Hello, thank you for helping me.

On the storage domain size:

Alias: host1

Disk: 1

Template: Blank

Virtual Size: 30 GB

Actual Size: 13 GB

Creation Date: Jan 29,2018 11:22:54 AM

On the server size:

# df -h

Disk Flags:

Disk /dev/mapper/vg01-swap: 2147MB

Disk Flags:

Disk /dev/mapper/vg01-root: 10.7GB

Disk Flags:

It still not the same. 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?

Terry

Hi

For 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 ^Disk
Disk /dev/sda: 26.8GB
Disk Flags:
Disk /dev/mapper/rootvg-lv_tmp: 2147MB
Disk Flags:
Disk /dev/mapper/rootvg-lv_home: 210MB
Disk Flags:
Disk /dev/mapper/rootvg-lv_swap: 2147MB
Disk Flags:
Disk /dev/mapper/rootvg-lv_root: 21.8GB

So I see that VM has 26.8GB big disk.

Hello~
i type this command on the running vm, not the hypervisor ( ovirt node).
