Is ZFS possible on APU2C4
-
@brucexling No idea but I'm wondering why you're installing 2.4.5.
-
I am under the impression that 2.5.1 has some issues with multi-Wan, and I need that capability. I did attempt a trial install of 2.5.0 when it first appeared but I had problems with the install. I think one problem was with ZFS selection, but it was a while ago so not real sure. When 2.5.2 lands and beds down a bit I’ll probably move to that.
-
@brucexling Makes sense.

using the Tinycore serial install method. Could I please ask if anyone is successfully using ZFS on an APU2C4 and if they recall any such issues along the way?
No problems installing to ZFS here multiple times on APU2E4.
Why the 'Tinycore' method and not straight from the pfSense AMD64 USB Memstick serial console image?
-
Good call bigsy. The TinyCore method was what PCEngines suggested in the nanobsd days, and it still works with current Memstick serial console images for UFS but not ZFS unless you do what I finally did, at least that has been my experience. Etcher is a cleaner method and I see it is now preferred by PCEngines so I’ll use it from now on.
Either way the result remains that fdisk is reporting the mounted root fs mismatch issue. I have just had a chat over on the freeBSD forum and the upshot seems to be that I shouldn’t believe the warning that the obsoleted fdisk produces and rather put my trust in gpart. Looks like I need to update my practices.

I get the same in my 2.4.5 installations and they are running for years.

@brucexling I'd go with rufus. -> https://rufus.ie/
Can't see the reason why a simply "dd" frontend to write to freakin' USB sticks should take a whole electron app thingy with hundreds of MB to install just to have a fancy UI ;)Besides that - just use a memstick-serial image for APUs and use Auto (ZFS) to install. Nothing special with that, we're using that with almost any device now. Only thing with PCengines thingies was with their BIOS/CoreBIOS and early problems with booting onboard SSDs etc. and if you've tried installing ZFS on USB sticks or SD/CF cards but that's waaaay back. Can't remember seeing boxes without a halfway decent SSD installed, so nothing special to the installer necessary :)

ZFS has been my choice since it is available on pfSense. Comparing UFS with ZFS, well ZFS, like btrfs, is copy-on-write, so power surges are never a problem and ZFS requires a system with ECC memory (APU2 has this), otherwise you're still not 100% safeguarded against bit errors.

No it doesn't. It is recommended - and always nice to have - but it isn't required at all.

Not claiming to be an expert and maybe I formulated it badly, but I said; "that it is required if you want to be 100% safeguarded against bit errors".
@everyone, you could read https://hectronic.se/ecc-memory-solves-bit-errors/

I ran a number of APU2 devices on ZFS.
The memstick method was successful but slow,
so I created my own dd image (via ubuntu live disk).
and then used Etcher to create new SD Cards in order build the rest of the APU2 devices.
