Also, do you know the upper limitation for thin provision?For example, if i allocated 30 GB to the hosts, what is the upper limitation that the host can use?Regards,Terry2018-03-23 18:45 GMT+08:00 Pavol Brilla <pbrilla@redhat.com>:HiFor such big difference between size outside of VM and inside, it looks more that disk is not fully partioned.df is providing you information only about mounted filesystems.Could you try to run inside VM should match all local disks, and you should see size of disk :# parted -l /dev/[sv]d[a-z] | grep ^Disk( Output of 1 of my VMs ):# parted -l /dev/[sv]d[a-z] | grep ^DiskDisk /dev/sda: 26.8GBDisk Flags:Disk /dev/mapper/rootvg-lv_tmp: 2147MBDisk Flags:Disk /dev/mapper/rootvg-lv_home: 210MBDisk Flags:Disk /dev/mapper/rootvg-lv_swap: 2147MBDisk Flags:Disk /dev/mapper/rootvg-lv_root: 21.8GBSo I see that VM has 26.8GB big disk.On Thu, Mar 22, 2018 at 5:56 PM, Terry hey <recreationh@gmail.com> wrote:Hello~i type this command on the running vm, not the hypervisor ( ovirt node).--
