ext4 on Fedora 10 with kernel 2.6.27.38-170

Post by Basher52 » Tue Dec 15, 2009 12:17 pm

I'm about to switch some disks due to some sector errors that I've seen lately so I wonder...

First, is this possible with this kernel? I just read that it wont.
if I can do it, how do I format it?
I can't use fdisk or parted cos it seems that they only see 2Tb and not the full 3Tb. Can I skip the partition all together maybe? Do I really need that?

parted should create a 3TB partition:

I don't think ext4 support showed up until Fedora 11 and the earlier versions were not very stable. I would consider xfs if this is for a media server. ext3 should would work too though. Hopefully you never have to run a file system check though because that would probably take an hour on such a large file system.

I created xfs volumes before and you might remember that too with your help. So what is best, upgrade to Fedora 12 first and then use ext4 or use xfs and then later upgrade?

My xfs I use now havent had any problems (yet, knock knock :P)

I just installed 2 1TB drives in my desktop the other day (Fedora 12). I mirrored them with Linux RAID and then put a logical volume on top of that with an ext4 file system on top of that. That was my first ext4 file system. If I were creating something from scratch I would use the latest OS depending on what you are building. I think xfs and ext4 are very similar in performance and if you are going with F12 ext4 is the default FS so it would probably be the all around best choice. I did a little more digging on the ext4 corruption stuff and I don't think it's a widespread issue.

OK, then I'll set a F12 machine up later cos I gotta test some applications of that before I go ahead with the upgrade.

I also read something about data corruption with ext4, but they wouldn't let it out if it was that of a big deal right? didn't they hold it back a while just cos of things like this?

I read some back and forth about Linus not being too happy with either ext3 or ext4 so... :)

Not necessarily. Linus isn't happy a lot. That's a good thing though, means improvements.

I just tested F12 on a separate machine and... hmm...

I think I only upgrade to F11 cos F12 is for me too unstable it seems.
Not even FF can work properly, but I saw some post in here that FF has some problems but if THAT can't work, can I really trust the rest :P
and if I go for F11 I got about 1 year to upgrade to 12 so...
