Hello, Does anyone know when RAID 5/6 are planned to be included in the Kernel? I am starting to buy parts for my next computer and would very much like to use BTRFS because I want a FS that can grow and also recover from undetected read errors - it will be large enough that these are possible. I''m hoping that it will be available for use in the coming months.

This assumes that you can manage to use RAID-1 in the first place and expand later.

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.
