Description Alan Schmidt 2013-07-28 01:43:38 UTC
New, exciting 3.10 kernel just made it to Fedora 19 updates.

One of the new, exciting features is skinny extents, the documentation for which explains that these can be enabled using "btrfstune -x".

However, the current version of btrfs-progs in Fedora-updates is not yet new enough to support this option.

Thanks,

Comment 4 Jan Welker 2013-09-20 13:59:58 UTC
I just enabled the skinny extends on my BTRFS volume and ran a balance to update the old extends. Turns out that this is not a good idea with the current Fedora kernel (3.10.11-200.fc19.x86_64) because the balance seg faults.

We should wait until the kernel patch "Btrfs: fix not being able to find skinny extents during relocate" is in the Kernel.

Comment 5 Eric Sandeen 2013-09-20 14:08:12 UTC
Thanks for testing.  As Josef would say, "welcome to using an experimental filesystem."  :(  (And this was one of my hesitations about plopping new userspace into Fedora, but *shrug* onward through the fog!)

FWIW,

aee68ee5f5427b91be5b23459993134ca64ecf00 Btrfs: fix not being able to find skinny extents during relocate

is in 3.11
