Hi
I think (but don't know) that this is one of the differences to their own negate devices (special arm)
I think they use other file system methods to avoid this. (Ro temp and so on....)
I also think not every power loss will END ON A damaged file system.
Here I use usv ....
Does anyone know if those apu devices have a watchdog which works with pfsense ?
Or does the original arm netgate devices have a watchdog ?
In terms of price this kind of apu devices are same price as the sg1100
If I'm understand right the sg1100 have also a 2.5gbps backplate for the 3 Ethernet devices ...
-
One of the things I personally like about the APU is that they use Intel NIC's

Personaly i agree but I think if you have original pfsense hardware I think this should also be stable
-
Such filesystem errors due to power outage seem to occur with UFS only.
Install pfSense with ZFS and you will be relaxed. That was recommended here already many times. -
@viragomann Please see the following excellent document: https://teklager.se/en/knowledge-base/pfsense-ufs-filesystem-corruption-after-power-loss/

@bouke
I agree with that. That affirms what I wrote above.ZFS seems to be very robust against power outage (incomplete write processes). I'm running pfSense on ZFS at home for almost two years and had recently multiple power outage due to a fault device a week ago with no effect to pfSense. It boots up and does its job every time when the power come back.

Did a
/root: fstyp -l /dev/gptid/091891e1-98b3-11e8-9310-000db9416710 ufsBummer, seems I did not choose ZFS during install
-
Yes, try to halt the box before powering off (unmount the filesystem) if you can.
If you are installing somewhere that cannot guaranty power stability then I suggest moving /var and /tmp to RAM drives minimising drive writes and therefore the chances of writing a critical file when power is lost.

Is there any reason why Auto (UFS) Guided Disk Setup is on top in the partitioning setup and Auto(ZFS) Guided Root-on-ZFS is way below in the pfSense Installer, as most will enter through the setup and thus choose the first?
-
That Question ist very Interesting.
-
UFS is the supported install type at this time. It's likely we will move to ZFS as the default at some point but currectly the vast majority of installs are UFS and that's what we test against.
I'm not aware of any issues with ZFS though, I have several boxes running that.Steve
-
Thanks Steve, from what I remember UFS is the default Unix file system and ZFS is open source, but that's al I know, as I have more experience with ext3/4. So as those filesystems are a bit out of my wheelhouse, is there anything to say pro or contra, apart from the "auto repairing" that ZFS seems to have, when using a 16GB SSD durable and fast Solid state drive?
-
Well not much beyond UFS is far more tested and uses less resouces. ZFS uses significantly more resources but is far better at recovering from data loss or not losing it in the first place!
I'm far from an expert there either.Steve

Hello
I just made some tests today - on APU Board with a mSata ZFS Installation works like a Charm - fine !
I also Tryed to install ZFS VErsion on a APU Board with a SD Card and here it seem that ZFS dont work - is that possible ?
The ZFS Installer report a Error - but no more ...Installation on SD witz Default UFS runs fine ...
-
Not sure I've ever tried that. What size/type of card? What was the error?

I would not recommend to use a SD card like this. My estimated guess is that the SD card will wear out very soon if you are able to format it ZFS. That said: I guess the SD card is too slow compared to an SSD. I would UFS format it and use RAM disk. On the other hand: a RAM disk isn't really feasible with 4GB RAM.
I would stick with an SSD. I normally format these UFS if there's a UPS available. I will format ZFS if there isn't any.

I installed pfSense with ZFS on an APU4C4 on a 16 GB mSATA. Works without issues.

So have I too but on two APU2C0 one with a Zheino 16GB SSD and on the other on a Transcend 32GB - no issues so far ...

Hello
Regarding ZFS on SD: There is no specific Error - the Installer Says:
ZFS setup failed x

x An installation step has been aborted. Would x

Ideally, ZFS requires a system with ECC memory, otherwise you're still not 100% safeguarded against bit errors..
I read that https://pcengines.ch/apu2.htm ECC is optional, can some comment on that?
