Yeah isn't btrfs a really old filesystem that no one really uses anymore or am I thinking of something else?
It's the most up to date and modern filesystem with any widespread use. Literally every filesystem you know is much older except for maybe ReFS.

BTRFS has been around for a long time, yes
In total years, yes. Compared to any other filesystem, no. I think you guys are thinking of Reiser.

Will have to do some reading to see what's changed in last few years. I admit I have not kept up with it.
BtrFS has been the "future" filesystem for Linux for years. But it's not been far enough along for most places to put into production yet. It's just getting to that point, now. That's why it is going to desktops, but not servers, at this point. This is the stage prior to it starting to replace XFS and EXT4 in production servers.

As you said, Fedora users are just beta testers for real production use. Consider it production ready when it ends up in RHEL.I read this a couple of weeks ago. Has some more info: https://lwn.net/Articles/824855/

We had it in production here on several systems. We suffered no end of FS corruption, and snapshots that won't delete for various reasons...systems randomly hanging and going down... We've upgraded all of the systems to newer OSes and use EXT4.

Why EXT4 and not XFS? XFS is the mature, stable, fast one.
Why were you using BtrFS in production? It's not considered ready even now, let alone anytime in the past. It's hoped to be classified as production in 1-2 years.

No, that's when it's old. When it is in Fedora Server is when it's production.

For the same reason that Fedora is trying to push it now... The vendor (SuSE, for us) thought it was a good idea to push as a sensible default at the time.

Fedora isn't pushing now, that's for desktops. Where those things don't really matter. And BtrFS has been pretty stable for a while now. No idea what Suse was up to, but blindly taking defaults is never a good idea. That's how people got RAID 5 from Dell for years. Another example of a commonly bad default... EXT4. In that case, it's stable, it's just not as stable or as fast.
-
@scottalanmiller Agreed - I am looking forward to trying this on the Desktop side of things. Having the Fedora guys behind it should help with its implementation.

Hmm... I'd like to think that things on desktops do matter, lol. Kinda hard to use Linux to watch videos or play games if my FS is corrupted and not working.
I do hope it is stable for those who do use it, at least.

Coronavirus: Scotland developing its own contact-tracing app
Scotland is developing its own coronavirus contact-tracing app, which it hopes to have ready for use in the autumn.
It follows the failure of an NHS-branded app in England, which was trialled on the Isle of Wight. On Thursday, Northern Ireland became the first part of the UK to deploy a contact-tracing app. Both Scotland and Northern Ireland decided to adapt software already being used in the Republic of Ireland. Contact-tracing apps are designed to help prevent a second wave of the coronavirus. They work by logging when two people have been in close proximity to each other for a substantial period of time. If one of the users is later diagnosed as having the disease, an alert can be sent to others they have recently been close to, telling them that they should also get tested and/or self-isolate. -

FFS, contact tracing is a not a new thing. It has long been a known useful tool when dealing with contagions
