pfSense on HP DL320e Gen8 v2 ZFS issue

emiljan

Hello,
I just installed pfSense 2.4.5 on my new hardware over the weekend:
HP DL320e Gen8 v2:
Intel E3-1220 v3
16 GB Ram
2x Intel HP NC365T (Intel i340) 4-port network cards
Disabled on-board HP 332i 2-port network adapter
2x 120GB SSD in ZFS (Mirror) (HP Smart Array B120i running in SATA AHCI Mode

I was checking the memory usage on the host via Diagnostics > System Activity when i noticed the following: https://pastebin.com/8HrCiHka

I am not sure if these [Kernel{zio}] processes are normal for a ZFS install or something wrong. Google has not been much help.

I dont see any issues with my install, did some iPerf3 tests between devices on my network and the device barely breaks a sweat, the CPU stays under 5% and temps dont go over 35c.

The speeds are almost 1GB for wired and around 500-600 Mbps for my wireless clients.

I do have an OpenVPN server running and the following packages installed:
dhcpd DHCP Service
dpinger Gateway Monitoring Daemon
iperf iperf Network Performance Testing Daemon/Client
ntpd NTP clock sync
openvpn OpenVPN server: pfSense-OpenVPN-Server
radiusd FreeRADIUS Server
syslogd System Logger Daemon
unbound DNS Resolver

Some processes are expected. That seems excessive though!

FWIW, I see the same on my tiny ZFS test VM. I think it's just listening.
Sys Act.txt
What top command does that page run? I can also check it on my NAS which has a ZFS mirror.

FOUND -> top -baHS 999

Same on my NAS. I expect it's normal.

@provels, Im not sure if top will show you what you need, but the command "procstat -ta" will list all processes running including all processes that start with zio.

I also ran a zfs scrub and zpool status command, the array appears normal without any issues reported:
