    IO delay randomly appearing, proxmox 5.1-36

    No problem with the long answer (as if mine wasn't). Just if you want to know more about VM, currently there is : 6 linux with each 1GB ram, 1socket/1core and 5GB to 250GB disk (most of them running at less than 10% CPU and 600MB of ram used) 1 windows 2016 server with 6GB ram, 4sockets/2cores...

    I don't remember using ZFS (didn't install promox 5 ZFS at least), so I don't think it would impact my server / VM in any way (why would that happen now [this week + randomly] and not everyday ?).
