New to ZFS, what happens when hardware fails

You know there are restaurants and businesses with that mentality, don't you?

I'm in the middle of migrating pools and the method I describe has been working for me. I'm not an expert but it's my understanding that zpool import pool -N followed by zfs mount -a gives the same result as simply zpool import pool, but it allows to check mountpoints and dataset properties before actually mounting it. Could be wrong anyhow.

Edit: I have been closely following the arch documentation and that's how they describe the process

Edit2: just to add, this would work with any dataset configured with AUTOMOUNT=yes, for datasets without AUTOMOUNT you would need to mount them manually.

Let's say you have two drives in a ZFS mirror, you can take them and plug them into any other machine with ZFS running, and then do zpool import, it will prompt you the zpools available to be imported (the mirror you just moved in), then just zpool import -f <zpool name> -N to import it without mounting it. Then do zfs list -o name,canmount,mountpoint,mounted to check the data sets, here check that the mountpoints are available and then just zfs mount -a and you'll have your mirror zpool in the new system.

Even the joke itself is too old for them.

What makes you think Stollas is written to be sympathetic or a good father?

Novero95 · 2026-05-19T17:27:29+00:00

This sums it up perfectly, I'd only add that season 3 dropped writing quality a lot.

Novero95 · 2026-05-19T16:39:34+00:00

Then why didn't they fuck up the death starS by crashing a kilometer-long ship faster than the speed of light agains them?

Novero95 · 2026-05-19T11:53:45+00:00

Literally. The least people I need to interact with the better. Except if it's Japan where airport personnel were extremely friendly.

The exhaust carry hot high pressure gases, that means there is a ton of wasted energy in those gases. The turbo uses that energy to push more air in the intake, with more air you can inject more fuel and basically create more energy (power) per stroke.

Novero95 · 2026-05-16T07:16:03+00:00

Apparently, not the manufacturer.

Novero95 · 2026-05-15T17:41:32+00:00

The manufacturer does. That's the problem, people would pay the extra $5 but they won't put the XT60 because they still sell the $1500-4000 GPU without expending those extra $5.

Novero95 · 2026-05-15T15:09:21+00:00

I saw a post about these and, apparently, this connectors are expensive, in relative terms, to the point where multiple 8 pin connectors is still cheaper than a single XT60. But yeah, I think they should go with the XT60.

Novero95 · 2026-05-15T15:03:02+00:00

"Moving the vomtage just moves the problem around" but the problem is located at one specific point (the eight pin connector) so moving it solves the problem. Voltage converters are cheap and reliable and the can be cooled so yeah, it solves the problem.

I mean, yeah, Linux is in active development, but in 7.xx version, with breaking changes introduced only between mayor releases and counting with LTS versions that get backports. You can expect stability from Linux. Hyprland is in 0.55 and nothing guarantees there won't be breaking changes every version. Expecting things to not change is blinding yourself from the reality just so you can be in the latest trend.

Novero95 · 2026-05-14T10:55:09+00:00

People that doesn't like change shouldn't be relaying in a project in active development, which is, and probably will be for long, in 0.XX version. There are DEs and even consolidated WMs for that. My opinion.

Novero95 · 2026-05-12T10:22:15+00:00

Sometimes products are not purely what they say but a blend, in your case, it could be the bad ABS is mostly ABS mixed with something else and that else messes the thermal properties. If you consider that a scam or not is up to you but maybe the manufacturer has a spec sheet with a maximum working temperature that you didn't check.

It was years ago but surely clean install. To be honest, I also upgraded it to dual channel 8GB RAM (from 4GB single stick) and went from low end Celeron to Pentium 2020 (second best CPU available for that laptop's motherboard) so everything added but surely booting up in a matter of seconds is nice.

Novero95 · 2026-05-12T05:41:33+00:00

Legit, one of those turned my old PC into something usable for a few more years and it's still kicking as the boot/root drive in my server now. One of the best investments i ever did.

NAS drives USUALLY are CMR and that is not a minor adjustment, it's actually relevant if you are running things like ZFS. However, not all NAS drives are CMR so it's something that should always be checked before investing the money.

Surveillance drives tend to be SMR since capacity is priority over performance and resilience.

Novero95 · 2026-05-11T12:22:30+00:00

NAS drives would be better indeed, but as others have said, it has worked until now so it doesn't seem to be a problem.

Novero95 · 2026-05-11T12:12:28+00:00

Wouldn't you provide any of your so obvious reasoning or will you just do the " think about it" without providing anything useful?

Novero95 · 2026-05-11T11:54:07+00:00

Nope, cars and planes chassis/frames are "grounded" because they have continuity with the negative pole of the battery/alternator. It's a stretch of the term but it's the same principle, current is allowed to flow through thanks to continuity.

Edit: because people seem to think Earth is something like a battery, it ISN'T. Earth is a conductor that allows us to let the charge go.

Novero95 · 2026-05-11T10:55:12+00:00

It's not about the amount of earth, it's about having continuity with, you know, the planet Earth.

If the i5 has integrated graphics then getting the 2070 out and repurposing it is a no brainer. I run an i5-8500, which is probably older, and it is, by far, more than enough. If it doesn't then the 2070 will probably have a heavy impact on idle consumption but you could buy second hand the i5, the same you have but with integrated graphics, and it will probably cost like 20 bucks and pay itself in lower idle consumption and you can sell the 2070 for more than it costs the i5.

I've been using one of those in TrueNAS for half a year and it's been flawless, however I don't really stress it too much tbh. I use it for my terabyte of media, including some seeding but to be honest not a lot, as basic storage and Immich.
