How to clean the metadata of redeployed Hosts in a Hosted Engine setup

Solution Verified - Updated -

Environment

  • Red Hat Virtualization 3.x, 4.x

Issue

I have re-deployed a Host without cleaning first the metadata and now i can see multiple entries for this Host in:

# hosted-engine --vm-status

Resolution

1. Stop the High Availability Agent on the Host, which was re-deployed without cleaning first the metadata:

     # systemctl stop ovirt-ha-agent

2. Clean its metadata

     # hosted-engine --clean-metadata --host-id=$old_ID --force-clean

3. Start again the ha-agent

     # systemctl start ovirt-ha-agent

4. Verify on this and the rest of hosts of the Hosted Engine environment with:

       # hosted-engine --vm-status

5. Repeat for every Host with the same "issue".

For example, you have Host 5 with two IDs in "hosted-engine --vm-status" output

Hostname : Host05
Host ID : 9

Hostname : Host05
Host ID : 8

and the current ID is 9. You can verify it on Host05 at /etc/ovirt-hosted-engine/hosted-engine.conf
...
host_id=9
...

Follow the above procedure and in the second step run:

# hosted-engine --clean-metadata --host-id=8 --force-clean
