Please add the logs above the log you posted, with the string "Run and
protect, connectStorageServer"

This log contains the arguments received from engine, revealing what
is going on.

-t glusterfs is missing here

Could it related to the auto-import feature?

Did it correctly recognized the hosted-engine storage domain as a gluster one?

Adding Roy here.

This line can be generated only by the GlusterfFSConnection, used when
connecting
to gluster storage domain, but this connection type ads the "glustefs" type.

Same storage domains? Maybe you mean same bricks?

You cannot use the same storage domain from different DC. You can
create new gluster volume
using the same bricks.
