[ovirt-users] Re: New to oVirt - HE and Metric Store Question
I can't recall the exact issue that was reported in the mailing list, but I remember
that the user had to power off the engine and the VMs... the Devs can clearly indicate the
risks of running the HostedEngine with other VMs on the same storage domain.
Based on Red Hat's RHV documentation the following warning is clearly indicating some
of the reasons:
Creating additional data storage domains in the same data center as the self-hosted engine
storage domain is highly recommended. If you deploy the self-hosted engine in a data
center with only one active data storage domain, and that storage domain is corrupted, you
will not be able to add new storage domains or remove the corrupted storage domain; you
will have to redeploy the self-hosted engine.
Another one from Red Hat's Self-Hosted Engine Recommendations:

What kind of situation is that ? If so, how can I migrate my hosted engine into another
storage domain ?

1. Right now we are using one SAN with 4 LUN (each mapped into 1
>specific volume) and configure the storage domain for each LUn (1 LUN = 1 >Storage
Domain). Is this configuration are good ? One more, about Hosted >Engine, when we setup
the cluster, it provision one storage domain, but >the storage domain is not exlusively
used by Hosted Engine, we use it too >for other VM. Are this OK or it have a side
impact ?
Avoid using HostedEngine's storage domain for other VMs.You might get into situation
that you want to avoid.
