Mass Amount of Corruption in ZFS Cache in System Logs?

Featured Replies

I checked my logs by accident (I was attempting to open System Devices) and saw a sea of red and found a mass amount of corruption mostly in my urbackups. What would be causing this issue? Any assistance will be appreciated. Diagnostics zip folder has been included.

Are those files static? Could just be a plugin issue detecting false positives, seems a lot of files to me to be actual corruption.

@JorgeB, it looks like those are new writes. What plugin would cause false positives?

@trurl and @JorgeB, hmmmm. I am looking at logs from over the past couple of months and I am seeing a lot of corrupted files. I just remembered while typing this that I had an actual corrupted file back in January that shutdown the whole array. Maybe the disk itself is corrupted. Could this be the case?

That plugin has been known to find false positives in some circumstances, if there are doubts, I would recommend converting the disk to btrfs or zfs, then use the built-in filesystem scrub to confirm if new corruptions are really occurring.

My apologizes for the delayed response. I will look into doing that and make sure it has not corrupted. Many thanks for y'alls patience, time, and knowledge. I hope y'all have a good Easter.
