Hi Mathew,

Wow, thank you very much for the quick response!

I've gone ahead and tried to do what you've suggested, but I'm a bit confused as to how the storage is going to work...

If I add the storage domain on the Local datacenter, then I can only choose local_storage and then when I try add this storage as NFS, ovirt says the storage domain isn't empty (which it isn't) so I'm confused as to how both hosts will work together on the same storage domain?

All I'm wanting to achieve is a two host cluster with NFS storage from one host, is it not over complicating things using the AllinOne installation?

All-in-one is using local storage, not shared storage. So you can't use the local unshared data domain for a second host.

You may want to move the host to maintenace, detach it from local_datacenter, attach it to default, create a nfs data domain and attach it to default and then add a second host there.

Or you may explore Hosted Engine solution.

Thank you, and apologies if I've perhaps misunderstood.

Regards.

Neil Wilson.

Since the storage is NFS it really doesn’t matter where it is located at so long as all hosts can talk to it via ip

Basically if you have the nfs storage locally or otherwise you can simply add another host to the datacenter and then you should be able to use the storage across the new host

Keep in mind you will need to make it so the external host is able to access the nfs share

Hi guys,

Please excuse this if it sounds like a dumb question, it's my first time doing an All-in-one" oVirt installation

I've installed the All-in-one on one physical machine, and configured this as a host in the cluster, and my intention was to use local NFS storage as the primary storage domain for the VM's, but then add a second host to the cluster which would access this NFS primary storage domain on the original "All-in-one" installation...
After doing the install when I log in I see that when you do an "All-in-one" install you end up with a "local_cluster" as well as a "Default" cluster and you can't add another host to the "local_cluster", so it appears I'll need to add the second host to the "Default" which I'm assuming means I won't be able to share the primary NFS storage between the two clusters and I won't get live migration between my two physical hosts across the clusters?

Could anyone confirm if my assumptions are correct please?

Thank you!

Regards.

Neil Wilson.
