Issue/Introduction

We are trying to enable snapshot option on the gateway 9.4 CENTOS server running in azure platform. 

After the respective log analysis and looking at the VM details we have found the following:

 

 

1. The log observed indicates that there is a problem with the Agent extension handlers:

2020-12-05T05:42:25.088870Z ERROR ExtHandler ExtHandler Event: name=WALinuxAgent, op=ExtensionProcessing, message=Exception processing extension handlers: ….

2020-12-05T05:42:31.200550Z WARNING ExtHandler ExtHandler Exception processing extension handlers: 0

 

2. The error appeared after the Backup Extension was able to be executed by the Linux Agent when removing the noexec parameter from /var

 

Environment

Release : 9.4

Component : API GATEWAY

Resolution

We were able to resolve this by doing the following actions:

1. open /etc/fstab, for /var entry replace noexec with exec.

2. Restart the gateway server

3. Restart the waagent - service waagent restart

4. Check the status of waagent - service waagent status.
