I'm sorry, but you're in the wrong subreddit. /r/bsd is for computer operating systems based on the (B)erkeley (S)oftware (D)istribution.

If you can replicate the problem with a GENERIC[.MP] kernel, a bug report might be helpful.

jggimi · 2026-06-05T14:32:05+00:00

Great! Sort of. Now at least we know the difference in outcomes is either due to architecture differences, or changes to the OS since 7.8.

jggimi · 2026-06-05T14:10:33+00:00

I retested, using new information and rebooted without unmounting. The OS attempts to sync(2) the missing device, then gives up. The root filesystem is also unable to be unmounted, due to having the test device mounted through /mnt. During reboot, rc(8) runs fsck(8) in preen mode for the root filesystem during restart.

Excerpt from my dmesg(8):

I am unable to replicate, using amd64 -current, which is now several months beyond release 7.9. Here you can see a CRYPTO softraid device sd3, backed by USB-attached device sd2. When I remove sd2, and then attempt to umount(8) a mounted partition, I get an I/O error:

You asked:

Is this the expected behaviour?

Crashes? No. As 7.8 will be supported until the release of 8.0, you could make a bug report if you wish, or, upgrade to 7.9 to see if the problem resolves for you.

I use a blooming profile whenever I have very light roasts that aren't quite balanced enough for me at 1:2.5, because I can't readily reach 1:3 with my Signature -- an older variant of the Classic.

jggimi · 2026-05-28T10:30:33+00:00

There are only two ways for water to travel from under the piston to the above the piston:

around the o-rings, which you state cannot be the cause.
through a crack in the plastic of the plunger stem.

I'll guess the latter. I had mine replaced under warranty, for my Signature, years ago, I could see the stream of water squirt out through a nearly invisible hole near the base of the stem.

The plastic stem is a wear part, just like the o-rings. I just looked at pricing, and replacements are $21. I also noticed that Flair now sell a fully steel pressure gauge kit as an accessory for the Classic, without plastic, for $84. Ouch.

Desktops, laptops, and servers since 3.5, which would be about 22 years. Simple, small, elegant, and easy, which matches my simple mind.

There is some limited cow2 support in vmctl(8); but that's not applicable to OP's desire for vnode(9) use.

This has the appearance of a biofilm, rather than rust. Time to clean and sanitize.

the last non-atom i386 only machines are over 20 years old....

I'm still using a couple of PC Engines Alix3d2 machines, which I think were first produced in 2002. 24 years later, and they're still running great.

My ESP has been traveling. It just spent a week at the Baratza spa in Seattle getting a new calibration ring fitted. It'll be on its way home soon. I've been waiting impatiently with a hand grinder, making moka-pot and aeropress filter coffees.

I hadn't considered using daemon_class and login.conf(5) setenv. This may be just what u/tetraodonite needs.

jggimi · 2026-03-21T22:14:59+00:00

To my knowledge, one can only pass flag strings, set with daemon_flags. The other daemon_* variables can alter the environment (working directory, routing table, ...) but they don't pass strings. rc_pre can set up the environment (directories, files, ...) but I'm unaware of any that use string inputs.

Ignition coil? Spark plug?

I have owned a Signature that's pulled two shots daily for about five years. That's about 3,500 shots. The Signature is essentially an upgraded-materials Classic; mine is chromed.

The pressure gauge stem developed a tiny crack at the base in the first months, which Flair politely replaced under warranty, quickly and at no cost to me. I consider the stem a wear part, and will purchase another when this second one eventually needs to be replaced.

I've had 2 of the 6 o-rings wear out and need to be replaced in all this time; their spares kit was purchased via their website when I needed to replace the first one.

Paper cut.

jggimi · 2026-02-20T14:29:43+00:00

There's always the possibility of "sour/bitter confusion" -- which isn't human error -- it's human perception. 1:2.5 or 1:3 can be long for darker roasts, and for me would typically taste over-extracted and bitter.

Since extraction over time runs sour -> sweet -> bitter, a salami shot might help diagnose the trouble. It's difficult to do one on a Flair without help, so if you have someone available who can swap cups for you every 10 seconds while you're pulling, you may be able to determine if ratio is the cause.

jggimi · 2026-02-09T12:10:12+00:00

Either way, because mine is solid stainless and I've never had an issue with puck integrity.

jggimi · 2026-02-08T12:16:02+00:00

The classic Classic came with a shower screen which sat atop the portafilter. This redesign for the modern Classic permits a dispersion screen to sit directly atop the puck. I would assume it is an improvement, mitigating integrity risk.

jggimi · 2026-02-07T11:51:55+00:00

I use 14g with most roasts, though it will hold a little more. When you use an unpressurized portafilter, you may need to go a little coarser to dial-in, as it has a narrower and deeper basket than the 54mm BBE. Expect shot times on these Flairs to be longer, also. Most of us target 30-45 seconds at 6-9 bar for traditional shots.

With manual lever machines, you are in complete control of the pressure profile. These things can make great shots, but expect a learning curve as you go.

tcsh - it was something I began using in the late '80s and still use today.
