From mboxrd@z Thu Jan 1 00:00:00 1970 From: Chris Ball Subject: Building a RAID post-mkfs? Date: Fri, 16 Oct 2009 13:54:10 -0400 Message-ID: Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii To: linux-btrfs@vger.kernel.org Return-path: List-ID: Hi, I installed btrfs to one disk using the Fedora 12 installer; it doesn't allow any configuration of the mkfs command by the user, so it wasn't possible to mkfs with more than one disk. I'd like to add a second disk, with either RAID0 or RAID1 between the two -- the equivalent of "mkfs.btrfs -m raid0/1 -d raid0/1 /dev/sda /dev/sdb". Is it possible to create this non-destructively now? If not, should it be? What would the implementation look like? Thanks, - Chris. -- Chris Ball One Laptop Per Child
