set to false.
Key: CLOUDSTACK-4643
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-4643
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Management Server
Affects Versions: 4.2.1
Environment: Build from 4.2-forward
Reporter: Sangeetha Hariharan
Priority: Critical
Fix For: 4.2.1
When the master host is put in maitenance mode , another host in the pool is
set as master. This is with manage.xenserver.pool.master set to false.
Steps to reproduce the problem:
Advanced zone set up with 2 Xenserver hosts (6.0.2) in cluster.
I want to upgrade the Xenserver hosts to 6.2.
Followed these steps:
1. Edit the file /etc/cloudstack/management/environment.properties and add the
following :
manage.xenserver.pool.master=false
2. Restart management server.
3. Put the Master Host (H1) in maintenance mode.
This results in the all the Vms in this host to migrate to another host (H2).
It also results in making the other host (H2) in the cluster as the Master of
this pool.
4. Unmanage the cluster.
5. Try to upgrade the host (H1) that was put in maintenance mode.
Upgrade complains saying that the master host of the pool should be upgraded
before this host can be upgraded.
Step 3 which is putting Master Host (H1) to maintenance mode should not have
resulted in changing the master of the pool to another host.
