Did you manually tried to avoid the issue of a single entry point for the gluster FS volume using host01.ovirt.forest.go.th:_hosted__engine and host02.ovirt.forest.go.th:_hosted__engine there? This could cause a lot of confusion since the code could not detect that the storage domain is the same and you can end with it mounted twice into different locations and a lot of issues. The correct solution of that issue was this one: https://bugzilla.redhat.com/show_bug.cgi?id=1298693#c20 Now, to have it fixed on your env you have to hack a bit. First step, you have to edit /etc/ovirt-hosted-engine/hosted-engine.conf on all your hosted-engine hosts to ensure that the storage field always point to the same entry point (host01 for instance) Then on each host you can add something like: mnt_options=backupvolfile-server=host02.ovirt.forest.go.th:host03.ovirt.forest.go.th,fetch-attempts=2,log-level=WARNING,log-file=/var/log/engine_domain.log Then check the representation of your storage connection in the table storage_server_connections of the engine DB and make sure that connection refers to the entry point you used in hosted-engine.conf on all your hosts, you have lastly to set the value of mount_options also here. Please tune also the value of network.ping-timeout for your glusterFS volume to avoid this: https://bugzilla.redhat.com/show_bug.cgi?id=1319657#c17
