Description

The code is passing a wwn-* wildcard inside a string to remote.run. It's never going to get expanded so this always fails: the wwn code is effectively dead as a result.

It's from this pretty ancient commit:

commit 8f720454cbb536ac6f410fb6c18b2b0945b70160

    Assign devices to osds using the device wwn

    Linux doesn't guarantee device names (/dev/sdb, etc.)
    are always mapped to the same disk.  Instead of assigning
    nominal devices to osds, we map devices by their wwn
    (/dev/disk/by-id/wwn-*) to an osd (both data and journal).
