Hi
So it might be worth checking if your new server actually exports the
NFS filesystem - "showmount -e localhost" might be a first start, but
perhaps a better approach would be to try and mount the filesystem on
a normal PC ?
Other things to try might be the "nolock" option - I am hazy on the
detail, but I don't think the roaches are running a lock manager
The roaches get their command line via uboot, which can be
interrupted, and the commandline inspected by typing "printenv". I
remember the variables being nested - so the "bootargs" variable would
contain references other ${variables}. Be careful to escape them
propery, and only use saveenv once you are sure they do what you want.
All the best and regards
marc
