October 10, 20223 yr I shut down the server to install another drive. Upon boot, server was barely responsive and cpu was pegged at 100%. The only way I could shut it down was pull the plug. I rechecked all cabling for the drives. Turned it back on and getting btrfs errors. Scrub went without error, and shown below. All data on cache device seems to be intact. Any advice would be appreciated.

October 10, 20223 yr Author Solution Meh, I can't read I guess. Verify=388 means that many errors. After running correcting scrub everything is fine now it seems.
October 11, 20223 yr Author Well it seems it isn't resolved. Or else its just from when it had errors, but keep getting notifications that cache pool has errors. I have rebooted assuming it was still seeing it in the syslog. Scrub comes back clean for real this time.

October 11, 20223 yr Community Expert If you are doing this to monitor the pool you need to reset the stats with btrfs dev stats -z /mnt/cache
