How do I set up with ext4?:confused:

[Demz]

have you been reading the Fedora Test List?

How do I set up with ext4?:confused:

when the Install menu comes up hit the tab key and then enter ext4. you will then have to go and modify that partition info for the main partition and change it from ext3 to ext4. I ran ext4 for a while but have gone back to ext3 as LVM will not find other ext4 drives and it prevented me from getting data from an old install..

A directory / boot at 10 works with the type ext4?

No you can NOT boot from an ext4.... Just change the large partition that is used for the files

"as LVM will not find other ext4 drives ..."
That is not an EXT4 issue.
It is because the VolGrop00 default name is the same as the old LVM VolGroup.

All EXT4 f/s s/b able to mount with ext4dev.

Not true.
It was a bug for a few weeks back on F9.

$ mount
/dev/mapper/VolGroup14-LogVol14root on / type ext4dev (rw)
/proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/mapper/VolGroup14-LogVol14home on /home type ext4dev (rw)
/dev/mapper/VolGroup14-LogVol14usr on /usr type ext4dev (rw)
/dev/mapper/VolGroup14-LogVol14tmp on /tmp type ext4dev (rw)
/dev/mapper/VolGroup14-LogVol14var on /var type ext4dev (rw)
### the /boot of this Fedora 10 on ext4 with -O extents as of a few minutes ago.
/dev/sda1 on /boot type ext4dev (rw)

Hello:

SJ

Were you able to successfully install grub on an ext4dev partition with F10 ?

Thanks

Seve

[SlowJet]

No, I haven't tried as I was dual booting with older stuff. Now I'm not.
But when they get the last e2fsprogs, a working patched kernel (408 doesn't boot ext4 or ext4dev) and a patched working anaconda into rawhide in a few days, I plan on doing a net install with all EXT4 with /boot ext4 and grub.and see what happens.

Hello:

I was not able to install grub to ext4 [to date] so I was just wondering if it was my bad luck or just bad timing.

Well, the new patch for ext 4, and the kernel are not working for ext4 or ext4dev
After updating the grub was hosed.
I had a second system to fix things and I've done everything mentioned on the test list

I fixed the /boot with mkfs.ext3, a cp from sdb1 to sda1 and a grub-install /dev/sda --recheck

Then rpm -e kerenl-new
rpm -ivh kernel-new

No boot - /dev/root mounts on /sysroot as ext4dev and stops. (even though fstab says ext4. With ext4dev is says it is no good)

So I'm back to kernel 398, /boot ext3 and /root ext4dev ...

SJ

[SlowJet]

A new attempt for tomorrow.

OK, I got it to work on all the f/s' using kernel 2.6.27-1
Eric actually posted something that said ext 4 /boot does not work.

The trick for going to ext4 from ext4dev on /root, ...

Install new e2fsprogogs, mkintrd,
download the kernel 2.6.27-1 rpm's
reboot into like kernel 398
edit /etc/fstab and change ext4dev to ext 4, and save
install kernel rpms (this will make an initrd
reboot

kernel-2.6.27-3 is broke for intel.

So it looks like a big /, swap combo will not work for ext4 and will affect about half the disto's installers out there in distrowatch.

I think they missed a great opportunity to combine ext4, grub, LVM into an all inclusive f/s like ZFS.
Maybe the next generation will look up more often and see who is doing what?

Now to update the backup system for the next round.

Dear SJ,

At this very moment I have grub booting Fedora 10 installed an ext3 /boot partition and an axt4 / partition. My goal is to have /boot reintegrated to / with grub booting it.

I'm no so sure, but it seems you've been able to reach such a result.

My idea of if would be something like :

Booting Fedora 10 in rescue mode with no chroot of installed Fedora 10.
Manual mount of the /boot and the / partition.
Creation of the new /boot directory in /.
Copy of the former /boot partition into new.
Umount of the former /boot.
Removal of the /boot partition entry in fsab.
Update of the ext4dev reference to ext4 in fstab.
----------------
Possibly update of the UUID partition reference in grub.conf.
Find a way to recreate a correct initrd-xxx.img using mkinitrd.
reinstall grub on the / boot partition sector (not in MBR).
reboot and watch what appends ....

My guess is that I'm failing starting from the second section, at least ...

If my assumptions reveals to be true, could you please clarify what procedure to follow ?

Thks

Sorry, but the conclusions are exactly the opposite.
There MUST be a /boot partition of EXT3 because GRUB can NOT read EXT4.

How do you choose ext4 in the installer? I've tried adding ext4 as both a boot option and as an option to anaconda, but ext4 still does not show as an option.

[SlowJet]

Kernel boot option ext4 on DVD only. Anaconda custom partitioning drop down box for type.

SJ

[robo_mojo]

I see. I was using the Snap-2 CD. It has the ext4.ko module though. hm

Thanks.

All EXT4 f/s s/b able to mount with ext4dev.

I have the drives set up as D320_F10 and D250_F9 for the LVM volumes when I run system-config-lvm It lists both drives. The active one and the other.. When I select the other drive and try to select mount it only shows it as an ext3 drive and there is no ext4 option so I can not mount it.

That gui is NOT current for EXT4. It has only had one patch offered and it is not in the log.

SJ

P.S. Download the new snap3 DVD,
install with kernel line option ext4,
select anaconda custom partitioning,
create a new partition type LVM- PV on un-partitioned space,
Select LVM,
change VolGroupname
add LV and select EXT4 as type,
and your troubles should go away.

SO what do you use to mount the drive. I pulled that rpm form koji and did an install and it still will not work. So without a util for ext4 I have F10 on a drive with ext3 and F9 on a drive with ext4. When I need to copy something I boot to F9 and bring up system-config-lvm and then mount the F10 drive and copy files to it. Though the F9 is BROKEN and I can't really use it. So then I boot back up in F10 (rawhide as of today) and am able to DO ANYTHING that I need. F10 is great except for this ext4 thing.....

Tks
John

[SlowJet]

EXT4 for F9 is very different than EXT4 for F10.
And F10 EXT4 changed as of Kernel 27-3 and mkinitrd 67 and e2fsprogs lastest.
in that ext4dev is now ext4 and only ext4 as a type.

Installed f/s' are mounted in /etc/fstab.
Otherwise you must use the
mount /dev/DEVNAME -t ext4 /mnt/point
or the mapper
mount /dev/mapper/vgname-lvname /mnt/point

mount /dev/mapper/vgname-lvname /mnt/point


mount /dev/VolGroup00/LogVol00 -t ext4 /mnt/test

THANK YOU:) I finally got the drive mounted from F10... Now here I am with an ext3 file system when I really wanted ext4. You wouldn't know how to convert it would you Mr. Wizzard?

tks again
