kvstore-tool bluestore-kv /var/lib/ceph/osd/ceph-$osd) beforehand (to speed up the repair process afterwards). This to allow BlueStore to handle per PG OMAP metadata.

I finally found "Calling miscellaneous ceph tools" information in the "troubleshooting" section ...

cephadm unit --name osd.$id stop
cephadm shell --name osd.$id

Now you are able to perform all the commands while the daemon is stopped (and a new container with bash shell is started for you).

Still it would be really helpfull to have cephadm orchestrate this, preferably with the option to have a couple of tasks executed in a certain order.
