[gpfsug-discuss] Question about subnets parameter and remote cluster mounts

[Jaime Pinto]

/etc/sysconfig/network-scripts/ifcfg-ib0

Example:
DEVICE=ib0
NM_CONTROLLED=no
BOOTPROTO=none
ONBOOT=yes
IPADDR=192.168.0.1
NETMASK=255.255.0.0

There is no need to place storage and client clusters on different subnets.
Cheers
Jaime

As an example, I have a CL1 storage cluster, and a CL2 client cluster that remotely mounts CL1 storage, and they are both connected to a private IB network 192.168.0.0. Where should I define subnets=192.168.0.0/CL1;CL2 : on CL1, CL2 or both? Some directionality seems implied in the docs, but it was not totally clear to me...
