Error? Ext4-fs (sda6): couldn't mount as ext3 due to feature incompatibilities












2















In recent weeks, when the attempt system boot Ubuntu, the following information appears on the screen with black background:



Ext4-fs (sda6): couldn't mount as ext3 due to feature incompatibilities.
Ext4-fs (sda6): couldn't mount as ext2 due to feature incompatibilities.



Friends, can you tell me how to interpret these messages, and what could do about it?



Thanks

          Apparently you marked the partition as ext3 in /etc/fstab, when in fact it is ext4 ( or you have since converted it with tune2fs ). Change the ext3 designation to ext4 in /etc/fstab.

          • Thanks for your answer. But I found it easier to reinstall the operating system and putting on ubuntu Mate 15.10. Apparently, the new kernel updates were causing me the problem because since that I have not updated the problem didn't appear again.

          I saw this bright red message in my dmesg output and got curious although I am not experiencing any problems. I checked the hint from psusi's answer but /etc/fstab is set to ext4 on my system. After some more research I found this post in the arch forum with an explanation that sounds resonable to me. The gist: The ext-fs driver supports multiple versions and checks which one works if none is specified at boot time. My kernel command line reads root=/dev/xvda ro console=xvc0 console=hvc0 so it looks like auto-detection is required.

            This just happened to me recently after a package upgrade leaving me with a low resolution login screen that wouldn't work. (Ubuntu 16.04)




            • Type Ctrl+Alt+F1 to get a terminal and login via this terminal.


            • Run following commands:



              sudo apt update
              sudo apt upgrade
              sudo reboot



            Hope this helps ...
