Hello Greg,
     You can help me?

Thanks.

Hi Marcelo,

I see in your engine log that one of the images can't be found when a merge is attempted:

  VDSErrorException: Failed to MergeVDS, error = Drive image file could
  not be found, code = 13

There were some recent fixes to Live Merge that help is progress beyond this particular error, see [1] for details on that. The fix is in 3.6.6.

It might be helpful to check the vdsm log to see what happened on the host when the first merge on that snapshot was attempted. It should be in the Host04 log around time 2016-05-11 19:33:43.

Thanks,
Greg

        Hi Marcelo,

        Can you try to remove the snapshot again and attach the engine log
        if it fails?

        Thanks,
        Greg
