[ovirt-users] Multi-node cluster with local storage

[Pavel Gashev]

Christophe,

Where is the engine running? Did you use one of NFSs for hosted-engine?

Thank you

Hi,

We have all nodes like you (5 currently), and have them setup as NFS instead of local storage.

You have slight overhead because it's NFS, but not so much, and it allows you to migrate VMs and disks, even if it's a manual disk, eg no HA will be possible.

So yeah, to me, it's a good option given your setup.

Best,
