I've used ZFS and BTRFS under Linux, though I haven't tried native ZFS<br>
encryption yet. I have used both ZFS and BTRFS under LUKS encryption too.<br>
<br>
Both BTRFS and ZFS work so much nicer than mdraid when it comes to<br>
spanning across multiple disks (though beware that BTRFS still isn't<br>
production safe for RAID5/RAID6).<br>
<br>
If you want to use a multi-disk storage array, ZFS and BTRFS are both<br>
superior options to MDRAID.<br>
<br>
However ZFS is just straight better and easier to maintain than BTRFS,<br>
especially now that native encryption is a thing (something BTRFS sorely<br>
lacks).<br>
<br>
<br>
<br>
Here is my disk topology for my 4 disk RAID10 setup under BTRFS.<br>
<br>
Disk 1 - LUKS - Btrfs --\ /--Btrfs subvolume<br>
| |<br>
Disk 2 - LUKS - Btrfs --| |--Btrfs subvolume<br>
|--- Btrfs volume --|<br>
Disk 3 - LUKS - Btrfs --| |--Btrfs subvolume<br>
| |<br>
Disk 4 - LUKS - Btrfs --/ \--Btrfs subvolume<br>
<br>
To be honest, it is a pain in the arse to mount an encrypted BTRFS<br>
volume this way. You need to unencrypt all four drives first, and then<br>
you need to mount it. But at least once its mounted, the subvolumes are<br>
already set up.<br>
<br>
If I need to replace a drive (and I've had to replace drives) it is also<br>
a pain in the arse due to having to deal with both Luks and BTRFS.<br>
<br>
Encrypted ZFS would simplify this setup enormously.<br>
<br>
When I need to replace my drives, I will be switching from BTRFS to ZFS.<br>
