Wei Zhou created CLOUDSTACK-1211:
------------------------------------
Summary: Network operations are Blocked for the Read-only file
system of Virtual Router
Key: CLOUDSTACK-1211
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-1211
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Affects Versions: 4.0.0
Reporter: Wei Zhou
Sometimes the virtual router VM has read-only file system for some reasons,
such as the Abnormal shutdown of the Host. This is not that we expected, but
really happens.
When this happens, the network operations will receive error messages and fail.
But indeed it is not. For example,
(1) Acquire IP. always in "Allocating" state.
(2) EnableStaticNat, the result is success(it is incorrect).
(3) DisableStaticNat. This is correct.
(4) Add Firewalls. always in "Adding" state.
Furthermore, The AgentManager report statistics every 60 minutes(normally it
should be router.stats.interval=5 minutes).
The agent.log show this after restart cloud-mnagement:

To reproduce
(1) log in the virtual router from console, or ssh from host.
(2) to generate errors, use "chattr =i -R /tmp"
(3) to remove errors, use "chattr -i -R /tmp"
