Thank you for the reply. Actually, I believe I described the desired command output poorly. In the snippet I posted, the 'exports' array would define the resources that I'd want to define:

Code:
declare -A exports
exports[${nfsenv}-${dirs[0]}-10.1]=${cs101}
exports[${nfsenv}-${dirs[1]}-10.91]=${cs1091}
exports[${nfsenv}-${dirs[2]}-10.1]=${cs101}
exports[${nfsenv}-${dirs[2]}-10.91]=${cs1091}

So the commands I'd want to run would be:

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

Notice the need to increment the 'fsid' based upon the exported directory (media=1, hotdrive=2, images=3). If a given directory is exported to multiple subnets, it will maintain the same 'fsid'.

I will test further and welcome any suggestions.

Thanks,

HB

ocf_heartbeat_exportfs

OCF_HEARTBEAT_EXPORT(7) 					OCF resource agents					   OCF_HEARTBEAT_EXPORT(7)

NAME

       ocf_heartbeat_exportfs - Manages NFS exports

SYNOPSIS

       exportfs [start | stop | monitor | meta-data | validate-all]

DESCRIPTION

       Exportfs uses the exportfs command to add/remove nfs exports. It does NOT manage the nfs server daemon. It depends on Linux specific NFS
       implementation details, so is considered not portable to other platforms yet.

SUPPORTED PARAMETERS

       clientspec
	   The client specification allowing remote machines to mount the directory over NFS.

	   (required, string, no default)

       options
	   The options to pass to exportfs for the exported directory.

	   (optional, string, no default)

       directory
	   The directory which you wish to export using NFS.

	   (required, string, no default)

       fsid
	   The fsid option to pass to exportfs. This can be a unique positive integer, a UUID, or the special string "root" which is functionally
	   identical to numeric fsid of 0. 0 (root) identifies the export as the root of an NFSv4 pseudofilesystem -- avoid this setting unless
	   you understand its special status. This value will override any fsid provided via the options parameter.

	   (unique, required, string, no default)

       unlock_on_stop
	   Relinquish NFS locks associated with this filesystem when the resource stops. Enabling this parameter is highly recommended unless the
	   path exported by this exportfs resource is also exported by a different resource.

	   (optional, boolean, default 0)

       wait_for_leasetime_on_stop
	   When stopping (unexporting), wait out the NFSv4 lease time. Only after all leases have expired does the NFS kernel server relinquish
	   all server-side handles on the exported filesystem. If this exportfs resource manages an export that resides on a mount point designed
	   to fail over along with the NFS export itself, then enabling this parameter will ensure such failover is working properly. Note that
	   when this parameter is set, your stop timeout MUST accommodate for the wait period. This parameter is safe to disable if none of your
	   NFS clients are using NFS version 4 or later.

	   (optional, boolean, default 0)

       rmtab_backup
	   Back up those entries from the NFS rmtab that apply to the exported directory, to the specified backup file. The filename is
	   interpreted as relative to the exported directory. This backup is required if clients are connecting to the export via NFSv3 over TCP.
	   Note that a configured monitor operation is required for this functionality.

	   To disable rmtab backups, set this parameter to the special string "none".

	   (optional, string, default ".rmtab")

SUPPORTED ACTIONS

       This resource agent supports the following actions (operations):

       start
	   Starts the resource. Suggested minimum timeout: 40.

       stop
	   Stops the resource. Suggested minimum timeout: 10.

       monitor
	   Performs a detailed status check. Suggested minimum timeout: 20. Suggested interval: 10.

       meta-data
	   Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5.

       validate-all
	   Performs a validation of the resource configuration. Suggested minimum timeout: 30.

EXAMPLE

       The following is an example configuration for a exportfs resource using the crm(8) shell:

	   primitive p_exportfs ocf:heartbeat:exportfs 
	     params 
	       clientspec=string 
	       directory=string 
	       fsid=string 
	     op monitor depth="0" timeout="20" interval="10"
