April 4, 201115 yr I just upgraded from 4.5.6 to 4.7 and cannot get the system running. There is a difference in the size of several disks , parity, disks 1, 2, 6, 10, 11, from before the upgrade to now. Here is the configuration of my server. Disk status Model / Serial No. Temperature Size parity WDC_WD2001FASS-0_WD-WMAY00421411 WDC_WD2001FASS-0_WD-WMAY00421411 38°C 1,953,513,492 1,953,513,496 disk1 WDC_WD1001FALS-0_WD-WMATV2312775 WDC_WD1001FALS-00J7B1_WD-WMATV2312775 39°C 976,761,492 976,761,496 disk2 WDC_WD1001FALS-0_WD-WMATV2151825 WDC_WD1001FALS-00J7B1_WD-WMATV2151825 41°C 976,761,492 976,761,496 disk3 WDC_WD1001FALS-0_WD-WMATV2243983 41°C 976,762,552 disk4 WDC_WD1001FALS-0_WD-WMATV2244727 39°C 976,762,552 disk5 WDC_WD1001FALS-0_WD-WMATV0051418 40°C 976,762,552 disk6 WDC_WD1001FALS-0_WD-WMATV0666868 WDC_WD1001FALS-00J7B0_WD-WMATV0666868 38°C 976,761,492 976,761,496 disk7 WDC_WD1001FALS-0_WD-WMATV5945216 38°C 976,762,552 disk8 WDC_WD1001FALS-0_WD-WMATV5996312 40°C 976,762,552 disk9 WDC_WD1001FALS-0_WD-WMATV2242106 41°C 976,762,552 disk10 WDC_WD2001FASS-0_WD-WMAY00419857 WDC_WD2001FASS-0_WD-WMAY00419857 37°C 1,953,513,492 1,953,513,496 disk11 WDC_WD2001FASS-0_WD-WMAY00421179 WDC_WD2001FASS-0_WD-WMAY00421179 36°C 1,953,513,492 1,953,513,496 I remember when I added the 2T drives I had to swap the parity drive with the data drives so the one reporting the highest size was in the parity position even thought the 2 T drives are all the same model number. I did not change any of the drives or their position when I upgraded. I don’t understand why they are reporting different size now after I upgraded. Do I have to go back to 4.5.6? Any ideas? Rick I just went back to 4.5.6 and there is no longer any size error.
April 4, 201115 yr What motherboard do you have? Is HPA enabled (it shouldn't)? Search the forums on HPA and it'll provide a ton of info for you
April 4, 201115 yr Author I have a Giabyte GA-EP45-UD3P motherboard. I searched for HPA and found that other Gigabyte boards have this problem. I will try to upgrade the BIOS as one person suggested. Thanks for the help Rick
April 4, 201115 yr Yes, you'll have to fall back to 4.5.6 until you get the HPA's removed from the drives. You need the array considered valid so you can rebuild 1 drive at a time as you remove 1 HPA at a time. Peter
April 8, 201115 yr Author I think I have a big problem. I have six drives that need to have hpa removed. I used hdat2 to remove the hpa from the first, rebuilt the disk and got the message that it was successful. I started on the second drive and then noticed that only 30% of the first drive is used when it was 80% before the rebuild. Has the entire array been damaged? Have I lost everything? IS ther a way to recover from this? Help!
