I just want to emphasize that I didn't want in any way to say anything against a great work Josef does ... I totally understand that every software has bugs, and well when the software is filesystem, fun things happen :).

Does btrfs-progs-0.19 work with both versions of the disk format? If so it might be worthwhile pushing them to rawhide before hand.

Btrfs has been surprisingly good for me, no problems outside claiming the partition was full when there was 25gb left (on a 120gb drive). I say bring on this update, hilarity and dataloss, they do mix no matter what sanity says. - David -- fedora-devel-list mailing list fedora-devel-list@redhat.com https://www.redhat.com/mailman/listinfo/fedora-devel-list

BTRFS in 2.6.31-rcwhatever
Hello, It seems there has been some confusion about BTRFS and the new format, so let me try and clear some things up 1) Btrfs is an experimental and unstable fs that is to be used for testing only as it could eat your data. 2) Btrfs is an experimental and unstable fs that is to be used for testing only as it could eat your data. 3) Btrfs is an experimental and unstable fs that is to be used for testing only as it could eat your data. Ok now that we have that out of the way, 4) The merge window opened last week for 2.6.31, at which point a new disk format for btrfs was sucked into the kernel. 5) This new disk format is _incompatible_ with older kernels, which means that older kernels will not mount a fs with the new format. Nothing bad will happen if you try to boot into an older kernel, you won't lose data, it just won't work. 6) This new disk format is automatic. As soon as you boot into the new kernel, your filesystem will be automatically converted to the new format. There is nothing you can do, so if you don't want the new format, don't run the new kernel. At some point in the next few weeks this kernel will land in rawhide. I will try and make sure btrfs-progs-0.19 goes out at the same time. The new btrfs-progs isn't essential for running the new format, so if you just install the kernel you will be fine, but obviously some of the commands may not work properly. So if you installed onto btrfs, be careful about going to rawhide, since you will not be able to go back if you do. Btrfs will not be as stable as ext4 currently is for at least another year, so it is still very much just for testing. I am very interested in hearing about bugs and getting them fixed, however there will be little to nothing that I can do if you lose data.
