Actually it only happened with empty disk (thin provisioned) and sudden
high I/O during the initial phase of install of the OS; it didn't happened then during normal operaton (even with 600MB/s of throughput).

Hi Gianluca,
Is it happening to machines with preallocated disks or on machines with thin disks ?
Best Regards, Strahil Nikolov
thin provisioned. But as I have tro create many VMs with 120Gb of disk size of which probably only a part during time will be allocated, it would be unfeasible to make them all preallocated. I learned that thin is not good for block based storage domains and heavy I/O, but I would hope that it is not the same with file based storage domains... Thanks, Gianluca
