Release plan

Release plan

[Mike Ramsey]

I was looking at file systems for Linux, Ubuntu in particular.  I really like 
Sun's ZPF.  ZPF's copy-on-write transaction model strikes me as the correct 
way to go.  But ZPF lacks a GNU General Public License which blocks ZPF's 
adoption by the Linux kernel. This led me to btrfs.

I understand that the B-TRee File System is a "copy-on-write file system for 
Linux announced by Oracle in 2007 and published under the GNU General Public 
License (GPL)".

For planning purposes, what timeframe do you see for releasing a stable 
version of btrfs?  I am not a paying customer nor am I an annoying manager.  I 
am just curious as to when I should plan to start paying closer attention.  4Q 
2009? 2Q 2010?

Ext4 is a jornaling file system.  A copy-on-write file system should just be 
so much better.  I find it hard to wait.  :-)

You mean ZFS, but I think everybody who read this "self-corrected" your=
 typo.

=46ilesystems take a long time to mature, btrfs is stable enough for
daily use, has long has you don't use it for sensitive/critical data.
There are still some problems, the most anoying being the premature
"out of space"/"disc full" errors.
I would say that in time for Fedora 12, you will probably have a btrfs
more usable for the common user, but still not advised for the faint
of heart.

Consider the time that ext4 took to mature and for people to trust it.
Ext4 is stable for quite some months, but even now, the majority of
recent distro builds choose ext3 has the default filesystem.

Again.. filesystems take quite a bit of time to mature...

disclaimer: I'm not a btrfs developer, just a entusiast that follows
the developement.


Kind regards,

Yes, I mean ZFS.  ZFS used to be known as the Zettapoint File System.  
I guess my subconsciousness couldn't let go of the "point".

I know.  A schedule has an amazing way of focusing people on what is 
important.  There may be ten things that should be done but not all ten 
things  need to be done.  :-)

Sigh.  Yes, Zettabyte.  I am going to have a talk with my subconscious about
that. :-)
