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

exportfs

exportfs(2nfs) exportfs(2nfs)

Name
exportfs - exports an NFS file system

Syntax
#include <sys/mount.h>
exportfs(name, rootuid, exflags)
char *name;
int rootuid, exflags;

Description
The system call allows the specified local file system to be mounted remotely by an NFS client. This system call is usually called from
Security on the exported file systems can be improved by setting the root mapped user ID, rootuid, and two mount structure flags, exflags
for the local file system, name.

The name argument is a pointer to a null-terminated string containing the path name of the file system being exported.

The rootuid argument is used to set the user ID that root maps to. By default, root maps to user id -2.

The exflags argument contains the flags that are to be set in the mount structure corresponding to name. The following flags are the only
possible flags accepted by
#define M_NOFH 0x1000 /* no fhandle flag */
#define M_EXRONLY 0x2000 /* export read-only */

Setting the M_NOFH flag does not allow access to the fhandle of the file system's root gnode. The M_EXRONLY flag exports a filesystem read
only.

The system call returns a value of 0 upon successful completion of a operation, and -1 upon failure.

Diagnostics
[EPERM] Not superuser.

[EIO] Not enough memory in the system to service the request.

[EFAULT] Bad address or bad length of name.

[ENOENT] The name cannot be found.
