-------------------------------------
Summary: [Multiple_IP_Ranges] Failure in deleting guest IP range
should mark nic_ip_alias state to Revoked
Key: CLOUDSTACK-2641
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-2641
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Management Server
Affects Versions: 4.2.0
Environment: Latest build from master branch:
CloudStack-non-OSS-MASTER-394-rhel6.3.tar.gz
Reporter: Sanjeev N
Priority: Critical
Fix For: 4.2.0
Failure in deleting guest IP range should mark ip alias state in nic_ip_alias
table to Revoked
Steps to Reproduce:
=================
1.Bring up CS in basic zone with xenserver 6.1
2.Exhaust all the guest IP ranges from the primary IP range added during zone
creation
3.Add another guest IP range in new CIDR
4.Deploy guest vm
5.Set expunge interval to a small value say 60 secs, and restart management
server
6.Destroy the guest vm deployed at step4
7.After vm expunge, delete the guest IP range added at step3
Expected Result:
=============
In case of successful deletion of the guest IP range , ip alias created on VR
should be deleted and the entry from nic_ip_alias table should be removed.
Actual Result:
============
Due to bug CLOUDSTACK-2621, IP range deletion failed and alias IP address
remained in allocated state in user_ip_address table but ip alias was removed
from the backend(from the VR).
nic ip alias state shows active in the DB.
Impact:
======
Since the deletion failed, if the user wants to use the ip range and tries to
deploy vm using this guest IP range, guest vms does not get the IP address
since VR does not have ip alias to server dhcp request in this guest range.
CS does not try to recreate ip alias on VR since nic_ip_alias table shows the
state as active.
