After step 6 : Setup Networking, the clients booted up via PXE boot. I then booted the clients from their hard drives. Once the clients were up, I logged into each client and manually mounted the nfs_server:/home by type "mount -a".
I then continued with step 7: Complete Cluster Setup, and amazingly it went through successfully. I then did Step 8: Test Cluster Setup. What a surprise! It passed all tests. last, I click Quit and "successfully ran OSCAR install_cluster script" popped up on the shell window.
I'll have a couple of users testing the cluster soon and will keep you informed if the users encountered any problems.
The "portmapper failure" is a cloud over this cluster setup. It means I have to manually mount the home file system from the server to the client after each client reboot. Although I did edit the /etc/rc.d/rc.local and added a line at the bottom to force the client to perform "mount -a" one more time, but it did not work.
What do you think? Any suggestions and help are appreciated.

Julia
You could try disabling the pfilter service (packet filtering/security) and make sure it's not getting in your way. This will have to be done on the server and the nodes.
Let me know-

Hi, Jeremy,
Thank you very much for your reply. I checked the server and the nfsd was running.
As I said that after the clients booted up from it's hard drive, I had to log into the clients and type "mount -a" to have the home directory nfs mounted to clients.
Do you know if there's anything else I should check? Thank you.
Julia
Check to make sure the nfs server service is running on the server... JeremyAt 04:03 PM 1/3/2003 -0800, Julia Wang wrote:I'm re-posting this problem, can someone help me? Thank you. Julia
I'm building a small Oscar 2.1 cluster on top of RedHat 7.3. After Step 6, Setup Networking, the computing nodes were successfully booted up via PXE boot. I then tried to reboot it from hard drive and the mounting NFS filesystems failed.
Starting the portmapper OK, starting the NFS service OK, the NFS mounting the /home from the sever Failed. The error messages: mount: RPC: portmapper failure, RPC: unable to receive, Mounting NFS filesystems: Failed. Once the system was up, logged on as root, "df -k" showed the local file systems. I then typed "mount -a", and "df -k" showed the server's /home mounted on /home. After the RedHat 7.3 installation on the server, I edited the /etc/hosts.allow file according to the "How to Install an OSCAR Cluster", D.5, TCP Wrappers (P38). The hosts.allow file looks like this: #allow NFS service to cluster.lnx portmap: .cluster.lnx rpc.mountd: .cluster.lnx #allow ssh logins from anywhere sshd: ALL cluster.lnx is the domain name I had for the private network of the computing nodes. Thank you in advance for any help you can provide.------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Oscar-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/oscar-users-- Julia L.
