High IO Pressure Stall
I have been noticing High IO Pressure stall on all VMs, interestingly not on LXCs. What could be the reason? I can't figure out. For the context, I am using 2 x 2TB NVMe in ZFS mirror and other 2 20TB HDD's as another ZFS pool.
Interestingly it seems all started after 15th May. Any idea how to diagnose the issue. I don't notice any slowness in the system (running self hosted apps and a pfsense VM), it just the graph makes me worried. SMART shows no issues, neither ZFS pool heath.
I tried to shutdown all VMs except the pfsense firewall, and it still showed a high IO pressure stall
