May 2, 201214 yr Last month I had problems with my little server and finally with everyone's help got it fixed. Now my big server has shown errors after over a year of faithful service. I think these are purely disk errors but I would really appreciate it if someone could take a look to confirm this. Either way, what is the next step? Does the disk need replacing? syslog-2012-05-02.txt
May 2, 201214 yr it does look like disk3 is gone. Run a smart check on the drive, that should tell you if its ok or not. If you have unmenu installed it should have a section for you to test smart
May 2, 201214 yr Author I started a long smart test. I'll post the results. I have spare disks so if it needs replacing that isn't the problem. I just don't want to risk any data loss.

May 2, 201214 yr Even though none of the counters look bad, the message: # 1 Extended offline Completed: read failure 90% 12065 563759221 is probably bad news - I've had a couple of drives that were like this and when I took them out of the unRAID array and tested them with the Western Digital diagnostic program they failed some tests.

May 2, 201214 yr Author Thanks for the input. I will replace it tonight. I can't remember if I have already precleared the disk or not. Is there an easy way to tell if I have already precleared it?
May 4, 201214 yr Author OK, this makes no sense. I rebooted the server and ran another check and now there are no disk errors. Should I still replace the disk?
May 4, 201214 yr OK, this makes no sense. I rebooted the server and ran another check and now there are no disk errors. Should I still replace the disk? What sort of check? A parity check? Smart Test? If possible, run Seatools/WD Diags on the drive aswell?

May 4, 201214 yr Author So replace it with a fresh one and then pre-clear the old one again?? Would that take care of it?
May 4, 201214 yr So replace it with a fresh one and then pre-clear the old one again?? Would that take care of it? No... need to go to all that trouble. Stop the array un-assign that drive Start the array with it un-assigned (check the I'm sure box if needed) Stop the array once more Re-assign the drive to its same slot Start the array with it newly assigned back where it was. (again, check the I'm sure box if needed to enable the Start button) Let unRAId re-construct the drive onto itself. When it is done, you'll be back to normal.
