I got my replacement RMA'd Pro 2 in this afternoon (to replace the one that was stuck at CPU=77 C) , and after a couple hours with Tech support, I have to RMA that one too as it looks like a bad HD controller. It wouldn't start up with 2 disks in the bay. Both Tony and Cody (tech support guys) have been great to work with!
Back to the Pro 2 of this topic.
Earlier I said that doing a cold boot, brought the temp cycle back to 50-55. For whatever reason, that stopped and the cycle again became 50 C, up to 70 C, then back down to 50 again, and around. So I tried the 4.2.21. Did the reboot, and odd "ticking" sounds started, and the Pro 2 wouldn't boot. Shutting down by 2 presses on the power button, unplug, then starting back up, the Pro2 would light up the blue light, fan on, shut down, light up the blue light, fan on, shut down, repeat. Unplug, wait. Repeat same.
Ok, doing a Factory Default restore now. This device has 2 X Constellation ST33000650NS. Expensive buggers. Sure hope I don't have to RMA this one too. Seems like some bad luck or something. At least I'm running in to all this before I put any data on these things. The systems are coming with 4.2.19, maybe just leave it at the factory settings? Kinda bummed
I've had the setting for the drive at Raid 1, Maybe let it go default Xraid?
Anyway, keep ya posted and keeping notes here for tech support for the next call, which I hope not.
EDIT >> in the process of doing the Factory Reset. I put the disks in one at a time before I did the reset, and there was no "ticking", it wasn't until I put both disks in that the "ticking" started back up. Fortunately, in to the Factory Reset process and no more ticking. Hopefully don't have to return the HD's...
P.S. I'm getting a good collection of power supplies going since they don't want those back with the RMA
