It looks like you have a problem setting, the ceph storage as SDM. You may need to have a regular storage domain first before adding the ceph one, but it's really hard to tell like this. You can look at sp.py#startSpm On Wed, Oct 24, 2018 at 9:29 AM Tianyuan Wang <tywang0113@gmail.com> wrote:
hi all, We are developing for supporting ceph as a new storage domain type. It went well when creating and using. But we cannot add a new host to the engine when there is already a ceph-StorageDomain. The engine reports "VDSM node1 command ConnectStoragePoolVDS failed: Cannot find master domain" and set the node to "Non Operational" status. The vdsm log reports error like this:

After tracing back, I found that there is no local file path under /rhev/data-center/mnt for the storage domain, so it cannot find storage domain when ConnectStoargeSever runs. It only happens when adding a new host to engine and there is already a ceph-StroageDomain in ovirt. So how does the host synchronized the existing storage domains? And what can I do to fix this?
Thanks in advance!
