I was unable to login onto my Webclient and when I checked the console I was greeted with this error on my vSphere 6.5 VCSA and PSC appliances. Looks like there was a storage outage or interruption overnight and my datastores went offline momentarily. 

I Rebooted my PSC and the following errors were listed.

Error Dependancy failed for /sysroot

Error Dependancy failed for Initrd Root File System

Error Dependancy failed for Reload Configuration for the Real Root

Generating “/run/initramfs/rdsosreport.txt”

Entering Emergency Mode

The first step was to run

fsck /dev/sda3

and answer Y to all the questions.

I then rebooted the VM. After reboot,  I  received these errors but was given the option to access the shell which was a slight improvement. 

Failed to start Network Service

Failed to start Update UTMP about System Runlevel Changes

Welcome to emergency mode. After logging in type “journalctl –xb” to view system logs

Enter your root Password twice to access the command prompt then type

shell

then

fsck /dev/mapper/log_vg-log

And answer Y to all the questions.

Reboot the VM.

And you are done.  I was able to log back in successfully after completing this procedure on all 3 VMs.

Note Order of completion should be:

1. PSC01
2. PSC02
3. VCSA
