Hi All,
I upgraded my remote boot server to a new machine running ubuntu 20.04, and
although I tried to set everything up the same for remote booting the
ROACH2s, the process fails as shown in the attached file because the root
file system could not be mounted. I found one suggestion on the web to
edit the Linux/PPC load configuration to add vers=4,tcp to the line, i.e.
it might look like this:
root=/dev/nfs nfsroot=192.100.16.206:/srv/roach2_boot/etch,vers=4,tcp
ip=dhcp
but I cannot find any file where that configuration is set. There is a
file in /srv/roach2_boot called pxelinux.cfg that looks promising, but it
is an empty file. Am I on the right track?
Any suggestions?
Thanks,
Dale
