Fedora 16 To Use Btrfs Filesystem By Default

dkd903 writes "According to proposals for Fedora 16, Btrfs will be the default filesystem used in that release. The proposal has been approved by the Fedora Engineering Steering Committee. In Fedora 16, the switch from EXT4 to Btrfs will be a 'simple switch' — it means that major Btrfs features such as RAID and LVM capabilities will not be forced onto users."

Re:I wonder if they have a working fsck yet?

Is there a need an fsck? For example, ZFS doesn't have one and I haven't heard of anybody working on it (or of anybody actually wanting one).

Um, yeah, read zfs-discuss. There are helpful folks on there who help people recover their ZFS volumes, but having a tool to do it would be much better.

fsck for ZFS or btrfs means something different than it does for ext* but it's still needed. I just had a client's new 18TB ZFS zvol go TU when the power failed and the UPS->host communication wasn't properly connected. Fortunately it wasn't very important and the important zvol wasn't active when the power failed.

btrfs will be better than ZFS for many use cases once the fsck is stable. For others ZFS will remain better, but you better have battery-backed disk cache or a monitored UPS (neither of which are appropriate requirements for large swaths of the Fedora user base).
