Mount PFS as read/write to Control Station

Does any know how to mount a PFS to the Control Station for read and write.  I tried all variations of the following.  What I'm not sure of is what IP address to use to assign RW as part of the export option.  I'm getting errors:

touch: cannot touch `remed_mnt/test.txt': Read-only file system

## Mounting CIFS share from a VDM to Control Station (see Primus emc191369)

## List all DM and VMD
nas_server -list -all

## Find physical server where VDM resides
nas_server -i -v vdm01

## Find physical FS mount
server_mount server_2

## Export the FS

## Option 1:

server_export server_2 -P nfs /root_vdm_5/pfs13

## Option 2:

server_export server_2 -option rw,uncached,sync,no_root_squash -P nfs /root_vdm_5/pfs13

## Option 3:

server_export server_2 -option root=172.xxx.xxx.xxx,rw=172.xxx.xxx.xxx/255 -P nfs /root_vdm_5/pfs13

## Mount exported FS onto the CS

mount -o rw server_2:/root_vdm_5/pfs13 remed_mnt

mount server_2:/root_vdm_5/pfs13 remed_mnt

## unexport the FS
server_export server_2 -unexport -P nfs /root_vdm_5/pfs13
