Hi Alex, What that you suggest is pretty similar to have two different Data Center. One with host HV1 and storage domain 1. The other with storage_domain_2 and HV2 host. This might work, and your two hosts will be SPM, one for DC1 and the other for DC2 I'm not sure that I follow your suggestion ab

I was just thinking - maybe adding a setting to storage domains who's the "master" for that specific storage domain would get around this ? e.g. storage_domain_1 => master = HV1, storage_domain_2 => master = HV2, etc. etc. What do you think ? Alex On 18 January 2013 09:34, Alex Leonhardt wro

Hmmm, but if I put the SPM host into Maint mode, then all the VMs would either be migrated or (in my case, all set to manual) not available during that time, correct ? Would changing the SPM priority in the host config have the desired effect w/o putting the host into Maint mode ? Or can I only do

Hiya, Yes i can choose the storage domain, but I cannot force the host that is to be used for creating it. Even with 1Gbit network, creating a 80GB disk / 40 GB disk is still significantly longer process than actually required when doing a "dd" of /dev/null over the network. Is it possible t

Hi Alex, The storage domains are part of the Data Center, and should not be related to clusters. Clusters are used for migrating VMs, which are the qemu processes, between hosts. Disks are created on the storage domains regardless to clusters. The host which write the data in the storage domain to

Hi, I see a strange behaviour - Setup: 1 ovirtmgmt / ovirt-engine hsot 2 ovirt nodes / HVs 2 storage domains in same cluster & DC HV1 => storage domain 1 (master) HV2 => storage domain 2 Issue: When I create a host with say ~40GB disk to be on HV2/storage_domain_2, it does that via HV1 ? Wh
