why at host level and not via api or ovirt-cli?
That is correct, you can also see the size and the fields through the
API or ovirt-cli
(see
http://documentation-devel.engineering.redhat.com/site/documentation/en-U...)
though, you can not see the true size in the floating disk, IINM you can
see it under the VM snapshots disks in the API.
I think that since I already saw this question before, maybe its worth
to open an RFE on that issueת perhaps changing the column name to
full_disk_size ןמ איק GUI or adding a column of actual size in the disks
main tab?
