Hallo,

if I've understood some mails in this list correct, then btrfs needs a  
character device "btrfs-control"  with the ID 10:55

When I look for this device in

        /sys/class/misc/btrfs-control/dev

I see 10:234

And when I run the command

  mkfs.btrfs -d raid0 -m raid1 /dev/sda1 /dev/sdc1

I get the error messages

  failed to open /dev/btrfs-control skipping device registration

---

  ls -l /dev/bt*

shows

  crw-rw-rw- 1 root root 10,55 2. Apr 17:55 /dev/btrfs-control

---

Kernel 2.6.38.1 (self made), no udev, no initrd, no tempfs. btrfs from  
nov. 2010

What goes wrong?


Viele Gruesse!
Helmut
