January 3, 20242 yr Hi, I just noticed I'm having btrfs errors on my cache pool. It appears to happen around the same time everyday at around 3 am. I run appdata backup plugin at 3 am. I looked in the appdata backup folder and a bunch of app folders say failed eg. ab_20230824_030002-failed.

January 3, 20242 yr Community Expert That's a lot of data corruption detected, recommend running memtest, then scrub the pool and delete/restore any corrupt files.
January 3, 20242 yr Author Will run the memtest when I can take it off line. I did the scrub and got this: UUID: 190382b9-8c9c-4896-8fe7-b16bbcddf8c4 Scrub started: Wed Jan 3 17:55:42 2024 Status: finished Duration: 0:04:53 Total to scrub: 233.30GiB Rate: 812.85MiB/s Error summary: csum=216 Corrected: 0 Uncorrectable: 216 Unverified: 0 How would I go about finding the corrupt files so that I can delete them? I assume this may be from a few unclean shutdowns.. Thank you!
