[Lustre-discuss] Question regarding multi-homed clients
Hi all, We''re running a few clients who have multiple IPs assigned to them which are not broadcast. These however are picked up by the Lustre client and the MDS evicts the client in question after bringing it up. A way around this is to ensure that only the primary interface is up when Lustre is bought up on the client. Is there however any way to restrict the client to only communicate via, say eth0? Thanks, -- Mustafa A. Hashmi mahashmi@gmail.com -------------- next part -------------- An HTML attachment was scrubbed...

options lnet networks="tcp0(eth0)"
...will make LNET always uses interface eth0 to construct a NID (i.e. <ip
address of eth0>@tcp0).
Cheers,
Eric

Hi all,
We''re running a few clients who have multiple IPs assigned to them
which are not broadcast. These however are picked up by
the Lustre client and the MDS evicts the client in question after bringing it
up.
A way around this is to ensure that only the primary interface is up when
Lustre is bought up on the client. Is there
however any way to restrict the client to only communicate via, say eth0?
Thanks,

add options lnet networks="tcp0(<interface name e.g. eth0 eth1>)" to your etc/modprobe.conf on client On 4/30/07, Mustafa A.
