May 24, 20233 yr Very similar situation to this post: Version: 6.11.5 btrfs cache drives: 4: 2x Samsung 970 Evo Plus nvme 1x Samsung 850 Evo sata 1x Crucial mx500 sata 1. The dashboard's log was reporting 100% full 2. I restarted unraid based on a forum recommendation. Dashboard log was back to normal Crucial drive is reported missing 3. I shut down Unraid, checked connections and started again and Crucial drive is back in cache pool as normal 4. Docker containers won't start, VM wont start either. System log shows "read error corrected" and "parent transid verify failed" 5. I've tried a scrub but it aborts immediately. When run in Cli the error reads "ERROR: scrubbing /mnt/cache failed for device id 1: ret=-1, errno=30 (Read-only file system)" I'm not sure how to proceed. I don't have any current backups and my array is a USB drive as my setup is SSD only and my understanding was SSDs in the array was ill-advised. Diagnostics attached. tower-diagnostics-20230524-0923.zip Edited May 24, 20233 yr by ronmcmxci
May 24, 20233 yr Author Update: I must have enabled repair mode under filesystem check. I re-entered maintenance mode to run another file system check and disabled repair mode. File system check was good. I was then able to restart in normal mode and the scrub is now running. Edited May 24, 20233 yr by ronmcmxci
May 24, 20233 yr Community Expert Make sure there are no uncorrectable errors when the scrub finishes.
May 24, 20233 yr Author Looks okay I think? Error summary: verify=12891 csum=11905024 Corrected: 0 Uncorrectable: 0 Unverified: 0 Should I rerun the scrub with the repair corrupted blocks checked?
