Is it currently possible to remount subvolume (not the whole filesystem) with nodatacow?

If so, please tell me, what is the first confirmed kernel version, which supports this. Or at least, is it available on Kernel 3.5. I know, that it is possible to assign nodatacow attribute to files with "chattr +C ", if the file has zero length. Thank you -- Adam Ryczkowski +4

How to clone btrfs partition?

ed that I need to use snaphot (created with the "-r" switch). So does it mean that I need to make a recursive search for each read&write subvolume on the file system in order to make a read-only snapshot, so I can clone the whole partition? Or is there a more simple approach?

Why does "btrfs send /mnt/btrfs-root" fail with "ERROR: /mnt/btrfs-root is not read-only." even when mounted with option "ro"?

nt/btrfs-root/foo I get "touch: cannot touch `/mnt/btrfs-root/foo': Read-only file system" My btrfs --version reads Btrfs v0.20-rc1-56-g6cd836d And uname -r 3.7.8-030708-generic Do I miss something obvious? Or should I wait until next kernel version? -- Adam Ryczkowski +48505919

Is it possible to use send & receive features to clone the btrfs partition efficiently (including all snapshots inside)?
