Hi there. I upgraded today to 7.3, and upon reboot it showed 2 Read Errors on SSD cache Device 2.

Diagnostics attached, and a SMART report of that drive. I guess I'm just looking for opinions on how serious this is? Thanks for any help or recommendations.

Solved.

Post the output from

btrfs dev stats /mnt/cache

Thanks Jorge, here is the output:

Couple of read errors, likely old; click on the first pool device and then RESET stats, after that keep monitoring; if more errors show, you post the diags before rebooting.

Great, thanks for the help!

I got the same thing this morning after upgrading. I will reset the status as recommended and monitor

You should also scrub the pool to confirm there are no uncorrectable errors.
