Yup when ramdisks are enabled it triggers a bunch of things at boot and shutdown. But it might be possible....

needs of zfs are burning up onboard components

I'm not trying to say people aren't having problems, I'm trying to understand "why" they are.

What needs of ZFS are causing this?

Burning up these kinds of components are related to the number of erase cycles, which circles back around to writes.
What parts of pfSense are doing a lot of writes? I can see persistent logging, maybe "check for updates", maybe atime property enabled? Updating persistant store for block lists?

The way I look at it, once the system is configured and running, it should be doing mostly read from the filesystem and running from memory.

Be good if you could set it for /tmp only.....

It would be really good if you could simply do ramdisk for /tmp only. No need to save/restore.

Some packages (https://www.netgate.com/supported-pfsense-plus-packages), logging of default block rules, IGMP block logging, logging set in packages, updates of block lists and country lists, nginx access log (dashboard widgets), and similar.

@SteveITS what files can use a linker file to direct to a usb drive? That model can use a usb drive right ?

Hmm, so enabling compression "on the fly" in case of logs can significantly reduce writes, yes?

zfs set compression=lz4 pfsense/var/log

Some log compression options can be enabled via the GUI, but I don’t think they use "on-the-fly" compression.

logging of default block rules, IGMP block logging

These two can be quite voluminous, but are easy to address:

Add a rule on Local to pass IPv4+IPv6 IGMP with IP options set. I think this should actually be a default rule in pfSense.
Disable logging of packets blocked by the default rule in Firewall Logs. There are often thousands of these every day, and the individual log entries really aren't of much value.

@JonathanLee Oh I have no idea. :)

Yes it does: https://docs.netgate.com/pfsense/en/latest/monitoring/logs/index.html#log-format

"ZFS already compresses this data"

Yep, mentioned above. In a link maybe, it's been a long thread. We actually don't pass the IGMP, since it's "supposed" to be blocked (always has been) we add a block rule that is set to not log. Otherwise IGMP is logged even if the logging for the default block rule is off.

I would not say IGMP is supposed to be blocked, and it's rather inefficient to do. Multicast flooding is not desirable, even if it's only mDNS.

Of course, if IGMP is completely disabled in your switches, it doesn't matter. But if it is disabled in your switches, you won't see the IGMP messages to begin with.

SteveITS

@dennypage rephrasing, pfSense blocks them by default.

Yea, that's why I called out that pfSense should add a default pass rule for IGMP.

Blocking packets with IP options that are to be forwarded is a good default, however IGMP isn't forwarded. Blocking IGMP by default makes little sense.

@dennypage @SteveITS I had commented on redmine 15400 but since it was closed I guess that my message went unnoticed.

I have created a new redmine 16068 for adding options to disable logging of packets with IP options.

Thanks to @andrew_cb and others for bringing awareness to this. I had no idea my 6100 has limitations due to the eMMC. I went out of my way to buy a 6100 over my own router build because I just wanted to setup my router and forget about it. As someone who is fully remote the router is the last thing I can have fail.

I saw the threads on Reddit and did a quick check. Just over 1.5 years of having my 6100, it’s already at 70% wear.

I bought 2x16GB Intel Optane Drives which you can get for less than 5 euro a piece and managed to get them installed and set up in a mirror for redundancy (the drives are so cheap, I think it’s silly not too). I also 0’d out my eMMC drive to ensure it does’t cause any conflicts.

I’m not thrilled that I had to do this, I’m thankful there were M.2 ports on the 6100 that I could use. But my biggest take-away is that installing your own SSD is not “supported” and could void your warranty is unacceptable. I think there should be a well documented SSD upgrade for any device that has an available slot, it should not void the warranty, and most definitely shouldn’t be discouraged.

As a side note, I really wish the installer was offline. I was sweating bullets attempting to configure the WAN in the Installer with PPoE and VLAN tagging (don’t get me wrong, it was easy, but if it didn’t work I’d be SOL).

@kingsleyadam I am glad you discovered the storage wear on your 6100 and installed an SSD before you experienced a sudden failure!

Your comment is exactly what this thread is about.

There have been many good suggestions in this thread on ways to reduce the wear of the onboard eMMC, but they do not address the main point of this thread:

If any usage assumptions or limitations are not clearly stated upfront or in the documentation, then it does not matter what the technical reasons are, how valid they are, or what workarounds are available!

You cannot advertise a ladder as great for construction work and then not disclose that it has a 100-pound weight limit, just like you cannot sell a manual transmission vehicle without an instrument panel and then say it is the user's fault when the engine blows up.

If Netgate sold ladders like they sell firewalls, what kind of chaos would result from people using the Netgate Ladder-4100 BASE version?

If there are limitations, recommendations, or "best practices" regarding firewalls with eMMC storage, then state them clearly on the product page and conspicuously in the documentation! That would significantly reduce or even eliminate this entire problem.

It has been nearly two months since Netgate acknowledged the issue, and there have been no changes. I do not understand why Netgate refuses to spend an hour copying and pasting an informational blurb to the store product pages.

You are wrong, there are a lot of changes in-progress, but I’m not getting I to this with you, here, right now.

I have several old Toyota trucks with manual transmissions that do not have tachometers.

A 22R requires some patience and effort to get it revving high enough to blow... not to mention the noise it makes will provide some obvious auditory clues.
Most 22RE are limited to 5800 RPM.
In both cases, I am pretty sure that Toyota has the maximum safe rev limit specified in the owner's manual.

Are 40-year-old Toyota trucks the best comparison for Netgate firewalls? Both offer legacy/carb and EFI options, but the evidence suggests that Toyota is the more reliable of the two.

Nothing I own has a 22R. Some have F or 2F engines. One has a 3F (belongs to the CEO, technically), but that one has an auto, and a tach.

You were talking about instrumentation on the dash, now you’re bailing for the owner’s manual.

Go ahead, show us all the proof in this FJ40 manual

Seems like you still don’t know what you’re talking about, and anre only here to fight.

Nice of you to chime in with vague and unverifiable claims.

Perhaps your time would have been better spent doing something to help protect your 'valued' customers from premature, catastrophic failures of your hardware, such as adding warnings and/or disclaimers to the product pages in the Netgate store?

You are right - I am here fighting to protect current and prospective Netgate customers against sudden, premature failure of Netgate firewalls that they are spending their hard-earned money on. My posts on Reddit and this forum have helped many users avoid disaster, particularly those who became aware that their Netgate firewall was terminally damaged and at risk of imminent failure. How many users have you helped avoid storage failure today, this week, this month, this year?

You seem passionate about discussing old Toyotas - unfortunately, you do not seem to share the same passion for educating and protecting Netgate customers from storage failure.

I will concede that the 1968-1971 Toyota FJ40 did not come with a tachometer and the owner's manual does not specify a maximum RPM for the engine. Your example of a 55-year-old vehicle proves that everything else posted in the nearly 200 comments on this thread is wrong. Clearly, nothing is wrong, and all the premature failures of Netgate devices must be some sort of shared mass-hallucination.

On the subject of Toyota LandCruisers, do you ever go out cruising with fellow enthusiasts Netgate's marketing director or gonzopancho from Reddit? Gonzopancho also lives in Colorado, and he is the co-owner of Netgate and head of engineering. You and gonzopancho have very similar writing styles, boy, it sure would be a surprise if you turned out to be him!

Maybe you guys can meet up sometime and discuss solutions to improve storage health monitoring and lifetime, and ways to better educate customers on the storage limitations of the BASE/eMMC versions of Netgate firewalls?
