siron1992 Posted October 21, 2023 Share Posted October 21, 2023 Hey All, Unraid's just flagged up that Disk 1 (which is only 2 weeks old) has a SEEK_ERROR_RATE issue with the status FAILING NOW. What does this mean? And what should I do with the Data on that disc? I have Disk 2 which is empty. DO I need to manually copy data from D1 to D2? I was under the impression that I could just remove D1 and replace with a new drive, and the data would be recovered from Parity? Logs attached. Thanks! alfred-smart-20231021-2102.zip Quote Link to comment

No, a disk rebuild to a new disk will work. An advantage of also copying data is redundancy incase something goes wrong during rebuild. 1 Quote Link to comment

Thanks for the advice - last Parity Check was 10 days ago, should I rerun the check before removing the drive? In terms of moving the data for redundancy, is it just a case of manuall moving everything from /mnt/disk1 to /mnt/disk2 or am I missing something here? Quote Link to comment
Solution dboonthego Posted October 21, 2023 Solution Share Posted October 21, 2023 1 hour ago, siron1992 said: should I rerun the check before removing the drive? I wouldn't. Just replace and rebuild the disk. If you choose to also copy, toss it in a subfolder on disk2 that way when you rebuild disk1, you won't have duplicate files in the same path across multiple disks. This will do it. rsync -avhPX /mnt/disk1/ /mnt/disk2/disk1copy/ 1 Quote Link to comment

You've answered my inital question, but just for clarity around Parity - I assume it continually writes to parity and the 'Parity Check' is just a fail safe to ensure Parity is accurate? Is that correct just so I understand how Parity works? Quote Link to comment

siron1992 Posted November 3, 2023 Author Share Posted November 3, 2023 This has become an issue again. Im now on my THIRD drive! All drives fail in Disk 1. Drive 1 - Seek Error Rate of less than 30. RMA'd and replaced with new device. Drive 2 - Seek Error Rate of less than 40. RMA's again and replaced with another new device. Drive 3 - Been in overnight and Seek Error currently at 92 and dropping, even with no data being used/pulled from the Array. I'm losing my marbles! @JorgeB I heard you run lots of Toshibas. Any thoughts? I just cant understand why its always Disk 1 thats failing and not my Parity or Disk 2. Quote Link to comment
JorgeB Posted November 3, 2023 Share Posted November 3, 2023 The Seek error rate failing now attribute seems to be a common issue with some Toshiba models, possibly a firmware problem, the error usually goes away on its own, probably not worth replacing the disk just for that. Quote Link to comment
