Problem
When VMs experience underlying storage errors, it is possible to encounter VMs stop behaving normally such as the file systems become ready only and not responsive.
Especially for Linux-based servers, it is common for file systems to be configured to remount in read-only mode if errors are detected and the same behavior is expected even on a native Linux environment.
Symptoms
Below is some of common symptoms VMs could experience after being recovered from underlying storage problems.
· Blue Screens - Older version of Windows
· VM State is “powered on” but VMWare tool status shows “Not Running”
· Unable to login to OS even with correct credentials
· CPU Utilization pegs at 100%
Solution
If you are having any of these symptoms above, please try to Reset VM (not “Restart Guest”) from vCenter Client menu and see problems are resolved.
(Note: “Restart Guest” may not work as it requires VMware Tools up and running)
