@vollans Sorry to keep asking questions.
- ) If I snapshot
zroot
do I need to snapshotzroot/ROOT
andzroot/ROOT/default
? Doeszroot
not include everything else?
- Let's say I did a snapshot, made a change, and successfully rolled back:
zfs rollback zroot/var@20210308 zfs rollback zroot/ROOT/default@20210308 zfs rollback zroot/ROOT@20210308 zfs rollback zroot@20210308 shutdown -r now
And now my
zfs list
looks like this (after the rollback):NAME USED AVAIL REFER MOUNTPOINT zroot 674M 12.4G 96K /zroot zroot@20210308 0 - 96K - zroot/ROOT 665M 12.4G 96K none zroot/ROOT@20210308 0 - 96K - zroot/ROOT/default 665M 12.4G 665M / zroot/ROOT/default@20210308 388K - 665M - zroot/tmp 144K 12.4G 144K /tmp zroot/var 7.02M 12.4G 6.62M /var zroot/var@20210308 400K - 6.62M -
How do I know what set of filesystems I'm running on? Is there something like an "active" marker in
zfs list
? - ) If I snapshot
-
@logan5247 this really should get its own zfs thread, it has nothing to do with the apu2
-
@vamike I agree, but quickly in summary, you're always running the one without the @ sign - that's the current live version. You can see that the size of the "backup" of zroot is nothing. The size of zroot/ROOT/default's backup is bigger. zroot doesn't include the other, effectively, "partitions".

@dem said in PC Engines apu2 experiences:
@vollans I did a quick test in a virtual machine to figure out what the commands would be. This appears to work:
On a running 2.4.5-p1 system:
zpool checkpoint zroot
Booted from the 2.5.0 installer and in the Rescue Shell:
zpool import -f -N --rewind-to-checkpoint zroot zpool export zroot poweroff
I would like to know how you booted from the 2.5.0 installer using a virtual pfsense machine and got to the Rescue Shell?
-
@qinn In VirtualBox I put the file
pfSense-CE-2.5.0-RELEASE-amd64.iso
in the virtual optical drive and booted to this screen, where I selected Rescue Shell: -
@dem Thanks for the quick reply, I understand that.
What I would like to know is how you get to the Virtual pfSense from here as the virtual pfsense machine is not running and access the checkpoint you made?Btw I am using VM workstation!
-
@qinn Sorry I wasn't clear: I put the installer image into the virtual optical drive of the same virtual pfSense instance that I checkpointed, so the installer has access to the same virtual disk and can locate the checkpointed
zroot
pool.Edited to add: My goal was to simulate booting an apu2 from the
memstick
image in order to rewind a checkpoint, but I don't have a spare apu2 to test with. If I actually ran pfSense in a virtual machine I would use virtual machine snapshots before any upgrade. -
@qinn I never would have guessed this was somehow specific to the apu2
-
-
@dem so he should start another thread so that people actually interested in apu2 experiences can find those without digging through unrelated zfs support questions
-
@vamike I agreed it wasn't relevant here 2 days ago, and stopped responding.

Why pfsense 2.5 shows "AES-NI CPU Crypto: No" when in 2.4.x there was YES on APU2? Also on 2.5 there is in other line: Hardware crypto AES-CBC,AES-CCM,AES-GCM,AES-ICM,AES-XTS
-

Anything to do with this problem? If so, it appears to be fixed in 2.5.1.
-
@bigsy Ok, thank you. Seems to be GUI bug and does not involve using HW crypto.
-
@sikita I am on pfSense 2.5.0 and here it says:
Do you have AES-NI enabled?
-
Can anyone share there System / Advanced / Networking on a APU2
Mine are
as these are the defaults, grabbed them from a VM installation, which is not quit the same setup.
The old and not anymore recommend settings from https://teklager.se/en/knowledge-base/apu2-1-gigabit-throughput-pfsense/ are quit different!
...and there is a new settings present in 2.5.0. " hn ALTQ support"
Could anyone elaborate on all these or there settings?
-
There are no hn NICs on any APU so it makes no difference. You can disable it.

