Description of problem: following bug 883939: At the moment vdsm needs to pause the VM for a short moment during the volume refresh (after an extend). In certain cases (or if the refresh takes few seconds) it might be also reported to the engine. Version-Release number of selected component (if applicable): vdsm-4.9.6-44.2.el6_3.x86_64 How reproducible: 100% Steps to Reproduce: 1. Run several thin provision vm's 2. move the vm's disks to a second storage 3. Actual results: vm's status changes to pause -> up when we refresh the disk Expected results: vm status should not be changed Additional info: logs can be found in bug 873145

There is an old poc upstream for this: [poc] vm: do not pause during refreshVolume Signed-off-by: Federico Simoncelli <fsimonce> Change-Id: I896993c00b94c3255ad2007486e0589bf10b3a98 http://gerrit.ovirt.org/#/c/8382 If we decide to go this way we need to consider that the patch affects many flows and it should be tested extensively. Best idea is probably to introduce that at the beginning of a cycle of development (rather than at the end). Bug is not frequent anyway (I haven't heard of it since a while). It is probably triggered only in special cases when the storage is under heavy load.
Fede, update on verification of patch? it would be better to push this in asap to get the most testing we can...
The patch was merged in master. Waiting for inclusion in 3.4.
verified - followed the steps to reproduce
