Problems latest CVS source.

[Drop Box]

FWIW, I ran into this issue yesterday on a new installation (on a new set of
systems).  The issue was that max_disk_age was being exceeded, so no devices
were being returned as valid.  The monitor process, in its sql call to
update the device table, sets 'mb_asof = UNIX_TIMESTAMP()', which means the
db server sets the time for that field.  It turned out that the db server
hadn't been configured to use ntp and was about eight minutes behind.  The
default max_disk_age is five minutes, hence the no_devices error.  Not sure
if you were running into the same thing, but it's something to keep in mind.

HTH.
