Hi,

i am currently trying to upgrade my elasticsearch instance and tried to do a flush synced.  
I am getting this response the whole time:

> ".monitoring-es-6-2018.02.20" : {  
> "total" : 2,  
> "successful" : 0,  
> "failed" : 1,  
> "failures" : [  
> {  
> "shard" : 0,  
> "reason" : "pending operations",  
> "routing" : {  
> "state" : "STARTED",  
> "primary" : true,  
> "node" : "--eGugLCRjCZbQO-Fq0ICQ",  
> "relocating\_node" : null,  
> "shard" : 0,  
> "index" : ".monitoring-es-6-2018.02.20",  
> "allocation\_id" : {  
> "id" : "CFStYCP-Ru6e1NCqoJ8DCQ"  
> }  
> }  
> }  
> ]  
> },

I am waiting for half an hour now and this is not going to be solved i think.  
Can i proceed the upgrading process anyway?

Regards,  
Ahmet
