I had downtime in my lab due to an power failure which resulted in a boot failure of my VCSA 6.5 appliance. Looking on the console showed me a “[FAILED] Failed to start File System Check on /dev/dis…uuid/uuid. See ‘systemctl status system-fsck-root.service’ for details.” message. Therefor it booted into ‘Emergency Shell’ or ‘Emergency mode’.

I ran the command ‘systemctl status systemd-fsck-root’ manually. This showed me that the ‘/dev/sda3’ partition was having issues.
UPDATE: It also states “RUN fsck MANUALLY”. I did not notice this the first time

In the end I received the message ‘FILE SYSTEM WAS MODIFIED’ and tried to reboot. The reboot command gave me an error so I went through the ESXi to reset the virtual machine. Afterwards I was able to login again.
