This is expected. The question here is why the block job seems not to end. Is there any high I/O on that specific disk during the migration? Could this be similar to BZ 1376580 also reported by you? 4.0.6 has been the last oVirt 4.0 release, please re-target this bug. Closing as there's no new info for nearly 2 months, feel free to reopen if new data will arrive |
