I am trying to format attached volume of an instances it is throwing an error below.

“changed”: false,  
“failed”: true,  
“invocation”: {  
“module\_args”: {  
“dev”: “/dev/xvdf”,  
“force”: false,  
“fstype”: “ext4”,  
“opts”: “-t”,  
“resizefs”: false  
},  
“module\_name”: “filesystem”  
},  
“msg”: “Device /dev/xvdf not found.”  
}

when type lsblk command instance displays volume.

Similary when i am trying to use apt\_key module it is not changing anything on new instances simple changed flag is false.

Thanks in advance
