Dear all,

We have rocks 5.4 (Maverick).

I haven't been able to find much information on adding and configuring a
NAS.

I understand that this is probably because many NAS applications are
unique.

I'm wondering about a few fundamentals though, which I can't seem to find
info on.

Here's what we've done so far:

1. insert-ethers --> NAS appliance

2. partitioned NAS with:

Disk 1

16 GB /

4 GB /var

1 GB /swap

remainder /state/partition1

Disk 2

total /export/data1

These partitions were entirely a guess based on the
information that I found online concerning NAS in rocks.

I'm not sure if /state/partition1 is required.

It seems that everything went well to this point.

As I understand it from the available online info, /export/data1 on the NAS
should be automatically exported to the frontend and compute nodes; however,
I cannot see that this is the case.

Are we suppose to manually add something to the /etc/exports file on the
frontend, NAS, and each of the compute nodes? Or are we supposed to do a
"rocks add appliance" on the frontend? Or something else?

Best regards,

Bruce

Dear Bruce,

if this is true, (you can see that running exportfs on the nas), you can add

sharedDir nas-hostname:/export/data1/&

to /etc/auto.share on the frontend and then run
rocks sync users
to propagate this file all over the cluster
