It was afternoon when I tried my hands on trying to upgrade my filesysten from ext3 to ext4. I referred to : http://ext4.wiki.kernel.org/index.php/Ext4_Howto#Converting_an_ext3_filesystem_to_ext4 As mentioned… I did the following : <code style="white-space:nowrap;color:#495988;background-color:white;"># tune2fs -O extents,uninit_bg,dir_index /dev/<em>VolGroup00/LogVol00</em> <code style="white-space:nowrap;color:#495988;background-color:white;"># e2fsck -fD /dev/<em>VolGroup00/LogVol00</em> After quite some time, the procedure finally completed. I was so delighted that I did a sytem reboot to find that my system won’t boot. The reason, I didn’t update my kernel ramdisk image, and it tried to mount the / partition as ext3 and failed as the partition has already become ext4....

I am using Fedora 10 and I was running the kernel 2.6.27.15-170.2.24.fc10.i686 and I was happy until I did a ‘yum update’. My kernel got updated to kernel 2.6.27.19-170.2.35.fc10.i686, and then the system won’t boot the latest kernel. While booting it gave a mesage : Unable to access resume device (/dev/dm-1) mount : could not find filesystem ‘/dev/root’ I wondered what had happened? But, the old kernel 2.6.27.15-170.2.24.fc10.i686 seemed to work perfectly....
