hi Everyone,

I upgraded my last node but due to some issue 36 shards left unassigned. and its not getting assigned because of below issue:  
"can\_allocate" : "no\_valid\_shard\_copy",  
"allocate\_explanation" : "cannot allocate because a previous copy of the primary shard existed but can no longer be found on the nodes in the cluster",

Please help me asap . Now only master node is left to upgrade
