Resolution

Note: Before proceeding, ensure to take a snapshot or backup of the vCenter Server Appliance 6.5.

  1. Reboot the vCenter Server Appliance 6.5 and immediately after the OS starts, press e to open the GNU GRUB Edit Menu.
  2. Locate the line that begins with the word linux.
  3. Append the following to the end of that line:

    systemd.unit=emergency.target

  4. Press F10 to continue booting.
  5. Find the filesystems by running the command:

    :/# /bin/sh
    :/# /bin/mount
    :/# blkid


    Note: You will see the list of devices mounted with the disk uuid.

  6. Execute the command:

    :/# e2fsck -y /dev/sda3

    Note: The nodes will be fixed automatically as we have given -y.

  7. Power off the vCenter Server Appliance.
