Unraid 7.3.0 - BTRFS critical Error on Cache drive

Featured Replies

I'm getting errors on my single cache drive. Started seeing issues when the cache went into read only mode. Looked at the diagnostics and saw the BTFRS Errors. I've tried a scrub and there were no errors. I've also tried backing up the data and reformatting the drive only for the errors to come up after 5 days. Is this a hardware issue? Do I need to replace the disk or ram? Thanks.

Btrfs is detecting data corruption; the first recommendation is to run memtest.

Looks like it is a memory issue. Put off on running the memtest till now because I had to move the server to get a display. Thanks for your help!
