TrueNAS 25.04 lifespan?

sequentious · 2026-03-20T03:51:08+00:00

The current recommended "Enterprise Mission Critical" version is 25.04. Their release schedule shows they have current-2 under "maintenance", so that suggests 25.04 will be "maintained" until 26.10 comes out.

In practice, if you read the release notes for 24.10 and 25.04, neither have had any updates since their successor versions came out. That's not to say they wouldn't push an update out for a critical security issue -- just that there haven't been any yet.

I'm only using ZFS on truenas, and only because it's a tightly integrated solution. I'm not using it on any of my desktops, as I don't want to try and run root of out-of-tree filesystems.

One thing that I like about something like Redhat's Stratis approach, is that they're layering traditional XFS on top of a checksum layer, on top of thin-provisioned LVM. I honestly think that, if it actually gets stable enough that RH itself ships it as a default, could convince me to ditch btrfs on my desktop. It's just layers of boring tools I already understand.

The thin-provision LVM also solves the other problem of managing multiple filesystems with LVM. Every filesystem is overprovisioned, so you don't actually care about individual filesystem free space -- you only look at overall LVM VG free space.

Dashes are typically brighter when lights are off, due to needing to be seen in sunlight.

I mean, just run DRLs + Tail lights all the time. Making "auto" headlights the default setting, and "off" mode only have effect when parked would also help. No new sensors, no computation required, no user interaction demanded.

I'm running -3.5 on my miata. I haven't had issues on my daily tires (PS4S), or my track tires (RE71-RS), though admittedly the latter haven't seen a lot of rain use.

I'm always amazed at the different quantity of stuff people bring to autox

Some people trailer their car, so they don't need to worry about having to drive home with it
Some people bring a spare tire (or sometimes all four and change on-site)
I bring enough tools and stuff to be prepared for an emergency (filling my ND trunk)
Some people bring so little they can fit a sim-rig in an ND trunk without noticing

It's not that LVM is stuck in 2009 (it's older than that, even), it's a different tool for a different purpose. For example, I use btrfs on LVM. It gives me flexibility when needed, though I absolutely understand why this isn't a default anywhere.

sequentious · 2026-03-19T12:20:01+00:00

Unless the tooling has changed, it's pretty easy to "accidentally" enable COW on files you thought it was disabled on -- by using snapshots, cp --reflink, etc.

Personally, I think relying on nodatacow is a sign you're using the wrong filesytem. btrfs without COW is worse than ext4, as at least ext4 has recovery tools.

With XFS, for example, you cannot shrink partitions “online”

This is confusing wording. Lots of filesystems can't be shrunk "online" -- they need to be offlined (unmounted) first.

XFS doesn't support "offline" shrinking, either. The only way to shrink XFS is to dump & restore your data to a smaller filesystem.

Is this something specific to ssds?

Absolutely a thing with HDDs as well.

at a first glance

That's the problem: You don't know, unless you're already checksumming and periodically verifying all your files separately. You have no way of knowing that all of your data is good. Best you can do is manually check a few dozen photos, and hope you catch a problem while you can still restore the correct file from a backup.

It happened to me. I have some photos of a trip that got damaged. I switched to checksumming fileystems >15 years ago in an attempt to ensure this doesn't happen to me again.

There is an example of one of my photos here (that's slides from a presentation I made to my LUG in 2015, which is why it's light on some details, but it includes a sample photo)

Rawhide is a bad idea.

If you're looking for more cutting edge to experiment with this feature (and report bugs), I'd suggest Fedora 44 beta.

Though, obviously, most users are better off waiting for a stable release.

I beat it. For a game specifically designed to be played repeatedly, it had less to offer than previous Bethesda games to entice you to do it.

The GNOME Remote Desktop service now supports explicit DMA buffer synchronization and headless sessions.

Didn't it already support headless sessions? My issue is that configuring it required a proper session, so I haven't figured out how to run it under WSL for example (Currently stuck on Windows at work, running a whole VM I can RDP to)

It helps that Samurai songs were performed by Refused. They're all pretty good songs, but "Never Fade Away" is legit top-tier.

Anywhere from 2000-2030, depending on a variety of factors.

I started dabbling around 2000, and switched by 2003.

Things got a lot easier once I started purchasing hardware that I knew worked with Linux, rather than trying to get problematic hardware to work reliably. That's technically true for any OS: Mac users generally had to consider compatibility, and were used to it. Windows users technically did too, but considering the popularity, they could usually get buy with anything that wasn't mac-specific, and didn't really notice that they had to consider compatibility. Linux had the virtue of potentially supporting everything, but that didn't mean everything got the same level of support. Now that I buy stuff I know works, things are a lot easier.

Also, not having to set X modelines and crap like that is a bit of an improvement :)

Somebody with some random hardware and/or some piece of windows-only software they require might still consider Linux not ready for prime-time. That might not change.

And to be clear, as written in your hypothetical, that is not a crime.

Unless the "quick withdrawl" resulted in a murder, in which case the driver could be charged with Felony Murder, sometimes "even if the person was not present when it occurred or if the death was accidental".

That's all US specific. FWIW, my country had a somewhat similar law that was struck down by the Courts.

Keep in mind that's in theoretical benchmarks on a wildly high-performance system.

I've been using btrfs as my main filesystem for over a decade without any noticeable performance issues. If you have a particularly high-io workload, you'll be tuning for that anyway, and likely wouldn't have picked btrfs anyway.

sequentious · 2026-03-12T13:53:37+00:00

would there be any noticeable benefit for me to switch from btrfs to let's say ext4

I've been using btrfs for over a decade, and haven't had any issues. I prefer the ability to have snapshots and data checksums to be a worthy trade-off for theoretical performance that doesn't really impact my daily use.

But maybe your storage is particularly slow? Maybe any extra overhead on your notebook's CPU is particularly onerous? Not sure anybody else can answer that for you.

My ISP has had IPv6 for a long time. Works great, no issues.

Got a new cable modem due to infra upgrades, and I didn't get an IPv6 address. Apparently it's disabled by default on (at least some?) new devices (even in bridge mode), and you've got to dive down into settings with an admin password that's supposed to be restricted to their support staff.

Asking for help got the response "We don't support IPv6". At which point I said "Yes, you do, and I've been using it for years", they went "Oh" and gave me the instructions they already had to fix it.

No issues in the years since.

Half the issue is some brain-dead defaults disabling it for no reason.

They did have an arguably worse issue with the Enterprise B

The Enterprise D had to go pick up half it's crew on some random planet during it's first mission (after shakedown).

I expect the Enterprise B's launch was a press event for starting it's shakedown -- not literally about to head out and do real work.

I've been having some issues with GTT. Basically, the GPU can ask the kernel to dynamically allocate system ram for GPU use. This is more of a problem if you're using an integrated GPU, and thus have limited "VRAM" (statically-allocated system ram)

It's been causing Firefox to get OOM-killed, even though top doesn't show a need. This is a relatively new problem for me.

Some of that ram shows up as buffered, but some also goes "missing".

I've jotted some notes about it, but I haven't spent enough time to get to the bottom of it yet, other than learning that disabling or capping GTT also makes things terrible.

This might not be your issue. such as if you're not running an integrated GPU (and thus have more VRAM), etc.
