Hi Michael,
Yes, the head node is booted completely before the compute nodes. I have also tried to reboot one compute node when the rest of the cluster is running. So the /home in the head node was already using by the other compute nodes. However, the rebooted computer node still could not mount the /home and /nfstmp, except if I manually executed "mount -a".
Thanks!
Thanks!
Andy

the problem sounds like. If it was a problem with the fstab "cexec
mount -a" wouldn't work...
