Improving code related to the Agent properties by paulazomig · Pull Request #6348 · apache/cloudstack

paulazomig · 2022-05-02T19:29:47Z

Description

The classes AgentProperties and AgentPropertiesFileHandler were previously created to map the existing properties of the agent.properties file to facilitate their use; however, only a few properties were mapped at the time.

This PR aims to build on those changes. All of the properties of the agent.properties file were mapped in the AgentProperties class.
While executing the mapping, I found some properties that were used in the code, but were not documented in the "agent.properties" file. These properties were also documented, and registered accordingly in the properties file.

The way the properties were accessed in the code was changed, and now the values are obtained through the AgentPropertiesFileHandler class. Also, Unit Tests were added and modified according to necessity.

How Has This Been Tested?

This was manually tested in a local lab, by altering properties and performing main actions: creating and deleting VMs, creating new Volumes and snapshots, etc.

@GutoVeronezi the ssvm still won't come up with this message:

@DaanHoogland, that message is printed when the secondary storage is not mounted in the SSVM; then, the script ssvm-check.sh tries to ping the "NFS server" to validate the connectivity. For some reason it infers that the NFS server is the seventeenth element of file /var/cache/cloud/cmdline; however, the index of the elements will vary according to some configurations. I created PR #6900 to handle this situation, could you take a loot at it?

Although the script problem, the main situation is that the secondary storage is not being mounted in the SSVM. Would it be possible for you to share the SSVM logs? This way we would have a better understanding of why the storage is not being mounted.

I am building an environment for this again. I take it it isn´t happening in your environment?

I think I need to find time to enable debug logging and retry, @GutoVeronezi . I see nothing of interest there.

@DaanHoogland

Yes, perhaps due to divergent configurations or something I am missing. I will review the code and analyze the logs you shared (thanks, though). Maybe the message Tue 15 Nov 2022 08:16:09 AM UTC Incompleted parameters STORAGE_IP:, STORAGE_NETMASK:, STORAGE_CIDR:. Cannot setup storage network can lead to somewhere.

GutoVeronezi · 2022-12-15T17:53:21Z

@DaanHoogland I think I found out what was happening. When patching the system VMs, the file systemvm/agent/conf/agent.properties is copied to them. This file contains two hardcoded properties:

instance=ConsoleProxy
resource=com.cloud.agent.resource.consoleproxy.ConsoleProxyResource

As AgentShell was changed to use the configurations from agent.properties instead of the parameters passed in the command line, the SSVM was being started with the hardcoded property resource (com.cloud.agent.resource.consoleproxy.ConsoleProxyResource) and trying to start as a CPVM.

I made a change to remove those hardcoded properties when the system VM is a SSVM and to copy the content of file /var/cache/cloud/cmdline to agent.properties during the bootstrap, making AgentShell use the proper properties.

Following there is the content of the agent.properties of both system VMs after the change:

For SSVM

For CPVM

@DaanHoogland, can we run the tests again?
