Description of problem: I'm unable to create a snapshot Version-Release number of selected component (if applicable): btrfs-progs-0.19.9.fc12 kernel-2.6.32.9-70.fc12 How reproducible: Always Steps to Reproduce: 1. Create a 300MB btrfs file, format and mount as a loop device: dd if=/dev/zero of=btrfs.img count=300 bs=1M losetup /dev/loop0 btrfs.img mkfs.btrfs -L test /dev/loop0 mount /dev/loop0 /mnt/btrfs/ 2. Create a snapshot: btrfsctl -s snap0 /mnt/btrfs/ Actual results: ioctl:: Inappropriate ioctl for device Expected results: Create snapshot Additional info: # modinfo btrfs filename: /lib/modules/2.6.32.9-70.fc12.i686/kernel/fs/btrfs/btrfs.ko license: GPL srcversion: 515D00B63448802E7928F98 depends: libcrc32c,zlib_deflate vermagic: 2.6.32.9-70.fc12.i686 SMP mod_unload 686 As reported in http://www.linuxquestions.org/questions/linux-software-2/btrfs-filesystem-problems-with-btrfsctl-when-shrinking-and-defragmenting-fs-723177/ the problem might be a version mismatch between the kernel module and the utility package. But I don't know how to check the kernel module version!
I just noticed that there was a duplicate bug. I didn't find it neither looking with google nor with the bodhi "bug reports" function. I'll close the bug, sorry for the noise. Mario *** This bug has been marked as a duplicate of bug 503726 ***
