Re: Ext4 vs Ext3, is it really stable ?

Yes I know, I am using my own 2.6.28 compiled kernel (Debian way
compiled ;) ). I know this problem but at this moment is a secondary
problem, I think a lot of linux distributions will launch new versions
with ext4 capable kernel.

My doubt is about the stability, is it really for production use ? I
want to know that because I am really interested in use in production
use (like most of us, I think...). I have done some tests about crash
recovery and I have seen a good response. I have copied a lot of files
and I have cutted power on server. The filesystem is OK after the power
is connected again. I want to try with a mysql server on a intensive
inserting/writing, I think this is a good tes to do, because a database
server needs very reliable filesystem.
I'm having a good experience with it, but I would use it at least with kernel
2.6.28 and up (when it went from ext4dev to ext4). The problem is that ubuntu
and debian live and rescue cds are kernel 2.6.27 and 2.6.26 respectively so
they won't be able to boot into the system.
Also if you want boot on the ext4
partition you will need to use grub2 as grub doesn't support ext4.
Another good tip to save in my mind.
Yes, It could be the reason of the problem that someone had with his
partitions. His partitions locked for a few seconds before they gave a
thing is that laptopmode doesn't seem to work as well with ext4 as of now.
It is a good thing to investigate, because it could be a hidden bug.
