I was wondering if anyone here has attempted the new "COW filesystem for Linux that won't eat your data".

It's supposedly has been stable since the start of 2023. I'm willing to give it a try on Arch, but before I do, I'd like to hear if anyone has faced any issues with it.

I am unfamiliar with this filesystem, and am curious about it. Could someone explain to me its benefits over btrfs?

[–] actual_patience@programming.dev 7 points 1 year ago (2 children)

From what I understand:

it has all btrfs features
it's as performant as ext4 (with COW enabled)
it's more stable than btrfs
it has built-in encryption, (no LUKS needed)

The page in Gentoo explains it's features well

It's still missing the send and receive features from btrfs. And while they say it's more stable than btrfs, it's yet to prove itself (through widespread use), and is marked as experimental in the kernel config.

I recall snapshots not being quite as cheap as on ZFS.

Is there an article I can refer to? This isn't an easy topic to search for.
