heffe2001 Posted September 3, 2009 Share Posted September 3, 2009 I noticed today that my parity drive has had some errors during a parity check after moving my unraid system to a new case. Before the move, it showed 0 errors, now the main page shows 59 errors, and smart statistics shows 10 Offline Uncorrectable errors. I hadn't run parity since around the 19th of last month (I know, shame on me, should have it set up to do it at least once a week), but haven't seen anything wrong just checking the main page until today. I'm going to go ahead and order a new parity drive, but I'm not sure about the existing drive. I'm attaching the smart report so you guys can see what it's showing.

You have apparently performed one smart "Short" test. That is done "Offline" and is probably when the "Offline Uncorrectable errors" occurred. They are similar to Re-allocated sectors. Unless you run more smart tests, odds are the off-line uncorrectable errors will remain as they are. See here on a short description on how to interpret the SMART report: http://www.z-a-recovery.com/man-smart.htm Your drive looks pretty healthy actually... Link to comment
heffe2001 Posted September 3, 2009 Author Share Posted September 3, 2009 My real concern is the 59 errors that Unraid shows on the main page, although I don't see anything in the smart statistics that show that many. I may clear the stats, and run a parity check again to see if more crop up. Link to comment
Joe L. Posted September 3, 2009 Share Posted September 3, 2009 My real concern is the 59 errors that Unraid shows on the main page, although I don't see anything in the smart statistics that show that many. I may clear the stats, and run a parity check again to see if more crop up. Are those "parity" errors associated with the parity drive itself on the line showing the parity drive statistics,, or does it show those at the bottom of the screen near the "Check" button? There are two different types of errors. Those at the bottom are where the parity as calculated is not identical to the data drives. A small number of errors is not uncommon if you power down the array without a clean stop first. Only way to know what happened would be if you had captured a syslog after they occurred and before you re-booted. Errors on the "parity drive" itself would be where a "read" of it failed. Since your "SMART" results don't show anything major, I'd press the "Clear Statistics" button, then press the "Check" button to re-check parity. Link to comment
heffe2001 Posted September 3, 2009 Author Share Posted September 3, 2009 It was in the error column in the drive list at the top, as far as parity went I believe it said it was correct. I've got it running a check again now, and no additional errors found (it's about halfway done at this point). Link to comment
