All,
After reading this:
http://ext4.wiki.kernel.org/index.php/Ext4_Howto#Converting_an_ext3_filesystem_to_ext4
do you have any experience with mounting your ext3 filesystems using
the ext4 module? Is the performance improvement noticeable?
I haven't tried it directly, but I remember forgetting to compile-in
ext2 support and then being unable to mount /boot (ext2) despite having
ext4 support
And how about using the extra options:
|# tune2fs -O extents,uninit_bg,dir_index /dev//DEV
/|
I use all those, except uninit_bg without a problem.
In fact, I use dir_index,filetypes,sparse_super,acl,user_xattr without a
problem.
But I have noticed that sometimes some mount options in /etc/fstab can
prevent mounting or cause an error and mount "/" in ro mode, not always
the same. I have noticed that I can mount ordinary partition with one
option combination but fail when mounting /dev/md2 in precisely same
way. Basic "noatime" works always,though.

How stable do you think that the ext4 module actually is? (using
recent kernels, e.g. 2.6.29)
I had many problems ( files dissapearing after reboot, other files
getting strange content etc), but after ext4 problems were published
about and corresponding pathes in kernel everything works fine for me. I
haven't had a single issue after that, and I'm using it on two lightly
loaded servers and my workstation.
