I've got some filesystems that I want to convert to BTRFS. They currently are Ext3/4 on Linux Software RAID-1. My plan is to break the RAID, convert one of the constituent devices with the btrfs-convert program, and then add the other one via "btrfs device add". How do I get the new BTRFS device to use RAID-1 for data and metadata? Avi, from your talk I got the impression that this was already possible but the man page doesn't reveal how. I'm using btrfs-tools version 0.19+20120328-3 and kernel 3.2.0-2-amd64 from Debian/Unstable. Do I need to get a newer version of the kernel or the tools? PS Great talk Avi, it was good that you had more than an hour. Could you give another talk in Dec or Feb? -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
