October 28, 20187 yr I can't believe it's happening again, so my old motherboard which i had an SSD 256G about a year ago i added a second 256G and setup a cache pool. I ran into read errors a few hours after the system was running, i repaired them and it happened again randomly. When i pulled a disk out the problem went away, when i added a new replacement SSD the problem happened again it seemed like some kind of BTRFS bug. Fast foward a year, i've installed my old gaming system motherboard into unraid, i have two NVMe drive's on my board and i know they are both fine given they were raid0 for over a year. I have these two disks as the BTRFS Cache pool and it's happening again.. same problem, i am moving everything off the cache drives will format it and go back to one BTRFS disk. But my question is will this be ever fixed? any reason why we can't have something other than BUGFS ?
