I always thought btrfs was the answer (also brought to you by Sun) for the same feature-set as ZFS, but in a linuxy way.

I hail all progress made on this front. I dinked around with running a failover ZFS before, and I can say it is pretty awesome stuff (as is btrfs).

Competition in the filesystem field is slow going (as it should be), but fierce. That's the ways I's likes it.

btrfs doesn't have anywhere near the same featureset as ZFS. Here's a few examples:
ZVOLs for virtual machines. I extensively run VMs under Linux, they all need a block device(ideal) for their disk IO performance. ZVOL
is perfect, add in easy ZFS replication and I can back up virtual machines every day offsite, with absolutely no service interruption. BTRFS
is ages behind in this category.

The 'linuxey' syntax of btrfs is cute and all..but exactly why are my snapshots mounted, and read-write? I keep A LOT of snapshots, and having my mount tab polluted by thousands of entries not to mention users being able to write to the things?

Also I found the syntax of ZFS completely intuitive. tank/movies is my movies filesystem, tank/movies@20140701 is my 2014-07-01 snapshot of movies. All commands reference snapshots as a clear subcategory of it's parent filesystem. If I -r recursively remove a snapshot, I can take out a bunch of depending snapshots wihtout screwing around with them individually.

In short, ZFS naturally seems to work like I do... In my opinion BTRFS should mimic the syntax instead of going it's own way, and differentiate in the implementaiton.
