Btrfs Filesystem In Linux 3.6 Kernel Has Big Changes

[johnc]

Solaris may be dead but it still has some very nice features that have yet to be replicated elsewhere. One of those is ZFS.

How sweet, as long as this is pre-alpha crap and not production-ready (ex: tested in critical and big enviroments and debugged like ZFS is) ... it's replacement for nothing.
The patent thing is bullshit, because if the same functionality is implemented, even if it's new code with GPL, it would violate the patents nonetheless ... that's why the ZFS code, which is under the CDDL, has a patent license grant clause

Another Solaris fan that just hasn't gotten over the fact that Solaris/Sun is dead I take it? CDDL was a complete failure as a licence because it wasn't an open license it was basically the same as Microsofts "open" licenses. Sun had the right idea but could never sack up enough to take the company there. BTW btrfs was started by Oracle who also owns ZFS now.

Or perhaps BTRFS is more of a ZFS replacement with many of the features of ZFS, considering the patents and the license surrounding ZFS.

There is a tool btrfsck but it will only tell you your file system is broken. It won't fix it. A working btrfsck has been promised since the begging of time but appears to have fallen by the wayside. That is a blocker for Fedora to make btrfs the default but that hasn't stopped others like Oracle. If your FS is borked there are things you can try though I don't remember the links off the top of my head.But I would try btrfsck first to see what it has to say.

is it no possible to repair a broken Btrfs - had this month's ago after crash, my $Home was close to dead.

@Markore is it possible to use ZFS with Linux - thought only for BSD?

I think there is a tool for repairing btrfs.

Until further notice, use ZFS/ZPL. In production for 6+ years already. (ZfsOnLinux kernel module and Illumos/BSD)
- While BTRFS is re-inventing ZFS, still.

Last I read they had corruption issues with the RAID5/6 code, so it got delayed. I think since then it may have stagnated a bit, so it requires a chunk of work to bring it into line with master, and fixing the corruption issue.

It would be nice if we could get an update on this, though. It's frustrating having RAID 10 eating all my disk space.

ZFS had it in production ages ago.

Send/receive is great, but what happened to raid 5/6 that were due for 3.6?
