No, I don't have time to deal with SuSE regarding failure, the company
I am working for is growing so fast, need to add dozens of servers
every month. After switch to XFS, I seldom get problems, even if I got
problem, I can quickly reboot nfs server because it is using XFS.

Oh, you don't put much load on it. I am using nfs server as storage
server of internet application, so they get very high IO load.

Anyway, I am not tend to start a flame war between ext3 and XFS, I
choose ext3 for our MySQL server because MySQL.com suggest me that,
they said ext3 has better performance. Sorry, this is out of topic:(
