Linux's mainstream filesystems are now behind on 64-bit support (read: 20TB+ is now a problem depending on block size). Maybe you can followup with a second article now that so much time has passed.

For sake of completeness, kindly let us know of a GPL / Free NFS Client for Windows.

What about NFSv4 and a corresponding client on Windows?

NAS needs to be OS neutral as far as clients are concerned.

i.e.,

# exportfs -av host:/path

default export options are sync,ro,root_squash,no_delay. Use -o to specify options other than default, and push those changes into the kernel.

# exportfs -rv

Reexports all directories and synchronizes /var/lib/nfs/xtab with /etc/exports

-v</strong is for, of course, \’verbose\’.

You can also remove exports, independently from /etc/exports with -u (for unexport) and change options irrespective of /etc/exports on the fly.

etc….

exportfs is much more than just a tool for updating changes to /etc/exports.

A troll by any other name…. My editor told me there would be lots of trolls and I guess I found at least three of them. he also said not to respond, but I can\’t resist this time.

The first point I want to make is that yes, NAS .ne. NFS (to borrow some ancient Fortran syntax). But then again, this is LINUX Magazine and to be quite honest, I don\’t care about Windows clients. I know people do but I don\’t. If you like, install Samba, configure it, and then shut up.

Second point, particularly for @dragbirs, iSCSI is not NAS. iSCSI is for a SAN – completely different storage model. I think you need to PROPERLY read before you write.

Third point – I did not go into details about to configure NFS for performance, or which protocol to configure (v2, v3, v4), etc. because the details are so load and configuration dependent. If you want a very in-depth history and NFS deep-dive, just ask. But don\’t whine because I didn\’t write it – the articles are long enough already.

For the other people who posted comments – thanks for the comments and the details. As I mentioned previously, this article can\’t be all encompassing so I can\’t dive into details about configurations or exportfs. So I appreciate it when people post follow-up details.

And finally… I know, I know – don\’t feed the trolls. But I did this once but I\’m out of food and out of patience but I have one last comment: If you don\’t like what I write, don\’t read it. Write your own. Very few people write about storage (most of it is vendor gibberish) so we need good writers. I will even help get you published here if you like.
