Re: RAID 5/6

This is one of those features that I have been waiting for since I
signed up for the mailing list last year. What source tree is that
code contained in? I would like to start testing it out and helping
out with bug reports(I am only going to use it in a testing VM,
nothing important to work at all). Maybe if I help get it tested and
play around with it I will be familiar when it is really pushed out
and also I can help speed up the development process.
Starting with RAID 1 is an expensive choice for me, I have 8TB of
data(backed up to a friend) that I would have in this array. I was
hoping I could do a RAID 5 of 4 3TB disks and grow it to a RAID 6 of 6
disks in a few months when I need more storage.
