VM state is "running (io-error)"

[greg]

Greetings

One of my VMs is not responsive and stated as "running (io-error)" in the GUI.
The "console" in the GUI is blank.


How can I understand and investiguate the problem?

Thanks in advance

Did you look in SYSLOG, maybe there is a Problem with a Disk?

Thanks for your answer.
Nothing in syslog, I did a zfs scrub and smart long test, nothing...
