Thanks again for the reply. The problem with this solution in my case is it loops through all drives and adds each of them to all subnets.

I need to be able to define individual drives for specific subnets. Not all the exports will need to be presented to all subnets. I.E.:

Code:

 pcs resource create nfs-b2b-hg-media-10.1 exportfs clientspec=10.1.0.0/255.255.0.0 options=rw,sync,no_root_squash directory=/nfs/exports/media fsid=1 --group nfsgroup
pcs resource create nfs-b2b-hg-hotdrive-10.91 exportfs clientspec=10.91.0.0/255.255.0.0 options=rw,sync,no_root_squash directory=/nfs/exports/hotdrive fsid=2 --group nfsgroup
pcs resource create nfs-b2b-hg-images-10.1 exportfs clientspec=10.1.0.0/255.255.0.0 options=rw,sync,no_root_squash directory=/nfs/exports/images fsid=3 --group nfsgroup
pcs resource create nfs-b2b-hg-images-10.91 exportfs clientspec=10.91.0.0/255.255.0.0 options=rw,sync,no_root_squash directory=/nfs/exports/images fsid=3 --group nfsgroup

My use case is to add new exports (this is just one part of a larger script that also partitions drives, creates volume groups, logical volumes, etc) to the cluster for varying needs.

I'm still troubleshooting, the paired arrays look encouraging..

Thanks again,

HB
