        Hello!
         
        I have problem with slow requests on kernel 4.4.0-45 , rolled back all  nodes to 4.4.0-42
         
        Ubuntu
            16.04.1 LTS (Xenial Xerus)
        ceph
            version 10.2.3 (ecc23778eb545d8dd55e2e4735b53cc93f92e65b)
         
      
    Can you describe your problem with slow requests? Is it just like in
    the other thread " ceph cluster having blocke requests
    very frequently"?

    
    I have the same problem as him, but with 10.2.3 and kernel
    3.13.0-96-generic from Ubuntu 14.04. Would you suggest trying
    4.4.0-42, or a vanilla 4.4?

    
    (see my message in that thread for details.)
