Ext4 was very new around 2.6.27,. The kenel is likely refusing to |
2 |
mount the filesystem because the kernel driver is experimental (old) |
3 |
and the filesystem was created when a different kernel was loaded (non |
4 |
experimental ext4). Using the old driver could compromise the |
5 |
integrity so the kernel refuses. You might have better luck with a |
6 |
more recent kernel. |
