FileSystem XFS vs RiserFS vs ext3

Post by Alex Lau 劉俊 » Tue, 18 Mar 2003 07:00:11



Hi all I get basic understanding of the functions and different between
XFS, RiserFS and ext3. But in high volumn read write enviornment (database,
NFS email server etc), which will provide better preformance?
Thanks
Alex

NFS is a bit tricky. Reiser used to be broken on it, and at least from large
XFS NFS Servers I know that they tend to be unstable, still.

For the Database Servers, I am not sure how well they operate with
journaling filesystems. I think Linux Journal had an article on performance
on that.

Reiser might be your bet, depending on the usage pattern of the filename
space, with Ext3 catching up. Personally I love the XFS features for
resizing in connection with LVMs, but i guess you can have that with Ext3
and Reiser, too.

Greetings
Bernd

The last big problems with NFS on big ReiserFS shares where fixed with
2.4.19 (IIRC). Since then, at least I haven't experienced any logic
induced failures in this area with my heavily used diskless setups on
up to 80 GB ReiserFS, shared with NFS. I enjoy this configuration a lot.

Bye,
Pete

I've never had problems with XFS+NFS on any of my servers... Is there a
link or something you can provide?

Thanks.

Thanks for all the input. Here is some info after I get from my setting.
