Re: Network "restart required - yes"


Hi Andrija,


Since you're running an older ACS 4.8.x version, the rolling restart VPC code does not apply for you. Performing restart of a vpc network (tier, and when cleanup is not selected) will not restart the VPC VR but only re-apply the networking rules.


When due to a failed shutdown of network elements or failed restart attempt, the VPC fails to restart, the restart_required column in vpc table is marked as true. This is the relevant code wrt 4.8:

https://github.com/apache/cloudstack/blob/4.8/server/src/com/cloud/network/vpc/VpcManagerImpl.java#L1553


It's possible that the restart flag in API response and UI is not actually *necessary*, this is just a presentational issue for users to perform an action when any past action may have failed.

Well, not recent at all, and no issues so far.... update was done a few
months, and as I stated above, from DB I got all VRs reported to be running
4.6.0 version - I assume DB is populated dynamically as VR reports the
version to MGMT server....

Need to think...
