VMWare host is 128.36.115.10 as well as 192.168.88.2. Hrm. I've never actually used at NAT interface in VMWware, but isn't the 192.168.88.2 actually on the Guest and not the Host? The host takes the packets from the guest and rewrites the source address from 192.168.88.2 to .36.115.10, yes? > VMWare does the NAT-ing for me.

You have basic IP (albeit NATted) connectivity to the MDS. What does the kernel log on the MDS show when the client is trying to mount and fails? It seems pretty clear that the NATting is confusing the MDS, but why, I'm not sure. I thought the protocol was pretty NAT friendly. b. _______________________________________________ Lustre-discuss mailing list [email protected] https://mail.clusterfs.com/mailman/listinfo/lustre-discuss
