I'm trying to install a machine via kickstart from another box via
nfs. I'm running into a problem that the node I'm installing can't
talk to the nfs server because it drops the 9000 byte packets from the
nfs server because it has the default mtu of 1500. It was suggested
in rfc 1191 that if you specify a smaller block size than the mtu then
the server will not send these large packets and the install can
complete. So my question is how do I pass the rsize and wsize options
to the installer?
Shouldn't your switch detect that the client cannot handle the 9000-byte
MTU and break the packets up into the standard 1500? We've had open
support requests with Red Hat regarding setting the MTU during
kickstart. RHEL 3 U6 and RHEL 4 U2 (both in beta) have this
functionality, but we've not tested it yet.