I performed all the bootloader and other tweaks mentioned in various threads throughout the years on my <= 2.45-p1 installation and now I don't remember what they all are. It would be great if somebody could post what things to look for (to remove?) when you update your apu2 from 2.4.5 --> 2.5.0.
At the moment because of the performance issues, I'm not upgrading.

Hi,
With that, I would wait a little longer
here,....you will find a lot of useful info if you even decide to upgrade...

Smooth update to pfSense 2.5.1 CE
-
Updated to bios coreboot v4.13.05.
-
@qinn Fine !
I am still on 2.4.5_1.
Did you notice any performance degradation ? -
@flok No, so far not.

I received an email notification about v4.14.0.2 and this IMPORTANT message was included:
To update the firmware and keep the runtime configuration unchanged please use the following command:
flashrom -p internal -w apuX_v4.14.0.2.rom --fmap -i COREBOOT
The persistent runtime configuration works only when migrating from versions v4.14.0.1 and later. The feature is not yet supported on apu1. Flashrom version needs to be v1.1 or newer.I did the upgrade from v4.14.0.1 with that new command without any issues. However, for the longest time this is what I've been using:
flashrom -p internal -w apuX_v4.14.0.2.rom
What is the difference?
-
@kevindd992002
I'm not by any means an expert on coreboot, butflashrom -p internal -w apuX_v4.14.0.2.rom
will overwrite the entire flash chip with the new rom file.
flashrom -p internal -w apuX_v4.14.0.2.rom --fmap -i COREBOOT
The flash chip has various partitions defined in a 'flashmap' format and this command specifies which area to overwrite. This probably allows for user altered settings such as seabios boot order changes to persist and not get overwritten during the coreboot update, but I haven't tried it out.

That's what I thought. However, with the 1st command I have never seen any seabios setting get changed when I use it to update my APU2. I'm wondering if it's really better to use the 2nd command from this point moving forward.
-
@kevindd992002 If you look at the changes to the pcEngines fork of SeaBIOS, the addition of 'support for persistent bootorder in FMAP region' has only been in the most recent release of SeaBIOS v1.14.0.1 and similarly for sortbootorder v4.6.21.
-
@bigsy I see. So we're just preserving boot order here? Since I just have one boot device in my APU2, then it wouldn't matter to me.
-
For the APU2C4, why is it that when I have a serial cable connected between its serial port and a computer, its USB ports don't work? I have a UPS plugged in to one of its USB ports and I use the NUT package in pfsense. As soon as I connect to the hardware through the serial port (using putty), the USB port does not work. Unplugging the serial cable fixes the issue and that's why I know it's the one causing it. This is happening for both of my APU2C4 boxes.

Hmmmm, I haven't seen it yet, it is true we don't even connect to MOBO in this multiple way...
Have you tried to remove NUT? (of course temporarily)

I haven't yet but I see the usb disconnect message in the terminal itself so I figured it's a board issue. I also use the USB port only for NUT so removing it will be a moot point but I can still try for the sake of troubleshooting.
-

Sure
Would it be worth doing to rule out the SW/Code issue (on NUT) in the background...
The NUT is a strange animal anyway and sometimes difficult to get to work..
It also handles USB and RS232 stuff, so I guess that's where the rub is

I already uninstalled NUT and I soon as I connected to the serial port, I still see the issue:
ugen0.2: <Unknown > at usbus0 (disconnected)
So this is definitely an APU2C4 issue. Can anyone try this?

I dont have a APU2C4 (Only APU2C0) but I would suggest to try an older BIOS version.

I'm at v4.14.0.2 but this is not the first time I've tried this. I've tried this a year ago when it was still using an older BIOS version and it's the same issue.

You say, this is the case on several boxes (MOBO)
(so no HW issue I think, some PCB schematics or BIOS)Worth a question for him:

I can't check it either, because we only use apu24d4 -

@kevindd992002 using the serial port is pretty normal, and what you're describing is not at all common. I'd probably first make sure of the power supply (marginal power supplies cause all sorts of issues), then look at whether the serial cable is dodgy/shorted/etc.

Hi,
we are not talking about just one unit, so this is not relevant advice now...

I know it's happening for two units and I'm using a power supply that I sourced from pcengines themselves. The only variable that I haven't eliminated is the serial cable that I'm using. I guess I can buy one of the good ones and try.
