Re: [Xen-users] lustre clustre file system and xen 3

[Karsten Nielsen <karsten-xen@xxxxxxxxxx>]

Mayby I frased my question wrong. I have read a lot on the mailing list 
about pros and cons of different ways to make the file backend avalible 
to multiple physical servers.
But it seems that there are no real good answer to that question as fare 
as I have read. There are pros and cons to every solution.
What I was looking for is a file backend that performs very well and is 
relayable.
If I want to use ocfs2 I cannot resize the file system.

If I want to use GFS it's performence is not that great 
(http://guialivre.governoeletronico.gov.br/mediawiki/index.php/TesteGFSGraficoRaid10_ext3vsgfs 
  and 
http://guialivre.governoeletronico.gov.br/mediawiki/index.php/TestesGFS )
Mayby I am making this to complicated and should not worry about the 
lock system of clustre file systems what I am looking for is realy 
performance and relyability.
Any hints ?
And why do you think that Lustre is at bad idea ?
