Been running fine for a few months now. Today, the speed (8x600GB Velociraptors) on a PE 2950 slowed to a crawl. Not DOA, just VERY slow over 10GB NICS.
Just tried to web in and I cannot get to the web interface. Stopped and started apache.
Seems as though I make it 6 months and then something goes kaflooey on DSS.
Any ideas before I migrate everything back over to FreeNAS so I can reboot?
Your issue of re-activation being triggered, could be a sign of failing boot media.
Yes, USB is supported, but most USB media is only good for a few years and starts to flake out, showing the behavior you describe.
