Our present cluster serves out Clustered NFS to our primary network (172...) and regular NFS to our other network (192...) via the NSD servers. We are adding two new NSD servers and would like to start serving Clustered NFS to the 192... network also. So the question is: Can we serve Clustered NFS out to two different networks??
The present configuration is (2) X3650 M2 NSD servers and a third X3650 M2 for a quorum. We are adding (2) X3650 M3 NSD servers to the existing GPFS cluster. All 4 of the NSD servers have connections to the 172... GPFS cluster and ethernet connections to the other 192... network. Yes we run full GPFS and Clustered NFS to the 172... network. Note there is no direct connection between the 172 and the 192.

Re: Clustered NFS2012-04-13T16:57:01ZThis is the accepted answer. This is the accepted answer.Yes, you can define multiple ip addresses use for CNFS.
man page mmchnode:
--cnfs-interface=ip_address_list A comma-separated list of host names or IP addresses to be used for GPFS cluster NFS serving. The specified IP addresses can be real or virtual (aliased). These addresses must be configured to be static (not DHCP) and to not start at boot time. The GPFS daemon interface for the node cannot be a part of the list of CNFS IP addresses. If the keyword DEFAULT is specified, the CNFS IP address list is removed and the node is no longer conâassword. For additional information, refer to "Implementing a clustered NFS using GPFS on Linux" in the GPFS: Advanced Administration Guide.
