February 22, 201214 yr ok, i had to shutdown the server yesterday, power outage, ups kept it live while i loged in, stoped, and shutdown. After starting back up, it started a parity sync. Odd i thought, but meh, it had been 2-3months since i last did one, and it was already 20% though by the time i realised, so i let it go. Now i've receieved i belive 1 parity sync error and 121 parity disk errors, if i'm reading it right. Would like it if someone could check for me. If the 121 errors, are disk errors i'll pull it out and check the cable on the parity drive, well i'll replug all the cables, and run another parity?
February 22, 201214 yr The parity drive is having problems. Post a SMART report for parity. How are you shutting down?

February 23, 201214 yr The drive does not look healthy. Try to reseat the cables and then do another check. If that fails then you can enter "initconfig" to invalidate parity. Parity will be recreated when the array is started. This will write to the entire disk causing the pending sector to be resolved.

February 23, 201214 yr Author ok i'll pull it out and reset the cable, and do another smart test? or do that initconfig thing?

You should be able to just perform a correcting parity check and not mess with cables or invalidating parity. When it gets to the un-readable sector, unRAID should detect the failure and re-write that sector. A single bad sector will result in the 121 read failures you saw initially. My suggestion, before you go invalidating parity, just press the "Check" button on the web-interface and let it perform a correcting parity check.
February 27, 201214 yr Author ok been away for the last few days so havn't manage to report but.. i did the sync again.. had no syn errors but had another 125 disk errors. so the web gui is showing 250 errors atm. did another short test and report the system han't been restarted at all since the initial power failure, either, so if i needed to do a restart before doing another smart test, then yea... smartctl -a -d ata /dev/sda smartctl 5.39.1 2010-01-28 r3054 [i486-slackware-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net === START OF INFORMATION SECTION === Device Model: SAMSUNG HD204UI Serial Number: S2H7JD6B102899 Firmware Version: 1AQ10001 User Capacity: 2,000,398,934,016 bytes Device is: Not in smartctl database [for details use: -P showall] ATA Version is: 8 ATA Standard is: ATA-8-ACS revision 6 Local Time is: Mon Feb 27 12:14:30 2012 EST SMART support is: Available - device has SMART capability.

February 27, 201214 yr If the parity check finished without error then its ok. The errors will not reset until the server is rebooted. The short test completed without error and the pending sector is gone. It was rewritten successfully since there are still no reallocated sectors.
