January 29, 20206 yr Started getting these last night, and the warning that unraid cannot write to cache. I currently have 2 small SSD drives in a cache pool. Appdata and VM's are backed up, but just wondering is this a bad cache drive or something else? SDE is Samsung_SSD_860_EVO_250GB, SDD is a 240GB SSD Jan 29 07:34:04 Tower kernel: BTRFS critical (device sde1): corrupt node: root=7 block=243408191488 slot=37, bad key order, current (18446744073709551606 128 473199058944) next (18374686479671623670 128 473213054976)
January 29, 20206 yr Community Expert Pool is full of checksum errors, you need to backup anything important and reformat, there are some recovery options here if needed. So many errors suggest a hardware problem, btrfs doesn't do well with RAM issues, it would be a good idea to run memtest, also make sure RAM isn't overclocked, respect max speed depending on config:

I have not overclocked the RAM, but the bios did incorrectly identify the speeds and I did correct the speeds at one point.
