[Lustre-discuss] Mount 2 clusters, different networks - LNET tcp1-tcp2-o2ib

[Thomas Roth]

Hm, the ethernet FS is in tcp0 - MGS says its nids are MGS-IP at tcp.
So not surprising it refuses that connection.
On the other hand,
 > options lnet networks=tcp1(eth0),tcp(eth0:0) routes="o2ib LNET-Router-IP at tcp1; tcp 
Default-Gateway-IP at tcp"

results in
 > Can't create route to tcp via Gateway-IP at tcp

Cheers,
Thomas
