This can happen when using thin provisioned disks on block storage (iSCSI, FC). I then try to add a new iSCSI Data Storage Domain on this Data Center and I have selected to use the only host I have where the iSCSI target also resides, over a local device. It works using QCOW2 disk images directly on LVM volumes. However, the system only allows moving between same domain subtypes. Storage Domain will be added to the list of Domain and can be used as a storage for . oVirt manages virtual machines, storage and virtualized networks. Provision a cluster, add the Ubuntu host to Engine in the web admin GUI as usual. I moved all the data to another storage (except of OVF) After the recover of the storage, the administrator rebuild an array for the ovirt installation but the wwid changed from: I have one server. 7.

Discover targets via iSCSI links, which were previously configured. The big difference you will see between ovirt and vmware is that Ovirt uses lvm volumes on block storage (iscsi/fc) and disk files on file based storage (nfs) so you cannot easily storage migrate between block based and file based storage backends. General Variables. Test every combination of Edit Network, every boot protocol with combination of IPv6 or IPv4 addresses. Utilities; 18.

Attention: When you have a data center with only one active data storage domain and that domain gets corrupted, you are unable to add new data storage domains or remove the corrupted data storage domain. After rebooting a h Both systems have CentOS 7 installed and expose storage via iSCSI and NFS. Discover LUNs from the add storage domain menu in oVirt web UI, choose iSCSI domain type with machine's IP address, "login all" and "add" for choosing the used LUNs. oVirt extends volumes when QCOW2 is growing. When I repeat this setup with iSCSI disks, I have at least a running hosted_engine on the iSCSI lun. I assume this is due to the storage domain already having a storageId that is used within ovirt.
