Short story: I used one of the various (identical) guides to attempt to migrate my existing ext3 file system to ext4. After what I believed to be a success, I rebooted, and for good measure, checked in the System Monitor after login, which read the filesystem as ext3. What did I do wrong?
Stepwise process:
1) Upgraded to 9.04 from 8.10 (64bit) using the recommended "network upgrade" method (http://www.ubuntu.com/getubuntu/upgrading). Everything seems to work just fine.
2) Downloaded & burned the 9.04 live CD (ubuntu-9.04-desktop-amd64.iso.torrent).
3) Booted to the live CD. I'm not sure how else to use the tune2fs commands, since they need the filesystem to be unmounted; I assume this is the correct procedure.
4) used the following command... I didn't include the "#", as I though it was a comment item; if I should include it, what does it do?
tune2fs -O extents,uninit_bg,dir_index /dev/sda5
where sda5 is the filesystem with 9.04. (I have a dual-boot system, and if I'm reading the partitioner correctly, grub & the and the boot are sitting on the ntfs partition). I checked the partitioner, which now read sda5 as ext4. Seemed like a success...
5) I followed up with the command (again no "#")
e2fsck -pDf /dev/sda5
It found and autofixed the file system discrepancies.
6) After the fsck check finished, I rebooted, removed the live CD, and logged into 9.04 just fine, but the system monitor still shows the filesystem as ext3.
Suggestions?
