I have been using diskless mythbuntu (based on ltsp) for several years. After upgrading from Ubuntu 11.04 -> 11.10, nbd mounting has stopped working from the front ends.
The nbd version is 2.9.23
The kernel version is 3.0.0
In /var/log/syslog on the server I get the error "nbd0: Wrong magic (0x25609513)".
nbd-server is configured to use inetd using port 2000.
I have also tried stopping inetd and manually running nbd on the local server using the commands
This results in the same error.
I have tried turning on debugflags=0xfff in the nbd kernel module and building nbd-server with additional tracing but am having trouble solving the issue.
grepping the source code 0x25609513 appears to be the correct magic number
It is not clear to me if this is a kernel module issue or a nbd package issue.
If there is any additional information I can supply, please let me know
