Network "restart required - yes"
Hi all,
does anyone know it means when on the Network tab (this is VPC network) it
says "Restart Required - yes" ?
(the VR is using latest, up-to-date template just FYI).
Thanks,

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....

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....

I'm fairly sure restart with clean up should destroy and recreate both simple VRs and VPCs
From watching the cloud.log when using restart (without cleanup) against a VPC - it didn't seem to do anything.

I have checked this before, but I do not know it by heart now.
If I had to guess, I would that say restart network will reboot the VR.
Restart network with cleanup (not the VPC) will remove and add
configurations applied in the VR after the reboot.
Restart network with cleanup (in the VPC) will destroy and recreate the VR.

Hi Rafael,
thanks a lot for digging into code - I undestand possible situations now -
thx.
Btw, do you know what actually REALLY happens when you restart Network
(part of VPC), not the whole VPC - since I was not clear if this does
anything (and it takes 1-3 seconds only...)
thx again

That means, something wrong happened either in "rollingRestartVpc" or
"startVpc" methods. Therefore, all of the affected networks should present
log entries such as " Failed to start vpc as a part of VPC ...." or "
Failed to execute a rolling restart as a part of VPC "

Without digging into the code, I believe that the VR reports the version and it's matched against the min version. i'm not sure what happens if the version is not reported at all.
Is this recent and have you updated the system QCOW2 or systemvm.iso recently? And if so, did you rebuild the rpms, or manually place the image or iso?
- Si

Minimum template version ss 4.6.0 (we run acs 4.8.x)

Andrija,
Is this isolated to that particular VPC, or is this across the entire zone? What's the minreq.sysvmtemplate.version global set to?
- Si
