How many are offering a decent ZFS-based Linux distro?

I was hoping to reinstall my home Ubuntu storage server with a ZFS root, but nope, no ZFS option in the place where you would expect to see it most.
So it supports it, even nicely asks for the passphrase at boot. Be sure to include with the
encryption=aes-256-gcm option from the instructions, as aes-256-gcm is getting some big speed improvements in the upcoming ZFS 0.8.4 release.

Originally posted by Chugworth View PostKeeping system snapshots is a very handy feature, and neither Btrfs or ZFS should have the snapshot performance impact of LVM. Both filesystems were designed from the ground up with CoW support. In fact, I would expect the performance of LVM to be as bad or worse than Btrfs when it comes to keeping snapshots of VMs. In that case, ZFS would be the best choice due to the way it caches data, and also for its ZVOL feature. But you would really need a lot of memory for it to work ideally.
On Linux I've noticed setting vm.swappiness=1 seems to make things a little more smooth under memory pressure. Especially if you have swap on a ZVOL. That is just my own observations tho, I haven't seen that recommended anywhere. ZFS also has no snapshot performance penalty, it takes them instantly and has no real limit on the number you can have. You can snapshot a system every 15 minutes and keep them for a year if you want without a problem. (although snapshot operations, such as listing them will slow down if you have upwards of a few thousand)
As far as what one is better? It doesn't matter if you like Btrfs or what you really use on your home computer or even what people on this forum believe. Enterprises will adopt it and use the filesystem they feel has the best integrity and track record. /shrugLast edited by k1e0x; 08 May 2020, 01:34 PM.

Hopefully BcacheFS can eventually deliver a good CoW FS to linux but till then everyone just have to make do with what came before.
BTRFS vs BCacheFS? Former has had tons and tons of more work and developer effort put into it, they are not even comparable. But it also serves as an example about the nature of non-commercial Linux users. Some new "thing" would always feel more fashionable.
