Moving a POSIX storage domain to be a Local Storage
Hi, In the initial setup I wasn't aware of the option to assign a local disk as Local Storage and we have added it as a POSIX complaint Storage Domain, now that we want to add a new KVM host, it needs to attach the storage domain to the new host, which it obviously can't. My question is, how do I remove the Storage domain and add it back as a Local storage without harming the VMs that are already on the system (obviously some downtime will be needed) I guess that I can add another Storage Domain and start moving them to a "temp location" and then back, question is if there is another quicker way.

Can you please elaborate a bit more on the use case? you can't mix local storage domains with 'shared' storage domains currently, nor have multiple hosts with local storage domain in the same cluster (in the works, but not yet).
Any knowledge as of when this "on the works" will be done? In addition, we will want to migrate the VMs later on to be on the local disks, which setup would be currently better? Using NFS with single datacenter, each kvm host will export his local drive as NFS and the VMS will be binded to start on the specific host or have multiple datacenters, each with a single KVM host? thanks in advance On Thu, Aug 28, 2014 at 2:41 AM, Itamar Heim <iheim@redhat.com> wrote:

to mix local storage and shared storage in same cluster - i doubt will make it for 3.6 (which will focus on enabling this flow by removing the SPM role). so ~12 months.
In addition, we will want to migrate the VMs later on to be on the local disks, which setup would be currently better? Using NFS with single datacenter, each kvm host will export his local drive as NFS and the VMS will be binded to start on the specific host or have multiple datacenters, each with a single KVM host?
using NFS exported by the different hosts means if that host is down, the VMs won't be able to run on other hosts. if you want to use local storage in a cluster of hosts, usually gluster is the solution?
thanks in advance
