It looks, that I have 2 shards unassigned, because two other shards were stuck in "RELOCATING" state.
<https://lh5.googleusercontent.com/-TD84Uz8lg5Q/VGtGVXVIFVI/AAAAAAAAAK4/ITudefzX1qQ/s1600/ES_RELOCATING.png> And I think I have them migrating here and there, and while they are trying to find the new home for themselves, it's not possible to allocate those 2 shards. I've tried to close the index and then open - when the index was closed - all the remaining shards were allocated successfully, after I've opened it again - no shards remain unassigned. So the current question is - why some shards are relocating constantly.
