Hi,
btrfsctl is deprecated, why you're adding new options to it? :)

Well, I did not know that it's deprecated ;-)
Neither the manpage nor the program itself said so and the messages
annoyed logcheck...

Hi,
there is a patch that marks it deprecated:
http://www.spinics.net/lists/linux-btrfs/msg06625.html
But it's not in git yet :/ Last commit is from oct. 2010, hopefully all new
patches
will be pulled soon.

Hi,
I wanted to create a new btrfs fs for my backups.
When trying to mkfs.btrfs for that device, I'm getting
"error checking /dev/loop2 mount status"
With strace I see where the problem is:
lstat("/dev/disk/by-id/ata-INTEL_SSDSA2M160G2GC_CVPO939201JX160AGN-par",
0x7fffa30b3cf0) = -1 ENOENT (N
I was able to create the fs with the --force options. But that bug should be
fixed,
too :)
Is that link maybe too long? It is created by udev, and there was never a
problem
using that link.
Regards,
Felix

It was a simple:
mkfs.btrfs -L backup -d single /dev/loop2
But it also happens without the options, like:
mkfs.btrfs /dev/loop2
/dev/loop2 is a loop device, which is aes encrypted. The output of "losetup
/dev/loop2":
/dev/loop2: [0010]:5324

Hi,
no :) loop2 is the decrypted device.
A small example:
/dev/sda1 is encrypted. Then you run losetup with some options and /dev/sda1,
enter
the password and after that /dev/loop1 will be created.

fdisk -l /dev/loop1

Any idea how this is handled? I would be interested in the answer as well.
Thank you in advance, Clemens

Hello,
