Hi folks.

 

This morning I started seeing these errors in my logs:

 

Mar  1 16:32:39 Arthur kernel: btrfs_print_data_csum_error: 102 callbacks suppressed
Mar  1 16:32:39 Arthur kernel: BTRFS warning (device nvme0n1p1): csum failed root 5 ino 19531461 off 512389120 csum 0x8941f998 expected csum 0x7d7fa01c mirror 2

The output of `btrfs dev stats /mnt/cache` is:
 

[/dev/nvme0n1p1].write_io_errs    69890
[/dev/nvme0n1p1].read_io_errs     10037

[/dev/nvme1n1p1].flush_io_errs    0
[/dev/nvme1n1p1].corruption_errs  0
[/dev/nvme1n1p1].generation_errs  0

 

However the UI shows no errors or alerts. I have ordered a new SSD to replace the obviously failing one but I think this must be a bug that it's not detected my unraid.

Currently pools are not monitored for errors, it's my oldest feature request, for now you can use this:

Thanks @JorgeB
