btrfs suitable yet ?

Hi

If i do a new fedora 12 installation on my pc is the btrfs with the latest kernels (.31/32) reliable for a daily usage yet and can grub boot from btrfs?
will i benefit from further changes on the fs or do i have to re-format my partitions again once it becomes the new default fs in fedora ?

ext4 looks a bit abortive after the last changes if one can trust benchmarks like on phoronix:
http://www.phoronix.com/scan.php?pag...then_now&num=1

so i'm unsure what fs to use for my hdds, any suggestions ?

i would probably stick to ext3, its a proven trusty Filesystem IMO. i think you'll find F13 will have better and or more support for btrfs in Grub

i dont think btrfs will be somewhat usable untill F15 comes out and or stable at that point. it might have nice features but it all depends if Grub can recognise that filesystem . an i dont thiunk they'll do much more work on Grub-legacy. i think they'll put all there effort into Grub2 wwith these new filesystems

i could be wrong though

I have been using BTRFS since it was added to mainline. It is FAST. As with any new FS I do not recommend it for production systems, but if you want to try it at home go for it. I love it.

Did I mention it's FAST? Snapshots rule too. It's too bad ZFS isn't coming to linux anytime soon, but I have to say that BTRFS is the next best thing. Although the developer has stated that future development will not require a reformat of your drives unless there is a MAJOR bug that cannot be fixed, it is still possible so keep that in mind. But for the performance and because I like to tinker with new stuff, it is well worth the PITA of performing a RE and RE of my data because of a future bug. I like the fact that it also uses raid 10 instead of the raidz implementation of raid 5. IMO and experience, Raid 10(1+0) is faster.

That being said, no grub1 cannot boot btrfs but an ext2 boot partition solves that. then just add the BTRFS and dependant modules to initrd and you're good to go! As for grub2 I do not know if it's been patched for btrfs yet or not.

Have fun with the future of file-systems, and happy snapshotting!

Some info on Fedora 13 BTRFS Features.

Also keep your eye on NILFS.


Giggity!
