--------------------------------------------
Summary: rVPC ACL doesn't recover after cleaning up through the
NetworkGarbageCollector
Key: CLOUDSTACK-9189
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9189
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Virtual Router
Affects Versions: 4.6.0, 4.7.0, 4.6.1, 4.6.2
Reporter: Wilder Rodrigues
Assignee: Wilder Rodrigues
Priority: Critical
Fix For: 4.7.1
In order to reproduce this bug quicker is better to change the
network.gc.interval and gc.wait from 600 seconds to 10 seconds via Global
Settings and restart your management server.
- deploy a rVPC
- deploy VM in it
- make port forwarding (2nd ip, firewall and such)
- confirm it works
- stop the vm
- after some time (20 seconds * 3 - approximately) the network garbage
collector will come and tear down the network since there are no more VMs
- all the nics will be fine and the guest nic will be gone. The routers should
be on BACKUP/BACKUP
- then start the vm again
- the nics get plugged again and keepalived will decide on a new master.
- try to SSH into the VM via the public IP. It will fail
The only way to get it working afain is:
- Replace the network ACL - for example, default allow all
- Try to SSH again and it works fine
- Replace back to your original ACL
- Try to SSH again and it works fine
