After several hours of research on the crash, it seems that FreeBSD 8.1 won't launch more than one nfsd, no matter what is configured in rc.conf. (FreeBSD 7.x does launch multiple NFS daemons). So when I added my second mount point, the CPU load went very high for the RPC services and the second NFS mount point disconnected, brining down the running VMs. PROBLEM: only one nfsd zambia# ps waux | grep nfs root 1213 0.0 0.0 5804 1508 ?? Is 5:23PM 0:00.02 nfsd: master (nfsd) root 1214 0.0 0.0 5804 1588 ?? S 5:23PM 8:06.88 nfsd: server (nfsd) The solution described here, http://forums.freebsd.org/showthread.php?t=11873 points to compiling a kernel with these options: options NFSD options DEVICE_POLLING options HZ=1000 The NFSD seems to be what solved the problem for the forum poster, but NFSD option means that NFSv4 (experimental) is what is running and that isn't supported by the VMware NFS client, so I can't use it. I don't know what to do and I would be grateful for any suggestions. Gil Vidals / VMRacks.com [image: Reply With Quote]
