bcachefs

[mkoniarz]

I'm curious if anyone was testing

https://bcachefs.org/

??

Would anyone be nice enough to prepare ebuild ? (bcachefs-tools)
Or where to start. maybe I could done by myself and share here?

I am looking forward to this.
zfs is out of kernel (been burnt too many times... if my system cannot boot with a stock kernel I am not interested). btrfs seems to have messed up and redhat have their userland ontop of xfs pipedream....

I have just created a 1st pass ebuild

There was this: https://www.theregister.co.uk/2017/11/22/linux_4_14_bcache_bug_destroys_data/

Also, isn't stratis just lvm/dm+xfs?

Not to derail the thread, but openzfs is actually maintained quite well in gentoo. I talk to several gentoo developers (+ foundation members) and users on a daily basis through freenode #zfsonlinux.

Also, openzfs hasn't been maintained by Sun/Oracle since they closed their source in 2005, it's maintained by former Sun employees, illumos (formerly known as OpenSolaris) developers, freebsd developers, linux developers, mac developers, and most importantly, the US Government. (Not to mention countless randoms with no programming experience.)

(I guess technically speaking, Oracle never maintained it, one of the first things they did was to close it, so we shouldn't even be using the O word. )

That said, if you ever do play around with it and have questions, you know where to find me.

I like the sound of it; I've always wondered why people don't talk about the bcache more, since it underpins everything, and has been around since the beginning of UNIX. (cf: Lions, Bach.)

It's the original "page cache", afaic (and I don't think you really need another one in-kernel; just memory areas or "extents".)

Bah. Still waiting for Tux3.

Is bcachefs as painless as btrfs with multi-device storage pools?
I mean with btrfs I can simply add drives to the storage pool, and btrfs spreads the data so that I lose storage space as little as possible while also maintaining redundancy.

totally, this is not production ready but for all intent and purposes it appears stable. It appears to be built on an extremely sound and stable foundation

I'm tempted to build my /var/tmp drive with this to see how it fairs... that does mean I need to fix the ebuild I knocked together for the bcachefs-tools ( https://bugs.gentoo.org/657120 )

as to adding/removing drives, its one of its aims, just don't know the state of it. The goals of BcacheFS seem sound and the development of it seems well thought out. When you look at the so called "next gen FS" for linux, this appears to be ticking alot of boxes after btrfs fizzled out and the relicensing of zfs is nonexistent

yup I saw that. Linus was highly critical of what was provided and also the state it was provided. it is constructive criticism and now its a case of tidying up the code for acceptance. this will take some time BUT its happening
