I have a couple of SS1+ intended to be setup as one server with a lot of=20
disk, and the others diskless.
I and a friend tried to boot one of the diskless machines via NFS from a=20
partition at the server. Everything worked ok, until the kernel was=20
loaded into memory, and tried to mount the root, then it panic'ed.
We tried to rebuild the kernel for the diskless machines (without reading=
=20
all about it, I might add). We made a stripped version, without SCSI=20
support, basically only with support for NFS_client-mounts. It didn't=20
work either (but it was small :-).
Eventually I read about "Diskless Client Support" in SMM (nfs part), and=20
figured out one have to specify mountroot to nfs_mountroot, and swdevt[0]=
=20
to NODEV. But SMM seems to be a bit out of date. None of the files=20
mentioned existed. (The documentation to config(.new) is a bit old too).
I tried to figure out how things is nowadays by searching in the=20
source-tree, but failed.
Has anyone succeded in setting up a kernel for diskless operation?
If so, how did you do it?
Where can I find more acurate documentation about NFS, config(.new) etc?
I run NetBSD1.0. (Is things better with current?)
Thanks in advance!
