Hi,
I want to configure the Lustre using Myrinet NIC running TCP/IP (ethernet emulation).My configuration steps as following:
1.Change the kernel to 2.6.9-55.0.9.EL_lustre.1.6.4.1smp which is required by the lustre-1.4.6.1  vi /boot/grub/grub.conf  reboot from the new kernel
2.install the MX  install the MX with --with-linux=<new kernel>  vi /etc/sysconfig/network-scripts/ifcfg-myri0      DEVICE=myri0     BOOTPROTO=static BROADCAST=172.19.2.255 HWADDR=00:60:DD:49:10:A6 IPADDR=172.19.2.34 NETMASK=255.255.255.0 NETWORK=172.19.2.0 ONBOOT=yes TYPE=Ethernet
3.install the lustre   rpm -ivh   lustre-ldiskfs-3.0.3-2.6.9_55.0.9.EL_lustre.1.6.4.1smp.x86_64.rpm  rpm -ivh  lustre-modules-1.6.4.1-2.6.9_55.0.9.EL_lustre.1.6.4.1smp.x86_64.rpm  rpm -ivh  lustre-1.6.4.1-2.6.9_55.0.9.EL_lustre.1.6.4.1smp.x86_64.rpm
4.Configure Lustre on MGS and MDT node.  vi /etc/hosts  change the line "127.0.0.1               snode localhost.localdomain localhost"   to   "172.19.2.34             snode localhost.localdomain localhost"  ifconfig lo down
  vi /etc/modprobe.conf add the line "options lnet    networks=tcp"
  mkfs.lustre --reformat --fsname datafs --mdt --mgs /dev/sdb1  mkdir -p /mnt/data/mdt  mount -t lustre /dev/sdb1 /mnt/data/mdt
  mkfs.lustre --reformat --fsname datafs --ost --mgsnode=snode at tcp0 /dev/sdb2  mkdir -p /mnt/data/ost0  mount -t lustre /dev/sdb2 /mnt/data/ost0
  when I executed "mount -t lustre /dev/sdb2 /mnt/data/ost0",error occured. "mount.lustre: mount /dev/sdb2 at /mnt/data/ost0 failed: Input/output error Is the MGS running?"
  Do you know what is the problem? How to configure the Lustre using Myrinet NIC running TCP/IP (ethernet emulation)?
 
  Wish your help!
  Happy new year!
