Regression in Rhel5.1: Networking on large systems.
Last modified: 2007-11-30 17:07:47 EST
Description of problem:
On large (128p systems) with >8 nics snap3
comes up with the interfaces having IPs from
DHCP but the network not functioning.
Version-Release number of selected component (if applicable):
snap2 works snap3 and snap4 (-44) don't.
Steps to Reproduce:
Created attachment 187621 [details]
Log after boot.
Just an update.
Binary search of patches didn't work because when I build the
kernel with my build script the problem doesn't occur, but I
confirmed that with the kernels in the snapshots it does.
I am now doing an rpmbuild to see if that kernel works and
to get a trace to see what the differences are in the build
Sigh... Nothing to do with the kernel. The problem is that
in snap3 and snap4 /etc/sysconf/network does not get a
Not sure if this is related to the number of devices or if
there is something else going on.
The system where the problems occur has 8 ports with 6 active
and 4 connected all to the same subnet:
inet addr:184.108.40.206 Bcast:220.127.116.11 Mask:255.255.255.0
inet addr:18.104.22.168 Bcast:22.214.171.124 Mask:255.255.255.0
inet addr:126.96.36.199 Bcast:188.8.131.52 Mask:255.255.255.0
inet addr:184.108.40.206 Bcast:220.127.116.11 Mask:255.255.255.0
inet addr:127.0.0.1 Mask:255.0.0.0
The following is probably a decent clue, note that /mnt/sda10 is the
root of the snap2 install:
[root@billberry1 ~]# diff -r -q /etc/sysconfig/ /mnt/sda10/etc/sysconfig/
Only in /etc/sysconfig/: dhcpd
Only in /etc/sysconfig/: dhcrelay
Only in /mnt/sda10/etc/sysconfig/networking/devices: ifcfg-eth0
Only in /mnt/sda10/etc/sysconfig/networking/profiles/default: hosts
Only in /mnt/sda10/etc/sysconfig/networking/profiles/default: ifcfg-eth0
Only in /mnt/sda10/etc/sysconfig/networking/profiles/default: network
Only in /mnt/sda10/etc/sysconfig/networking/profiles/default: resolv.conf
Only in /etc/sysconfig/: spamassassin
Pretty sure notting takes care of all initscripts related stuff.
anaconda writes /etc/sysconfig/network.
