[ovirt-users] The Hosted Engine Storage Domain doesn't exist. It should be imported into the setup.

[Paolo Margara]

Hi list,

I'm working on a system running on oVirt 3.6 and the Engine is reporting
the warning "The Hosted Engine Storage Domain doesn't exist. It should
be imported into the setup." repeatedly in the Events tab into the Admin
Portal.

I've read into the list that Hosted Engine Storage Domain should be
imported automatically into the setup during the upgrade to 3.6
(original setup was on 3.5), but this not happened while the
HostedEngine is correctly visible into the VM tab after the upgrade.

The Hosted Engine Storage Domain is on a dedicated gluster volume but
considering that, if I remember correctly, oVirt 3.5 at that time did
not support gluster as a backend for the HostedEngine at that time I had
installed the engine using gluster's NFS server using
'localhost:/hosted-engine' as a mount point.

Currently on every nodes I can read into the log of the
ovirt-hosted-engine-ha agent the following lines:

...and the following lines into the logfile engine.log inside the Hosted
Engine:

How can I safely import the Hosted Engine Storage Domain into my setup?
In this situation is safe to upgrade to oVirt 4.0?
