I''m trying to create a multi-device filesystem on top of regular files (not actual disks), and mount that to a loopback device. For a filesystem created on a single file, it works fine, but for a filesystem across multiple files, it doesn''t. dd if=/dev/zero of=img1 bs=4096 count=65536 dd if=/dev/zero of=img2 bs=4096 count=65536 dd if=/dev/zero of=img3 bs=4096 count=65536 dd

Hi, Let me know if this is the wrong place to ask... I''m using Fedora 12 x86_64, mostly with the newer 21.6.32 kernel, and have a single btrfs filesystem within a 120Gb partition. I''d like to extend the space btrfs can use. One option is presumably add a new device to btrfs, but I was hoping to simple resize the existing partition to say 160Gb. With ext4 I might do

...rfectly reproducible, no matter what RAID type I specify (raid0, raid1 or raid10). I used the latest version from the btrfs-unstable and btrfs-progs-unstable git repositories. When using real block devices, however, everything works fine.
