Without changing anything on my Nexenta 3.1.1 ent appliance, I cannot login to nmc or the web gui any more. I can login with user admin but not with root. When I try to login as root I get after waiting 5 minutes: SYSTEM NOTICE

 Failed to initialize NMC:
 no introspection data available for method 'get_props' in object '/Root/Appliance', and object is not cast to any interface

 Suggested possible recovery actions:
    - Reboot into a known working system checkpoint
    - Run 'svcadm clear nms'; then try to re-login
 Suggested troubleshooting actions:
    - Run 'svcs -vx' and collect output for further analysis
    - Run 'dmesg' and look for error messages
    - View "/var/log/nms.log" for error messages
    - View "/var/svc/log/application-nms:default.log" for error messages

Entering UNIX shell. Type 'exit' to go back to NMC login...

Here are some screenshots:

No idea what might have caused it.

Any help would be appreciated.
