Re: [suse-autoinstall] Cannot mount NFS repository automatically ? SOLVED (maybe)
The problem has just been solved, apparently The server is fitted with a bcm5700 card, which takes a lot of time to come up (more than 40 seconds) probably because of un-optimized switch settings. That timeout is too long for linuxrc to get the network and map the NFS server. However, after a while when the network finally comes up, the NFS volume *can* be mounted and the manual install proceed, as long as one answers "no" when prompted to reconfigure the NIC by linuxrc ("Your network is already configured. Do you want to change this ?") Otherwise, should one answer "yes I want to change my settings" , it looks like linuxrc would switch down and reconfig the NIC, thereby inducing another delay and screw up the NFS mount again.

It might help to a) disable autonegotiation for the card and b) extend dhcp timeout if the problem occurs during the inital setup. Both can be set in the info file (see http://www.suse.de/~nashif/autoinstall/9.0/html/x1808.html). For a), you can e.g. specify this in the info file: insmod bcm5700 line_speed=100 auto_speed=0 full_duplex=1 and you can add the same parameters in the /etc/modules.conf. We had the problem already back in autoyast1 with SuSE 7.3 where the inital dhcp request during installation after booting from network would fail because the card went down before it got an answer. Using the parameters above speeded up the answer from the switch a lot. For b) the interesting parameters are: BOOTPWait BOOTPTimeout DHCPTimeout TFTPTimeout cu, Frank -- Dipl.-Inform.
