Hello - I run a parity check monthly, but this last one was taking a very long time to finish. When I checked, it had been running for a little over 23 hrs and had over 500K errors. I've since tried it a few more times and each one starts off with good speed, then drops way down. All the the drives are not reporting any trouble and I've even tried stopping Docker thinking that may have something to do with it since I recently set it up. I recently moved to new hardware (second time in 8 years), and nothing stood out - no errors, etc. I did add a 10 GB network card, and the driver is throwing errors about the SPF module not being supported. I asked our Linux administrator about it and his guess was that it wasn't configured to support generic modules, but that should not affect a parity check.
I appreciate any insight, and have attached a diagnostic log.
Thanks
Ken
