Pick: GFS or GNBD or NFS To make a single FS

Roboam León López · 10-21-2007, 12:41 PM

Hello everyone, I have a simple question and I hope someone can help me. I’m working in a lab with 25 desktops and my boss told me that he want to set a common file system to all desktops using only 2 or 3 desktops (so we can use several small hard drives). I’m reading about GFS and I’m not quite sure if it is the solution or if I can use only GNBD to do that. We don’t need quotas. Should I use GFS?. Someone told me I could use NFS, What would you do?

You could try using pNFS (http://www.pnfs.com/), but GFS is pretty much the standard at the moment.

As far as I understand it it could help you to have a look at http://www.open-sharedroot.org . It'll help you build up "diskless" clusters of servers/desktop on GFS/NFS basis.

Have fun.

Thanks Zyglow and elcody02 you have been very helpful I"ll give a try to GFS and if I can't do it I'll try pNFS or other solution, the page http://www.open-sharedroot.org looks very promessing.

I've another question, can I concatenate 2 GFS in 2 diferent computers to make a sigle one?

I had another idea (a picture is worth a thosand words):

Code:

<a href=http://www.freeimagehosting.net/><img src=http://img3.freeimagehosting.net/uploads/ec51b81083.jpg border=0 alt="Free Image Hosting"></a>

Is this doable?? or is it worth it?

Again ->> Picture here<<-

Yes like in your picture with GNBD that should be possible. Keep in mind that by concatenating or striping more blockdevices you decrease the availability of the storage.
