Hi folks, I have a question about master domain when I'm using hosted engine deployment. At the beginning I've made deployment on NUC (small home installation) with hosted engine on the nfs share from NUC host. I've configured FS gluster on the same machine and used it for master domain and iso domain. Lets say All-in-ONE. After reboot happened something strange. Log says that master domain is not available and has to become on the hosted_storage. This is not ok in my opinion. I know that behavior because master doamin is not available, has been migrated to other shareable (in this case hosted_domain is nfs ). Do you thing, that should be locked in this particular case means when available is only hosted_storage? Right now it is not possible to change this situation because hosted engine resides on the hosted_storage. I Can't migrate it.

In the past we had a bug that let you remove the last regular storage domain and it the case the hosted-engine would become the master storage domain and as you pointed out that was an issue. https://bugzilla.redhat.com/show_bug.cgi?id=1298697 Now it should be fixed. If it just happened again just because you gluster regular storage domain wasn't available is not really fixed. Adding Roy here. Dariusz, which release are you using?
