Hmm- it was set up like that prior to my arrival- possibly for years- I simply moved files from machine 1 to the NAS and then added symbolic links on both machines to the directories on the NAS.
Not sure if its important, but there are 7 or 8 other machines (Windows, RedHat) on that switch with access to this NAS as well.
I've shut the second machine down for the moment so I can get to the bottom of this.
I read Jim's response again. I have to admit I didn't quite grasp it. He seems to be saying that the first machine has some kind of priority over the files on the NAS and the second machine is lower priority, and that I should mount the NAS to machine two (which I did, but you disagree with).. not sure if I'm getting that right.
We've had a regular weekly ufsdumps of both machines, saved on the NAS weekly for a long time without issue, for what its worth.
Does this change or clarify things any? I guess I'm wondering what is the purpose of a NAS if only one machine can use it.
Thanks for your help!

rlm_expr
rlm_expr(5) FreeRADIUS Module rlm_expr(5)
NAME
rlm_expr - FreeRADIUS Module
DESCRIPTION
The rlm_expr module allows the server to perform limited mathematical calculations. This module is not called directly in any section, it
is invoked through the dynamic expansion of strings.
For example, some NAS boxes send a NAS-Port attribute which is a 32-bit number composed of port, card, and interface, all in different
bytes. To see these attributes split into pieces, you can have an entry in the 'users' file like:
DEFAULT
Vendor-Interface = `%{expr: %{NAS-Port} / (256 * 256)}`,
Vendor-Card = `%{expr: (%{NAS-Port} / 256) %% 256}`,
Vendor-Port = `%{expr: %{NAS-Port} %% 256}`
where the attributes Vendor-Interface, Vendor-Card, and Vendor-Port are attributes created by either you or a vendor-supplied dictionary.
The methematical operators supported by the expression module are:
+ addition
- subtraction
/ division
%% modulo remainder
* multiplication
& boolean AND
| boolean OR
() grouping of sub-expressions
NOTE: The modulo remainder operator is '%%', and not '%'. This is due to the '%' character being used as a special character for dynamic
translation.
NOTE: These operators do NOT have precedence. The parsing of the input string, and the calculation of the answer, is done strictly left to
right. If you wish to order the expressions, you MUST group them into sub-expression, as shown in the previous example.
All of the calculations are performed as unsigned 32-bit integers.
