I have recently migrated from WHS 2011 to Essentials 2012. There were no hardware changes; 2012 is running on exactly the same machine:
- Gigabyte AM3 motherboard with Phenom X4 CPU
- 2x Seagate Constellation hard drives in RAID 1 on a RocketRaid 622 controller for the O/S
- 6x various hard drives on motherboard SATA, configured as single disk volumes
- 7x Seagate 1GB SATA drives in RAID 5 on a 3ware/LSI 9500SE controller
It started out on WHS v1, was migrated to WHS 2011 and now to WSE 2012. Other than replacing some hard drives the hardware has stayed the same and I have had virtually no issues until now, after moving to WSE 2012 (fresh install).
This may well be a hardware problem, but since the problem started with WSE 2012 I am posting this to check if someone else has had similar problems.
The server is basically a file server and client backup machine, other than device drivers and CrashPlan there is no non-MS software running on it.
Now for the problem: at random intervals, sometimes once a day or overnight, or once every few days, the server will freeze and become completely unresponsive. Only way to recover is a hard reset.
When this happens, I find that one of the hard drives' activity light will be permanently lit. Not always the same drive and always just a single one. I have checked every single event log and there is nothing. All logs are normal up to the point I initiate the hard reset.
This server is also my domain controller so it's not a good thing when it acts up,
I can't pinpoint any specific activity as the cause either, but as it seems to have to do with a disk lockup that's probably an area to suspect. The disk which appears to be locked up when the hang occurs is, again, not the same one every time, and not always on the same controller either, so blaming a disk controller is probably not the solution.
Also thinking maybe there is a problem with the SATA backplane in the Supermicro case I am using.That would not be good.
I guess this could be a memory or other hardware problem, but if anyone has a suggestion what could be the problem, please pitch in.
Anyway I have an Asus Sabertooth mobo that I could use to rebuild the server. Together with some new RAM that would take care of any mobo or RAM issues as the cause of the freezing.
The LSI card does not support 3TB drives and it is also PCI so I am considering replacing it with something more modern. The new mobo has 2 more SATA ports so I could make do with 6 ports. Can I replace the LSI card with, say, an IBM 1015 and use Storage Spaces to replace the RAID5 functionality I will lose from the LSI controller?
