I want to natively mount a Drobo5N NFS share on my FreeNAS (FreeNAS-9.2.1.7-RELEASE-x64 fdbe9a0)

Currently I have to use an iMac to play intermediate mount point for both Drobo and FreeNAS device -- this is a very slow process for mounting and doing bulk copies. The issue seems to be with the FreeNAS for mounting:

[root@freenas /mnt/ZFS-Raid-Z3/]# showmount -e 192.168.1.5
RPC: Port mapper failure
showmount: can't do exports rpc
[root@freenas /mnt/ZFS-Raid-Z3/]#

Drobo uses its own proprietary method of storing data which is inconsistent with FreeNAS.  Are you trying to cluster DROBO with FreeNAS?

No, I am looking to reformat the FreeNAS ZFS partition(s). First step is to backup the data. Hence the Drobo via NFS.
I do have ssh access to the Drobo and all items there seem to be just fine. The issue still seems to be on the FreeNAS.

Drobo is using a flavor of Linux and FreeNAS is OpenSolaris if I understand its parentage correctly. THAT could be inconsistency. :)

# uname -a
Linux Drobo5N 3.2.27 #1 SMP Tue Dec 10 22:48:37 PST 2013 armv7l GNU/Linux

From what I can find, OSX seems to be good at connecting to the drobo while other OSs are sometimes having issues, so it's not freenas specifically.

which app on the drobo are you useing to share nfs, unfsd?

if you can connect to the freenas without a problem and same with drobo why don't you just do a rsync between the two?

going to the mounting the share on an OS X device and forcing the double network traffic to write the data.
