Do I have a bad cache drive?

[ZosoPage1963]

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

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:

when you say back up anything important, are you saying on the entire array or just on my cache pool?  I have not overclocked the RAM, but the bios did incorrectly identify the speeds and I did correct the speeds at one point.

just on my cache pool?

This.

 

Also still a good idea to run memtest.
