High loadavg, low CPU & iowait
I've got 4 servers, 2 of which are running Veritas Cluster Server (NFS only). The hardware on all 4 servers is identical. All 4 machines mount the NFS share exported by the active VCS node. The 2 machines running VCS (and VxVM) have LAs of 11+ (across 4 CPUs), whereas the other 2 have LAs of < 0.5. I can understand the active node having a high LA, but the inactive node should look more like the other 2 machines. The CPU utilization, swap utilization and iowait are almost 0.
