Lustre 1.6 Operations Manual

7.2 Elan to TCP Routing
Servers megan and oscar are on the Elan network with eip addresses 132.6.1.2 and
.4. Megan is also on the TCP network at 192.168.0.2 and routes between TCP and
Elan. There is also a standalone router, router1, at Elan 132.6.1.10 and TCP
192.168.0.10. Clients are on either Elan or TCP.
7.2.1 Modprobe.conf
modprobe.conf is identical on all nodes, run:
options lnet 'ip2nets="tcp0 192.168.0.*; elan0 132.6.1.*"' \
'routes="tcp [2,10]@elan0; elan 192.168.0.[2,10]@tcp0"'
7.2.2 Start servers
To start router1, run:
modprobe lnet
lctl network configure
To start megan and oscar, run:
$ mkfs.lustre --fsname spfs --mdt --mgs /dev/sda
$ mkdir -p /mnt/test/mdt
$ mount -t lustre /dev/sda /mnt/test/mdt
$ mount -t lustre mgs16@tcp0,1@elan:/testfs /mnt/testfs
