Parity Check Extremely Slow

and how can I improve the performance ? should I move my parity disks to another SATA controller ? in another PCI-E slot ?

The speeds seemed quite reasonable when there was nothing writing to the array drives so not sure that there is an easy fix for this.   I have no idea though why your VMs and/or Docker containers cannot run while a parity check is running as the critical shares for performance (appdata, system) do not seem to have files on the array.

what about those unclean shutdown ?

At the moment I have no further ideas on this I am afraid.   Maybe someone else might chime in with an idea.   Do you have the syslog server enabled so that you have a syslog that covers the whole shutdown and reboot process?

 

It does seem to be the most important issue though as if you could stop this happening so you would only get parity checks when you wanted/scheduled them they would be less painful.
