[ovirt-users] virtual machine actual size is not right

[Terry hey]

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
Filesystem               Size  Used Avail Use% Mounted on
/dev/mapper/vg01-root     10G  7.2G  2.9G  72% /
devtmpfs                 1.9G     0  1.9G   0% /dev
tmpfs                    1.9G  4.0K  1.9G   1% /dev/shm
tmpfs                    1.9G   17M  1.9G   1% /run

tmpfs                    379M     0  379M   0% /run/user/0

# parted -l /dev/[sv]d[a-z] | grep ^Disk
Disk /dev/sda: 32.2GB
Disk Flags:
Disk /dev/mapper/vg01-var: 16.1GB
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?

Regards,
Terry
