Hi,
"An error occured during the file system check.Dropping you to a shell.The system will reboot when you leave the shell.
Give root password for maintenance ( or press Control+ D for normal starting ) :
bash:whoami :command not found
bash:mesg:command not found
bash:dircolors:command not found
root@abc

asswd root
bash

asswd :command not found "
When I enter the root password in the "Give root password for maintenance ( or press Control+ D for normal starting ) :" and press enter, I was bring to the shell prompt but it does not allow me to change the root password.Is there limitation on the maintenance mode?
