I tried this fix from another thread.
In my case(ubuntu 8.10), the problem was caused by the
ltsp-client-setup init script. I solved the issue by comenting out the
stuff about NBD
configure_nbd() {
# Restart nbd so -persist will work
nbdcmd=`pgrep -l -f "/dev/nbd0 -persist" | cut -d " " -f "2-"`
if [ -n "$nbdcmd" ]; then
nbd-client -d /dev/nbd0
sleep 0.5s
nbd-client -c /dev/nbd0
if [ "$?" = "1" ]; then
$nbdcmd
fi
fi
}
I commented out this part and got a bit further. This is the error I have
now.
Setting up LTSP client...
Disconnecting: que, disconnect, sock, done
[ 30.519994] nbd0: Receive control failed (result -32)
Kernel call returned: Broken pipe Reconnecting
Negotiation: ..size = 175556KB
Error: Ioctl/1/1.a failed: Bad file descriptor
Any clues how to fix this?
