Peakey Posted October 21, 2011 Share Posted October 21, 2011 I had a power cut today, when I arrived home the wife said the there was a problem, I tried to access the tower via web interface but couldn't, I then used putty to reboot which usually works fine however I now have "Buffer I/O error on device md3" and do not know how to proceed, any help is much appreciated. I have attached the syslog. Thanks. syslog.txt Quote Link to comment

Peakey Posted October 21, 2011 Author Share Posted October 21, 2011 Thanks but the tower will not start to enable me to do these checks, the tower will not boot and 2 keyboard lights are flashing on and off. Is there anyway of bypassing the error and then running reiserfsck. Would disconnecting disk 3 allow the system to boot up? Regards. Quote Link to comment
Peakey Posted October 22, 2011 Author Share Posted October 22, 2011 I have tried disconnecting disk3 this has made no difference, I get the following on the display VFS cannot open root device on null or unknown block please append a correct root kernal panic - not syncing Quote Link to comment
dgaschk Posted October 22, 2011 Share Posted October 22, 2011 Run check disk on the flash drive in a PC. Quote Link to comment
Peakey Posted October 22, 2011 Author Share Posted October 22, 2011 Thanks dgaschk, Check disk found no errors?, is there anything else I can do? Regards Quote Link to comment
Joe L. Posted October 22, 2011 Share Posted October 22, 2011 Run a memory test. Preferably overnight Quote Link to comment
Peakey Posted October 23, 2011 Author Share Posted October 23, 2011 Joe, run the memory test for 18 hours and there are no errors. and it still will not boot. Regards Quote Link to comment
dgaschk Posted October 23, 2011 Share Posted October 23, 2011 Try to boot with a different flash using the free version. Quote Link to comment
Peakey Posted October 23, 2011 Author Share Posted October 23, 2011 Yes that worked, am I ok assigning the correct parity, disk 1 and 2 for now?, I guess the problem now is knowing which file to replace on the old usb stick or do I transfer the reg code over this stick? Thanks alot. Quote Link to comment
dgaschk Posted October 24, 2011 Share Posted October 24, 2011 Reformat and install unRAID the original Flash drive. Your key will only work on the original flash drive. Quote Link to comment
Peakey Posted October 24, 2011 Author Share Posted October 24, 2011 Thanks dgaschk & Joe L it is working again now, Thanks for taking the time to help me, I appreciate it. Regards Gary. Quote Link to comment
elmetal Posted July 29, 2012 Share Posted July 29, 2012 so a format (on windows) and reinstall was all you did to fix it? I am running a brand new mobo/cpu/memory combo, memtest works fine, yet I get that error very randomly... I've tried different combinations and once I DO get it to boot, it only boots once, the second time doesn't boot.... very weird, I'm HOPING it's not the motherboard Quote Link to comment
