ext3 support in kernel

Hi!
I recently installed the latest DSL release (3.0.1) and formatted my partition with the ext3 filesystem. However, on boot it says it is mounting and ext3 partition as an ext2. Other than that, if I try to mount another ext3 partition anywhere, it says the kernel has no support for this filesystem... As far as I could check, there's a module for this filesystem type in /lib/modules/linuxXXX

So, how do I activate the support for ext3 fs on DSL?

Thanks!

Ok, I just figured out the problem of not being able to mount other ext3 partitions. However, DSL persists to mount my root filesystem as ext2 instead of ext3 on boot, saying something like "mounting ext3 as ext2"...

Any help?

Thanks!

I don't think there ever has been ext3 support.

However, ext3 is backwards compatible with ext2, and is mounted as such. See < http://en.wikipedia.org/wiki/Ext3 > for more info.
The one key feature would be journalling.

No ext3 support in DSL?

I really think DSL should have ext3 support, since the advantages over ext2 are very significant. The "install to hard drive" script/program asks the user if they want ext3 or ext2, so it might as well actually be included

HOWEVER, if you wanna get rid of the error, do this:
1) (as root, probably) do this: "tune2fs -O ^has_journal /dev/partition"
2) edit your /etc/fstab file so that your partition is being mounted as ext2 (in other words, replace "ext3" with "ext2" as necessary)

And enjoy the checking for filesystem integrity for minutes on bootup if the power gets cut! (But hey, at least you're warning free now)

:laugh:

EDIT: If you get an error that the partition must be mounted in read-only mode, do this before running the tune2fs command:
"mount -o remount,ro /dev/partition"
then, if you'd like
"mount -o remount,rw /dev/partition" to get it back to normal (ie no reboot required)
