I've been testing btrfs send/receive, and to my surprise, the +C (nocow)
attribute I have set on directory for virtual machines images is not preserved.
Is this expected? Having found no information about this issue, I'm asking here.
Info:
$ uname -a
Linux asusntb 3.15.8-1-ARCH #1 SMP PREEMPT Fri Aug 1 08:51:42 CEST 2014 x86_64 GNU/Linux
$ btrfs --version
Btrfs v3.14.2-dirty
Both source and target btrfs filesystems are mounted with the same mount
options:
rw,nosuid,nodev,noatime,compress=lzo,space_cache,autodefrag,commit=60
$ lsattr ~/virtual_machines/
---------------C virtual_machines/archlinux-btrfs.raw
---------------C virtual_machines/archlinux.raw
---------------C virtual_machines/winxp.raw
$ lsattr /media/backup/virtual_machines/2014-08-06/
