November 28, 201015 yr My UnRAID server has been running without any major problems for over 2 years... until today. The server must have shut down at some point and now it won't even power up. A mainboard LED keeps flashing like crazy (can't find anything in the manual) and even after disconnecting everything else and resetting the CMOS, it simply won't start. specs: Asus P5B-E PLUS Intel Celeron 430 1GB PC800 RAM 550W PSU 10 samsung drives Digitus DS-30104 PCIe Sata Controller I still have a Gigabyte P35 DS3R lying around, is there anything I should know when replacing the mainboard? My data should still be safe, right? If that doesn't work, maybe it's the PSU...
November 28, 201015 yr Your data is probably just fine. When replacing a motherboard you need to get the drives back into the correct slot in the array before you start it. The array will not start by itself until you do that so it's safe when booting up the first time. It's ok that the drives are in different physical ports. You will set them in the devices page.
November 28, 201015 yr There might be a problem: some gigabyte mainboards write a "Host Protected Area" to a disk, making it 1056 bytes smaller -> possible data loss and more... Take a look at http://lime-technology.com/wiki/index.php?title=UnRAID_Topical_Index and search for "HPA" for more detailed information. I don't know if your P35 DS3R is using/producing HPA. I suggest that you make sure it doesn't before you take it for replacement. Perhaps someone here knows?
November 28, 201015 yr Author it's no use. even with the new mainboard, the system won't start. so it has to be the PSU...
November 28, 201015 yr it's no use. even with the new mainboard, the system won't start. so it has to be the PSU... Did you use the same memory strips on both motherboards? That might be another possibility.
November 28, 201015 yr You can try starting without the RAM. It should give a very complaining beep. If it doesn't, then it's probably the PSU.
December 1, 201015 yr Author I installed a new PSU and the server is starting again. unraid is also booting fine but the onboard LAN adapter isn't working. it's definitely enabled in the bios but there is no active LED and the network switch isn't getting any connection... should I just get a new NIC instead?
