Hi, all. I'd never done RAID on btrfs before, so bear with me if I'm missing something obvious. I just created a RAIDed btrfs partition with mkfs.btrfs -m raid10 -d raid10 -L bigguy /dev/sdb /dev/sdc (I also did the same, but with RAID-1, getting the same results I'm about to outline.) That's two 3-TB disks; since they're RAIDed, I expected to wind up with ~3 TB of free space. But df reports 5858378624 available. Knowing that df and btrfs don't always see eye-to-eye, I copied over a 350 MB .avi, and fired up btrfs-show, which came back with: Label: bigguy uuid: 5e062e02-f55e-4d7f-866c-3b851b3c6e02 Total devices 2 FS bytes used 350.57MB devid 1 size 2.73TB used 1.27GB path /dev/sdb devid 2 size 2.73TB used 0.00 path /dev/sdc That don't look very mirrored to me. All the instructions I found said I should just mount /dev/sd(b|c) singly; is there, instead, a logical RAID partition I should be mounting? Or... is there something else I'm just missing?
