Is ext4 file system supported on fedora 8? If yes, then how do i enable it?
I am unable to see format command for ext4. I can see only mkfs.ext3 and mkfs.ext2.
Fedora 8 was released on 8 November 2007
ext4 went stable on 21 October 2008
So no, it did not include ext4 support.
I would say it's time to upgrade your system but honestly that time was 6 years ago already. :-)
Check when fedora 8 and ext4 came out and you'll understand.
Ext4 support was experimental starting from fedora 9. It came being the default filesystem since fedora 11.
Also note this is an 7 years old distribution and fedora technical support is limited to Fedora 20 and 21.
