anthropoidape Posted February 24, 2011 Share Posted February 24, 2011 Hi, I upgraded my UnRaid server to version 4.7 yesterday. I believe I did this properly, just overwriting three files with new versions on the flash drive. The result is an inaccessible unraid server, although at least it seems to be running version 4.7! I have attached a screengrab of the problem, in short it is showing a "replacement drive" even though I made no hardware changes and haven't done so for several months. It also believes the replacement drive to be too small by 4 bytes, even though it's the same drive. It should in theory also be the same size as the other 1.5TB drive next to it, and it isn't. The thing is, even if it is a failing drive I would still like to have the server running with a virtual disk, not just failing to run altogether. Also, I did check that everything was running smoothly prior to attempting an upgrade and it all appeared to be okay. Here's the screenshot: As you can imagine it is really not good having no access at all. None of the drives were full anyway, is there anything I can do here? I will be very grateful for any help.

lionelhutz Posted February 24, 2011 Share Posted February 24, 2011 Hmm, Gigabyte motherboard? That looks like a HPA problem. Do a search, you will find tons of crap about it. Also, go to the devices page and unassign disk5 and then you can start with a simulated disk. Peter Quote Link to comment
anthropoidape Posted February 24, 2011 Author Share Posted February 24, 2011 Thank you for the quick reply Peter. The motherboard is actually an Asus K8V-X, would HPA be a potential problem there too or is it just gigabyte? Quote Link to comment
dgaschk Posted February 24, 2011 Share Posted February 24, 2011 Did you get that drive new? Was it ever in a Gigabyte MB? Quote Link to comment
anthropoidape Posted February 24, 2011 Author Share Posted February 24, 2011 Thank you both. I admit I am a bit puzzled, but to cut a long story short I reset the drive to its native maximum using Seatools, and it has now been accepted as a replacement drive by unraid, so a parity rebuild is underway. It is now showing the same size as the other identical drive. I don't really understand how the drive lost 4 more bytes on the reboot/upgrade to be honest, but I guess it doesn't matter as the drive was clearly undersized (because of HPA?) anyway. Thanks again!

anthropoidape Posted February 24, 2011 Author Share Posted February 24, 2011 I should add: yep, bought the drive new, but I am 99.99% sure it has been in a PC with a gigabyte MB at some stage, as there are a few of those floating around here. I hadn't heard of HPA before, it now officially annoys me though Quote Link to comment
lionelhutz Posted February 24, 2011 Share Posted February 24, 2011 Interesting that a "new" drive would have a HPA on it without being connected to a Gigabyte motherboard by the purchaser... Glad to hear you got it patched up and all is god again. I hadn't heard of HPA before, it now officially annoys me though LOL, yes it's annoying a lot of unRAID users. Peter Quote Link to comment
mazma Posted February 24, 2011 Share Posted February 24, 2011 I'm attempting to upgrade from 4.56 to 4.7. If downgrade the issue goes way and everything works just dandy again. I have the same issue with a GB board. I don't have access to a regular pc where I can place the drive in and run Western Digitals equivalent of SeaTools to format it to its maximum. My server is headless at the minute, so I can't reboot to check if HPA was disabled in the bios, but I do remember upgrading the bios when I built the thing (didn't know about hpa then!) What other options do I have? Quote Link to comment

mazma Posted February 24, 2011 Share Posted February 24, 2011 no longer headless... the only thing I can find in the bios is an option for dual bios which has two selectable options: backup from dual bios back from hdd hda backup from dual bios is selected Quote Link to comment

If your board does not turn off HPA by default then the problem will reoccur when CMOS is reset for any reason, e.g., the CMOS battery dies. Having the option to disable it is not good enough; the board must default to the off setting. Sometimes a BIOS update will fix the problem. Although, other have replaced there MB due to this problem. Motherboards the have HPA enabled by default are not suitable for unRAID. Quote Link to comment
mazma Posted February 24, 2011 Share Posted February 24, 2011 so your saying there is no way around it although the hpa option isn't selected in the bios? a new MB is the only solution? Quote Link to comment
lionelhutz Posted February 24, 2011 Share Posted February 24, 2011 Those appear to be recovery options to get the origional BIOS settings back. Sounds like you can't turn off the HPA use. Might be a good time to replace the motherboard or just stick with the working unRAID version. Also, you should start a new thread for your own issue... Peter Quote Link to comment
