[ovirt-users] Cloudspin Storage changes

Mon Feb 9 11:12:47 EST 2015

I guess I should explain why I not using gluster at this time for storage. I was made aware that you should not run both gluster and virt on the same node, and I just don't have the hardware to support that. 

Gluster is a fine product, and when I get enough hardware to support building a gluster cluster, I will add it back into cloudspin. 

The sole reason I have to put gluster on the back burner is because I am the only one who pays for the power to keep this gear on, and I need to be able to keep as few servers on as possible to suite the demand. 

Thanks, 

Donny D

Well, I have everything fixed, and by fixed I mean all the users vm's won't import.  

My gluster experiment is over, and I have moved the storage to an actual storage device. Hopefully everyone isn't too mad

Hi Donald,

Can you please elaborate more on the process, I'm not sure I understood the scenario clearly.

Regards,
Maor

Is engine setup was on gluster, or the Storage domains which was used for the VM's disks?

How they were imported?
