Proper way to format BTRFS in 1.7?

Hi all,

In the light of my recent challenges from a btrfs upgrade, I've decided to completely destroy and rebuilt the RAID and filesystem on my 1.7 OMV.

Right now, the RAID5 is building (about 2 hours remaining), so I figured I'd ask what the 'right' way is to format the resulting volume with BTRFS is? I don't see that format available in the pulldown (only EXT4/3, XFS, and JFS). I understand that BTRFS is not fully supported in the WebUI yet, so I wanted to see what the advised way to do this was so that I'd have a maximal chance of things "just working" (as one would want from storage) in the future.

Thanks!
Mike

Fair enough. Is there any kind of roadmap showing when it will become available?

Hmm. I don't see the dev section to browse, so let me ask - what is the ZFS roadmap? I came to BTRFS because ZFS was not available either, and it sounded like BTRFS was more 'baked-in". I'm fine with either - just would like one or the other.

Thanks for the input, both of you. I'll go back to ext4 now, and hope that my NFS problem goes (back) away as a result. I was just hoping to get on an 'advanced' filesystem sooner than later as the more data I build-up, the harder it is to transition in the future...

I created a new RAID across 4 disks - is this missing ~1TB to be expected?

The various partitions of 682+682+246=1.6TB.

This is 4x2TB drives. This is probably the parity store, but looking for confirmation before I spend the next 6 hours restoring data. That's all.

So, when I click Filesystems, I should only see the p1, p2, p3 filesystems in the dropdown, and not the 5+TB? I don't recall seeing these 'minor' partitions on my previous install... I'm dd-ing the thing.

I'm seeing what's in the screenshot above

That did it. I did a dd on all four drives for a while to zero them out, then OMV didn't show the broken-up chunks in the screenshot any longer and I have a nice, single volume.
