@daemonix It's running 24/7 since 6 months never had a problem with it.

A little question: Have you CPU Boost activated?
https://github.com/pcengines/apu2-documentation/blob/master/docs/apu_CPU_boost.md

apu2

I recently bought a new APU2 board and installed pfsense 2.4.5 release. BIOS is coreboot version v4.11.0.6.
I had mSATA 64G drive. Installation was easy and straightforward.
This setup was runinig fine for about 1 month after which I started to get the following issues.

Disk started to show some timeouts and disconnects.
I can login to the system but cannot do anything that require disk read.

I am trying to understand if this is a hardware of software issue. Is there anything I can do to troubleshoot the issue further?
PC engines mention bootloader parameter hint.ahci.0.msi="0" but it is applicable only for bios version older than 4.6.7

You can try to boot in single mode and do a "/sbin/fsck -y / " (repeat until no error show)

On the other hand it is possible that your SSD is dying ... make a backup of your config for the case that you have to change the drive.

thanks!

You're welcome,

I would check the advice from @fireodo; "A little question: Have you CPU Boost activated?" as this makes a lot off difference.

Then I may add, always install pfSense using the ZFS filesystem not the UFS (default). For a few reasons;

TRIM is default enabled (I am using mSATA), but this can also be enabled manually on a UFS filesystem, but the most important reason I advice to use ZFS is that it can 100% safegard you against bit errors, because the APU2 has ECC memory

apu2

@fireodo @Qinn Thanks both!
Good advise for my next ssd :)

Drive actually died and no longer detected by the system. Tried reseating it a few times but no lock.
I am surprised SMART didn't detected anything.
Is there any meaning to run smartd for SSDs?

stephenw10

Yes. It will show the drive wear level as spare blocks are used for example. It can't show if the controller is about to die.

Hi guys, are you running pfSense with /var & /tmp in RAM DISKS enabled on APU2?

Hi, no RamDisk here - as stated in my signature its all on a 16GB SSD.
/var/run 4% von 3.4MiB - ufs im RAM

Qinn

@sikita The whole filesystem zfs is running on 16GB mSATA SSD with ZFS only /var/run
4% of 3.4MiB - ufs in RAM

kinch

i retested. same result.
iperf client pc(lan) -> pfsense APU2E4 -> pc2 (opt) iperf server

With 2.4.4 p3 I have 750-850Mbit for 1 connection
After the update to 2.4.5 P1 I have 400-500Mbit.
Nothing changed, only the update was installed.
For me it means, there has changed something in the performance between 2.4.4 P3 and 2.4.5 (P1). But i dont know what.

Try disabling ICMP Redirects to enable the faster tryforward routing path (under System / Advanced / System Tunables set net.inet.ip.redirect & net.inet6.ip6.redirect to 0)

Ok, thanks for a hint

Hi,

First id like to say thanks for everyone advice.

Id like to ask for a little help from you.

Im having issues with slow LAN interface compared to the WAN.

I have a 100Mbit PPPoe HFC connection. When running a speed test from the apu4c4 or directly plugged in to the HFC box, i get 98Mbit but if i run it from my PC that's behind the apu4c4 its only at 71Mbit no matter what i do.

Ive tried:

Swapping Ethernet cables
Plugging directly in to LAN Port 2 and 3
https://teklager.se/en/knowledge-base/apu2-1-gigabit-throughput-pfsense/
disabling ICMP Redirects to enable the faster tryforward routing path (under System / Advanced / System Tunables set net.inet.ip.redirect & net.inet6.ip6.redirect to 0)
Upgraded to 2.4.5-RELEASE-p1 (amd64) from 2.4.4
Upgraded the BIOS to: Version: v4.11.0.4
Factory reset with no packages enabled

All with no change to my LAN speed. I'm all out of ideas here, can anyone offer any more advice on what i can try next.

Thanks

How is your CPU utiluzation when you run your test?
Can you try and update the BIOS to 4.12.0.2 and see if this helps?

Stewart

@Stella_161 This is specific to your box, not a general issue with the devices themselves so you would get a much better response opening a general support thread for this. When you do, you'll need to give more detail, specifically what packages are installed and how you're performing the test. Try a mix of speedtest.net and fast.com and see what you get. Make sure to do them both with an ad-blocker running on your PC. I've seen many instances where advertisements can eat up a CPU on a computer and give artificially slow speed results.

I have many of these boxes that are doing up to 500Mbps so the hardware is more than capable. That being said, @sToRmInG is right in that the first place to look would be the CPU %. Something may be chewing up CPU cycles on either the APU2 or the laptop you are using. Obvious suspects could be Snort / Suricata, Squid / SquidGuard, and pfBlockerNG.

Stella_161

@Stewart @sToRmInG

Thanks Guys, Ive opened a new thread for this.

Ive tried upgrading the BIOS with no change. After the BIOS upgrade i did a factory reset, no packages have only setup PPPoe and default LAN with ad blocker enabled on PC. Still only 71Mbit~.

CPU usage is minimal when running from PC: Speedtest.net and Fast.com with the same result

@Stella_161 Just to be sure, did you halt the system and then pulled the power plug, wait for a minute and then re-plug the power, this should be done after every bios update.

If I use a USB2.0 cable to the internal header of the APU2C4, how do I route it so that I can access it externally from the official black case provided by PCEngines?

When I loaded from the USB header, I had the top of the case off. I think you'd have to modify the case if you wanted to put the top back on.

Yeah, drill through it or something. I would love to just use the USB2.0 header with external USB ports than wait for the devs to fix that long-standing USB3 issue.
