The NFS server is just the management node (10gigE to the management switch) and RAID5 or RAID6 (depending on how old the management node is). There's not a lot of NFS load at all - we use a RAMdisk for statelite boot. Other advantages we've found are that we can: 1) keep /var/log on NFS for persistent logging across reboots for non-syslog managed logs like Slurm. 2) keep the GPFS config directory on NFS so we don't need to re-provision the node by hand on a reboot (we don't allow root logins back to the management node in our xCAT config). Here is our current litefile config for one of our clusters, the entries marked as "persistent" are the ones stored on NFS: root@merri-m:~# tabdump litefile #image,file,options,comments,disable "ALL","/etc/adjtime","tmpfs",, "ALL","/etc/securetty","tmpfs",, "ALL","/etc/lvm/","tmpfs",, "ALL","/etc/ntp.conf","tmpfs",, "ALL","/etc/rsyslog.conf","tmpfs",, "ALL","/etc/rsyslog.conf.XCATORIG","tmpfs",, "ALL","/etc/udev/","tmpfs",, "ALL","/etc/ntp.conf.predhclient","tmpfs",, "ALL","/etc/resolv.conf","tmpfs",, "ALL","/etc/yp.conf","tmpfs",, "ALL","/etc/resolv.conf.predhclient","tmpfs",, "ALL","/etc/sysconfig/","tmpfs",, "ALL","/etc/ssh/","tmpfs",, "ALL","/etc/inittab","tmpfs",, "ALL","/tmp/","tmpfs",, "ALL","/var/","tmpfs",, "ALL","/opt/xcat/","tmpfs",, "ALL","/xcatpost/","tmpfs",, "ALL","/root/.ssh/","tmpfs",, "ALL","/var/adm/","persistent",, "ALL","/var/mmfs/","persistent",, "ALL","/var/spool/abrt/","persistent",, "ALL","/var/lib/random-seed","persistent",, "ALL","/var/run/slurm/","persistent",, "ALL","/var/log/","persistent",, "ALL","/var/spool/slurm/","persistent",, "ALL","/var/crash/","persistent",, "ALL","/boot/",,, "ALL","/etc/kdump.conf",,, Best of luck!
