I received a notification from Unraid saying I have errors on my cache pool but I can't identify any issues?

 

The notification shows up as:

Unraid Status
ERRORS on cache pool
warning
No description

I've tried to scrub the cache and it shows up as no errors

 

Rebooting the server makes the notification show up again.

 

See attached for diagnostics

You likely saw this and have a script running to check for errors, note that the original script generates a notification if the array ia stopped, i.e. /mnt/cache doesn't exist, see the current one, it will check that the mountpoint exists first.

 

 

 

yes @johnnie.black I think you're right. I checked and I do have that scrpit running. However when I ran it again it outputed all 0

btrfs dev stats /mnt/cache
[/dev/sdi1].write_io_errs    0
[/dev/sdi1].read_io_errs     0
[/dev/sdi1].flush_io_errs    0
[/dev/sdi1].corruption_errs  0
[/dev/sdi1].generation_errs  0
[/dev/sdh1].write_io_errs    0
[/dev/sdh1].read_io_errs     0
[/dev/sdh1].flush_io_errs    0
[/dev/sdh1].corruption_errs  0
[/dev/sdh1].generation_errs  0
 

So is this notification safe to ignore? Does that mean it will generate a notification every time the array is stopped? It didn't used to to that before.

Sorry, it's been an early morning and I can't read properly. I've updated my script to the current one. Thank you!
