I am seeing a server halt and require a manual restart that I think
might be related to btrfs.
I attach the kernel log from it, in the hope that someone will

Hi,
I have disk that in the past had errors on it.
I have fixed up the errors.
btrfs scrub now reports no errors.
How do I reset these counters to zero?
BTRFS info (device sdc2): bdev /dev/sdc2 errs: wr 0, rd 35, flush 0,
