During the "make installWorld" part of RCG3.0.2 install the /opt/rtcds NFS server crashed (h1fs0). We reset h1fs0, but the NFS services did not come back cleanly. We restarted the nfs-server daemon and the services restarted correctly and the NFS clients reconnected.
Looking at the h1fs0 logs, problems were being reported starting at 09:05 PDT this morning.
We are restarting the install process and monitoring the error logs and disk usage carefully.
