That all looks correct to me. Did resize2fs run successfully with no errors? Did you try it again? This volume is ext3 and not ext4? On 5.x to use ext4 you'd need to use resize4fs not resize2f... [by TrevorH]
IS there any way to convert ext4 extents back to mapped inodes or what they were before. I just don't need large file or huge file support and all that comes with ext4 including overhead. EXt3 does me just fine on my old IDE. It's only 300 Gb. And I haven't used nearly that amount about 5% of that. I use ext3 on a USB drive.
How To Convert An ext3/ext4 Root File System To btrfs On Ubuntu 12.10
ext3 and ext4 file systems can be converted to btrfs. For non-root
file systems, this can be done online (i.e., without reboot), while for
root file systems we need to boot into some kind of rescue system or
Ext4 fiflesystem includes multiple improvements in terms of filesystem performance. It this article we show how to convert an ext3 fileystem to ext4 and thus enabling some of the ext4 performance enhancement features.
I was wondering if ext4 is stable enough for production use? I have read through most of the ext4 reviews but they are a little dated, most of them referring to ubuntu 9.04 and the 2.6.28 kernel. Any thoughts?
I am trying to convert a root ext3 filesystem to ext4. So i ran
tune2fs -O extents,uninit_bg,dir_index /dev/sda1
Then I changed the filesystem type from ext3 to ext4 in /etc/fstab and then added rootfstype to the grub config files. I've rebooted assuming that the kernel would just fsck on its own but it hasn't come up (headless remote machine).
I have a data only USB HDD I recently switched to EXT4 after verifying on multiple machines it would be read-able. After the conversion, I realized that my router wouldn't mount it. Of course, it was "supported" in the sense that it's supposed to work but the manufacturer can't get their story together.
