Startup Fail | Show Black Screen

Posted on

I edit /etc/fstab and add acl

Then I face the problem
I can access Putty software But can't edit. It's show read-only:

/dev/mapper/rhel-root / xfs defaults,acl 0 0

UUID=8324013d-929b-4c1c-86b8-8540bb9d7732 /boot xfs defaults 0 0

/dev/mapper/rhel-var /var xfs defaults 0 0

/dev/mapper/rhel-swap none swap defaults 0 0

LABEL=/work /work ext3 acl 1 2

My server can't show display. just I can access putty and read this.
