Viewed 420 times

Summary

An administrator may experience after a Failover or Move that a Recovery VM running RHEL/CentOS 7 is booting into Emergency Mode rather than finding the OS and awaiting for login.

Symptoms

CentOS 7 / Redhat 7 recovery VM boots into Emergency Mode/Shell and thus login is not possible, rendring the VM as unusable.

Solution

To resolve the issue, perform the below Steps on the affected recovery VM:

  1. Restart recovery VM and choose rescue mode in Grub.

  2. Run command dracut -f and reboot the VM.

Note: If the VM has multiple initramfs, run dracut -fv --regenerate-all alternatively.
