Hi ,

I am using RHEL7 and am facing problem while booting. Its giving a error message as shown in attached image. As far I know its related with some mounting issue.

just for reference I am giving "df -h " output and /etc/fstab/file and also all hard disk detail.

/dev/mapper/rhel-root   50G   11G   40G  21% /
