Hello, We have an installation with 2 filers on CentOS 7.2 with the hosted engine appliance. We use iscsi for our backend storage. We have some issues We had to dedicate an entire dedicated storage domain for the sole use of the Hosted Engine appliance. Is this required ?

Or can the Hosted Engine appliance co-exist on another storage domain with VMs ? I have not been able to migrate the Hosted Engine VM to other storage. Because of this limitation and to be efficient with our storage use, we asked our storage admin to make a small iscsi LUN 20GB for the storage domain for the appliance. However, we are constantly getting errors regarding low disk space for this domain even though it has only the 10GB appliance.

Could this size problem be related to my problems with importing VMWare VMs into our larger (Multi TB) storage using the Import tool in 3.6. Thank You _______________________________________________ Users mailing list Users(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Hi Simone, I'm facing an weird behavior with my dedicated iSCSI Hosted Engine Storage Domain (this LUN has 50GB in size, which is more than enough for the engine storage domain). The engine vm itself is using 2.8G as you can see below, but the storage domain is consuming 49G. I don't have templates or snapshots...(Sreen Shots attached) Do you know whats happening? and I'm receiving Critical, Low disk space messages which are non sense.
