August 27, 201015 yr Hi all, I am running unRaid v4.5.1. I have 13 drives and 1 parity. Earlier this week, Disk 6 (500G) failed. Today I replaced with a 1TB drive. I have been rebuilding for about 4 hours, when all of a sudden disk 1 started showing "ERRORS" - about 260,000 and counting. Disk 1 is now blinking green.... Any advice on what to do here? I really dont want to lost both drives... Thanks!
August 27, 201015 yr Author I am now up to 2,500,000 errors and counting. My Disk 6 "Writes" number has stopped - Should it? Both Disk 1 and Disk 6 are now blinking... all else green. Getting pretty nervous....
August 27, 201015 yr Blinking Green usually indicates drive has spun down. I would not expect that when a Drive is being rebuilt but don't know enough of the inner workings yet. You can either wait for other (more experieced advice) or what I might do in this situation would be to click the Spin Up button on the Tower Menu Main page. Just seems coincidental that the default spin down time is 4hrs and you started getting these errors after 4hrs.
August 27, 201015 yr The default spindown timer is set to one hour. It is normal for certain smaller disks to spin down during a data rebuild once they are done being read. For example, if you have a 2 TB parity drive, a few 2 TB data disks, and a few 1 TB data disks, the 1 TB disks will spin down roughly half way through the data rebuild (same goes for a parity sync or parity check). Blinking green just means that the drive is spun down, so there's nothing to worry about there. No need to press the spin up button. The second red dot is a problem, though. I'm also waiting for Joe L. or one of the more experience members to advise you, since I also don't know what to do in this situation. I would just let it keep going and wait for further advice. Edit: On a second read-though, I realized that you never said you had a second failed disk (no second red dot), just a disk with a bunch of errors. That's a much better situation. Again, don't do anything yet, just let the rebuild keep going and wait for further advice in this thread. To be proactive, you should capture a syslog and post it here.
August 27, 201015 yr Disk 1 blinking green means it has spun down, likely due to the fact that it is smaller than 1TB. Suppose disk 1 is 400GB, once the data rebuild is past the 400GB mark, then disk 1 is no longer needed and will spin down. If Disk 6 (the one you replaced) is now blinking green, that indicates to me that it has finished rebuilding. Have you refreshed the browser?
September 1, 201015 yr No expert here, but if Disk 1 is spun down, how could it's error count go from 260,000 to 2.5 million? A spun down disc shouldn't have any activity.
