Is ext4 okay to use?

I posted a question thread in the Ubuntu section since I have a problem following a procedure. I don't know but upgrading to ext4 in Ubuntu is such a pain.

And I wonder whether upgrading to ext4 in Ubuntu 9.04 is fine.

Or should I just stick to ext3?

ext4 is better than ext3. So updating to it would be good.

I see. But sorry if I'm being very rude but could somebody check my other thread, please? This ext4 issue is getting very irritating and I'm quite lost.

Thank you.

Given that you asked e2fsck to fix errors, it doesn't make a lot of difference since the changes have been made. That said, I don't see any great issue in the output. From what I've read, you would expect fsck to fix various "errors" since it needs to "correct" for the file system changes.

Time to mount at ext4

So,

Code:

/dev/sda1: Group descriptor **** checksum is invalid.  FIXED.
/dev/sda1: 112212/30154752 files (0.1% non-contiguous), 2468594/120607979 blocks

This is okay?

I would assume so, but as I said, you've done it now anyway, so I don't see you undoing it in any case.

From the wikipedia article on updating:

Quote:

After running this command, you MUST run fsck to fix up some on-disk structures that tune2fs has modified:

So it's clearly expecting some form of "error" to be found.

Edit - if you want to check, you could always run fsck again.

I see. So e2fsck is about a checking and fixing the file system, if I'm right.

Anyway, if I'm going to installed Ubuntu 9.04 from scratch (with a disk), is it necessary to upgrade my GRUB?

billymayday · 05-28-2009, 12:46 AM

I'd find something on the Ubuntu site about that one - you need to know what version of grub 9.04 comes with.

How will I do this in a nutshell?

Are certain GRUB versions only compatible with ext4?

If only Canonical could make an ext3 or ext4 option during the installation, it would be more straight forward. Maybe if someone make a GUI-based application for 9.04 to make this easy. Wishful thinking.

ext4 is still very new. My (strong) advice would be to ignore it until it becomes the default.
By then it'll be debugged (we hope).

So will it be very ok to use Ubuntu 9.04 with ext3 and be safe?

Are there huge issues with the relatively new ext4?

This is interesting.

Well I am using Ubuntu Jaunty BETA with ext3 and still not very unstable. ext3 is stable and there is no harm in sticking with it till ext4 has been extensively tested.

billymayday · 05-28-2009, 01:38 AM

try reading http://blog.fusi0n.org/linux/convert...ntu-904-jaunty

Standard grub does not recognise ext4 (unless there has been a quite recent release)

Why are you in a hurry to move to ext4 in any case?

Dr. ROX · 05-28-2009, 03:39 AM

I'm using ext4 about 2 months and got no problems with it. So i guess its ok to use.

It'll be default in the upcoming Fedora 11. So I guess it should be okay to use.

Also I did some tests myself, as I am offering ext4 as an option in my own distro, and so far I am pretty happy with it.
