Dear folks,
We are installing a large diskless cluster using CentOS 5.1. The
hardware is pretty new - Supermicro X7DWT boards with Harpertown CPUs.
Unfortunately we have some PXE-related problems described by the
following scenario:
1) Set up DHCP, TFTP and NFS on a server, prepare PXE kernel and initrd
- fine.
2) Start up the node using PXE for the first time - fine.
3) Reboot the node - PXE boot fails for all next attempts. We see that a
server gets DHCP requests and answers them, but a node doesn't response
with DHCP ack. The typical DHCP log is:
Jan 5 09:14:34 shoffner dhcpd: DHCPDISCOVER from 00:30:48:7e:24:a6 via eth1
Jan 5 09:14:34 shoffner dhcpd: DHCPOFFER on 10.1.5.2 to
00:30:48:7e:24:a6 via eth1
Jan 5 09:14:36 shoffner dhcpd: DHCPDISCOVER from 00:30:48:7e:24:a6 via eth1
Jan 5 09:14:36 shoffner dhcpd: DHCPOFFER on 10.1.5.2 to
00:30:48:7e:24:a6 via eth1
Jan 5 09:14:40 shoffner dhcpd: DHCPDISCOVER from 00:30:48:7e:24:a6 via eth1
Jan 5 09:14:40 shoffner dhcpd: DHCPOFFER on 10.1.5.2 to
00:30:48:7e:24:a6 via eth1
Jan 5 09:14:48 shoffner dhcpd: DHCPDISCOVER from 00:30:48:7e:24:a6 via eth1
Jan 5 09:14:48 shoffner dhcpd: DHCPOFFER on 10.1.5.2 to
00:30:48:7e:24:a6 via eth1
4) Anything like DHCP server restart, node reset, node power on/off
doesn't help
5) The only thing that will enable system to boot again over PXE is to
perform "bmc reset cold" command on a node using ipmitool - yes, we have
IPMI card sharing the same Ethernet interface. After that we can boot
CentOS again.
6) When Linux is loaded, if we reboot a node using "bmc power cycle"
instead of reboot or shutdown, a node will boot for the next time
without problems
7) There are no problems with a second GbE interface (without IPMI)
8) So our guess is that Linux on a reboot leaves Ethernet device in some
state that cause brain damage for IPMI+PXE combination. We tried to play
with some e1000 driver options, we are also tried latest Intel driver -
nothing helps.
Do you have any idea what goes wrong? Any help will be much appreciated.
