ls: Service Data 1: Device not configured
"Device not configured" is a strange error for a simple
ls command.
Usually a bad mount turns up as a basic directory... but that one seems to be in some state of limbo (somewhere between a mount and a folder).
When things get tricky, I normally like to see more info than the ordinary
-la options (such as ACLs, flags, xattrs and even inode numbers). Given the strange error you got, i don't expect this to work... but i would've liked to have seen:
ls -Orbitlake@ /Volumes
Your prompt being
$ tells me you weren't in a root shell... so chances are that
sudo was probably needed for
rm to work. But again, that "Device not configured" is not something i've ever had to deal with before.
It may have been useful to see these two commands as well:
df -h
mount
