Oh, again, this debate always goes on and on :) Guys, try ZFS yourselves and come back here :) You obviously haven't seen ARC caching in action. You haven't played with snapshots. You haven't seen what the online compression can do. Etc., etc., etc. There's lots to ZFS, which neither BTRFS

Greetings, - Original Message - There's lots to ZFS, which neither BTRFS will ever even remotely approach. Not really. That isn't to say that btrfs is done or that all of its features, especially those added much later in the development cycle, are stable. So, I don't contend that

Well, innovation isn't about matching features that someone else has just for the sake of having them too, is it? :) What lot of people are missing about ZFS is that it is a self-contained project trying to solve real storage problems. It's not trying to be a filesystem. It is a complete storage

Well, good beginning, but.. as we discussed earlier: in most cases of hosting purposes users need quotes. And quotes work only with ext4. So the only real possible case of usage is ploop over zfs and the only good reason to have zfs here is l2arc cache on ssd or large amount SSD disks in raidz3

When you need quotes and there is only one way to get them... I don't think ploop is about to solve ext4 troubles. I's just solve some troubles (which are common to a lot of file systems). ZFS in this case is more alternative to Parallels Cloud Storage which is closed source and hard to get even

Parallels Cloud Storage is not an real filesystem in old filesystems terms, it based on ext4 locally and provides only remote features like redundancy and multi level caching. On Wed, Nov 12, 2014 at 11:40 PM, Nick Knutov m...@knutov.com wrote: When you need quotes and there is only one way to
