Description

When invoking smartctl on mon devices, the device name is empty:

ceph : user NOT in sudoers ; TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/sbin/smartctl -a --json=o /dev/

Also, mon devices are not listed in `ceph device ls` output.

If `ceph-mon` runs as a systemd unit, check if `PrivateDevices=yes` in `/lib/systemd/system/ceph-mon@.service`; if so, try setting `PrivateDevices=false` instead, then

```
  1. systemctl daemon-reload
  2. systemctl restart ceph-mon.target
    ```

If `ceph-mon` runs in a container, you might have a similar issue if the host `/dev` isn't exposed within the container.

This PR should fix it: https://github.com/ceph/ceph/pull/44221.

I'd like to backport this to Pacific and Octopus, but the Backport Bot didn't create the corresponding tickets; what needs to be done in order for this to happen?

Thanks, Benoît,
Once the status is changed to "Pending Backport" the bot should find it.

Ah, indeed! I don't think I would have been able to change the status myself though, so thanks for doing it!
