Thanks for you reply, Andy. Because the nfs server setting is configured long time ago and it works other 8 computers with SL 4.6, I think it is not a problem.
Thanks for your advice, but our lab server can be accessed only in the lab. So, there's no security problem. I found something. With the setting I wrote previously, the one written latter ( /home ) will be mounted. In this situation, if I type mount -a, /data is also mounted. I think this means that fstab file syntax and nfs server setting is all right. Am I right? Additionally, NFS server is SL 4.6 and clients that drive me crazy are SL 5.4 and SL 5.3. I want to install SL 4.6, but its kernel doesn't recognize i7 860.
