Certain things somehow lock devices so that once it is in use, any further
attempt to access that device gives the above message. I had the same message
when playing around with additional swap space. I've also seen it when playing
with the tape unit (/dev/rmt0h & Co.). My guess is that something in the
kernel already has your swap devices open in an exclusive mode and any further
references give the somewhat misleading message about `no such device' when it
might be better to spit out `device locked' or something like that.
On the other hand, I'm speaking from intuition, not knowledge, so maybe
somebody should correct what I just said.
