Flush sync failed during upgrade process

[atom (Ammo)]

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
