We set up a 160 node cluster with a dual processor head node with 2GB RAM. The head node also has two RAID devices attached to two SCSI cards. These have a XFS filesystem on them and are NFS exported to the cluster. The head node runs very low on memory (7-8 MB). And today I ran into a kernel bug that crashed the system. Google suggests that I should upgrade to kernel 2.6.11, but that sounds very unpleasant. I am thinking of putting the raid boxes on a different box. Will separating the file-server and the head node give me back stability on the head node? Suvendra.
