I have a file server with two Raidcore 4850s with WHS 2011. I have two arrays, one for media; Raid 10, and another for critical files, family pics etc; Raid 5.
Last night I tried to watch a movie with my kids and it didn't work. I figured just a bad file, but then no other movies would work; ones that have worked in the past.
This morning I set about trying to identify the problem, but couldn't determine anything from Raidcore in WHS. I rebooted the machine and tried to see what was up in the Raidcore bios. It says in the bios my Raid 5 is critical and the discs in the array are full; I know they are not and this doesn't explain why we couldn't watch any movies.
My biggest problem now is that I can't get WHS to boot. I have tried to swap out a disc that was highlighted in red assuming it was the cause of the problem, but I can only get to a point where it asks if I want to enter Raidcore bios or proceed to boot and cannot select either option.
I can enter bios if I reboot, but cannot get past nor can I replace discs and rebuild the array.
The OS is on a separate HDD; no raid. I'd love to rebuild my array, but there is no option to do that and I no matter how I go about it I can't get past bios (either raidcore or motherboard)???
I tried to do a fresh install of WHS, but I can't even do that. Whenever I'm asked to enter bios or continue the keyboard input no longer works, but if I want to enter bios at boot it works fine; same goes for once in the bios(es).
I have also tried removing the raidcore cards and booting, but it won't load WHS. It asks if I want to repair windows, but won't let me select the last back up (I have a separate 2tb HDD for back-up).
I'm not familiar with the RAID Card in question, but does it have a removable/interchangeable cache module? Do you have any way to flush the cache on the RAID card?
I've seen a lot of finicky RAID cards that just needed power removed (unplug the server), reseat the cache module (if applicable), then restart the PC. Either that or it sounds like your RAID Controller may be dying.
Just read your second post. Could you boot with an OS disk and run a chkdsk against the server drive?
