On a related issue:
we are planning to install a relatively large NAS unit (in the 100TB range).
The question is: is there a limit (and if yes, how large is it?) for the
largest file system Linux can mount?
E.g., can I NFS mount a 8TB file system under Linux? (kernel 2.4.18).
Thanks for any information you may have on that problem.
