Confirm this bug. I've tried the break=mount option too without success. I can mount an ext3 volume but still not an ext4.
$ mount /dev/sda1 /root results in (obvious as ext3 defaults): EXT3-fs: sda1: couldn't mount because of unsupported optional features (40) mounting /dev/sda1 on /root failed: Invalid argument $ mount /dev/sda1 -t ext4 /root results in (sda1 is ext4): mounting /dev/sda1 on /root failed: No such device In my case I made a conversion ext3 to ext4 using this guide http://kernelnewbies.org/Ext4 that is, $ tune2fs -O extents,uninit_bg,dir_index /dev/sda1 $ fsck -pf /dev/sda1 uname -r 2.6.28-3-generic So I guess it's up to what ext4 features you activate that makes the ext4 device mountable or not in the initramfs shell. However, I can boot up another Jaunty system an mount this "sda1" device there with success so the device itself is ok. -- initramfs fails to mount ext4 root partition or provide user intervention (even when ext4 module is available in the image) https://bugs.launchpad.net/bugs/309762 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
