Subject: 2.6.29-rc1: Cannot loopback mount btrfs formatted file
Date: Sun, 11 Jan 2009 22:44:26 +0100 [thread overview]
Message-ID: <496A683A.6090004@aon.at> (raw)
Since 2.6.29-rc1 contains btrfs I had to try it.
However the loopback mount of my btrfs formatted file fails:
user@host:~$ dd if=/dev/zero of=btrfs.img bs=1MB count=512
user@host:~$ mkfs.btrfs btrfs.img
fs created label (null) on btrfs.img
nodesize 4096 leafsize 4096 sectorsize 4096 size 488.28MB
Btrfs v0.16+da35ab2b0b54
user@host:~$ sudo mount -t btrfs -o loop btrfs.img /mnt/btrfs
mount: /dev/loop1: can't read superblock
Is this version of mkfs.btrfs compatible with the kernel module in
2.6.29-rc1?
Any help is appreciated.
Regards, Peter.
