How do i use local storage of hosts with ovirt?

I plan NOT to use shared storage or network storage and will be using local storage of hosts to provision storage for VMs How do i do this? For example in this screenshot, no way to configure local storage Thanks

This is for a private cloud and no thanks..i am okay with my local storage..have the local storage in RAID 1 and have a dedicated backup server with bacula doing continuous backup. Having a network storage complicates things, and i dont want it..at least not now...maybe in 3 years i may want it but not now for what i am doing. So anyone willing to help with how to setup hosts to use local storage? Thanks On Wed, May 28, 2014 at 9:11 PM, Paul Robert Marino <prmarino1@gmail.com>wrote:

As I already wrote to you you have to put the host into maintenance mode in order to be able to configure local storage. Didn't this work? Regards, René
Thanks

This is why i like Ganeti because they are the only one that understand there is a niche and support for clusters using local storage of hosts. I mean not everyone wants a Shared/network storage for crying out loud. On Wed, May 28, 2014 at 9:11 PM, Paul Robert Marino <prmarino1@gmail.com>wrote:

For sure an All-In-One installation lets you configure a local storage domain: http://www.ovirt.org/Feature/AllInOne I have one setup like this where I definied more local storage domains (aka more mount points pointing to different disks with different speeds...) I don't know if this can match your needs I don't remember if you can configure local storage domain for a non-allinone setup. If not, I think it would be interesting to offer it as an enahncement for future releases. A possible workflow could be: offer chance to add local storage only if the cluster is composed by only one node and in that case show a big warning that adding a local storage would prevent adding other nodes to this cluster therafter. If trying then to add another node, show a message that it is not possible as it has a local storage domain attached Gianluca

Yes you can. Put the/a host in maintenance, then create local storage and move the host to the datacenter/cluster that has been generated and bring it up. You can't have two hosts using the same local storage but that is by design :-) No hosted engine too. Joop
