[one-users] Automatic recover from hardware failure

[Anandharaj Subramaniam]

Hi,

I experience this issue with my production environment. The issue was OpenNebula network setting was reset (network down few minutes) therefore ONE think that all the node is offline / error. As we set “redeploy” when host is in error, ONE initiate the redeployment. The moment ONE’s network is up, cause intermittent network issue and read-only mode on the VMs.

So, hope this will be addressed in the new solution as well.

I hope this particular feature is coming soon, as this is a standard ‘cloud’ feature for High Availability, and automatic failover.

The delete-recreate action will create a new VM from the original
template. This means that the VM will have a new ID, IP, and clean
disks.
We are working on a new mechanism for hosts with shared storage, to
"migrate" the failed VM to a new host keeping the current IPs, disk
state, etc.

Is there an ETA on this new mechanism? I just ran into the same problem today in my test setup.

I can't say when it will be ready. It's not a patch that you can apply, the changes are made in the core and the scheduler, so you will need to wait for the next OpenNebula release.

Regards.
