No dark mode, no use.

Backblaze of course, but we aren’t talking about the probability of seeing a failure, but of one of your disks failing, and more importantly, data loss. A binomial probability distribution is a simplified way to see the scenario.

Let’s pretend all disks have a failure rate of 2% in year one.

If you have 2 disks, your probability of each disk failing is 2%. The first disk in that array is 2%, and the second is 2%. If 2 disks fail in Z1, you lose data. This isn’t a 1% (half) chance, because the failure rate of one disk does not impact the other, however the risk is less than 2%.

So we use a binomial probability distribution to get more accurate, which would be .02 prob in year one with 2 trials, and 2 failures making a cumulative probability of .0004 for data loss.

If you have 6 disks, your probability of each disk failing is also 2%. The first disk in that array is 2%, the second is 2%, so on and so forth. With 6 disk Z2, three must fail to lose data, reducing your risk further (not to .08%, but lower than Z1).

So with a binomial probability distribution, this would be .02 prob with 6 trials, and 3 failures making a cumulative probability of .00015 for data loss.

Thats a significantly smaller risk. The other interesting part is the difference in probability of one disk failing in a 6 disk array than a 2 disk array is not 3x, but is actually barely any difference at all, because the 2% failure rate is independent. And this doesn’t even take into account large disks have a greater failure rate to start.

I’m not saying mirroring two larger disks is a bad idea, just that there are tradeoffs and the risk is much greater.

Hate to be that guy, but those maths aren’t mathing.

Less drives does not equal less chance of multiple failures. The statistical failure rate of one drive has no impact on another. In fact, analysis of Backblaze’s data showed that larger drives were more prone to failure (platter density vs platter count).

As someone who runs 3 large arrays with 8TB, 16TB, and 21TB drives respectively, know that:

• RAIDZ1 will cause tons of fear when a disk fails if you’re used to Z2. Don’t change.
• When a disk goes, the larger the disk, the slower the rebuild time, and the more taxing it is on the other disks. With Z1, if another fails during the rebiluild, you’re SOL.

Less disks is simpler, but more disks is safer. 6 disks is the perfect sized array IMO. If you don’t need more space, I’d buy a 2TB hot spare and call it a day. But if space is a concern, Z2 with 4 disks.

Edit: Those three arrays mirror each other in different locations, and the fear was still there when the Z1 had an issue. Mostly due to the headache, but still.

Does Caddy have an OWASP plugin like nginx?

Kettle?

Many 501c3 orgs only bring income in through donations.

This logic would mean all nonprofits would fail. It’s flawed.

Meta does a lot more than manage a Mastodon server. A single full-timer is likely all that is needed. Two to reduce burnout. Those costs are still high, but you shouldn’t discredit the notion that eight full timers is an exaggeration. The top comments on the toot you link are the volunteers saying exactly that.

/storage for me.

Hrm, I don’t. Part of the fun is learning how things work, and I’ve heard to many complaints of incompatibilities and lack of updates with Yuno, though I haven’t tried it, so second hand.

It’s so easy to self host! Just watch 14 hours of a talking head!

Fan of FUTO, but can’t recommend this to most people thinking of starting. Needs to be less “scary”.

Yup. I use one of those micro PCs with 4 network ports as a router, and that’s it.

The ultimate social media scheduling tool, with a bunch of AI

Mmhmm

First link at least is wildly over-claiming the difference. The data they describe is all cached in the browser and occurs once. PieFed uses ActivityPub, so network differences are moot since the same data transfers.

Do you know if there is an extension that creates a more Feedly/Flipboard like view?

Are you the person in the linked issue that I’m already responding to there? 😉

How is a piece of software like this so bad at mobile? I’ve been debating on using an archiver instead of bookmarks, but will probably try something else.

Do you ever use this with mobile?
