Description of problem: I've tried to add removable usb device to machine before accepting node and Console has add this device to "Raw capacity". Finally it hasn't use it for OSD. But I expect that Console should not use removable disk for counting "Raw capacity" in Cluster wizard at page "Select Hosts". Removable disks should be ignored. Version-Release number of selected component (if applicable): server: ceph-ansible-1.0.5-23.el7scon.noarch ceph-installer-1.0.12-3.el7scon.noarch rhscon-ceph-0.0.27-1.el7scon.x86_64 rhscon-core-0.0.28-1.el7scon.x86_64 rhscon-core-selinux-0.0.28-1.el7scon.noarch rhscon-ui-0.0.42-1.el7scon.noarch storage node: ceph-base-10.2.2-5.el7cp.x86_64 ceph-common-10.2.2-5.el7cp.x86_64 ceph-osd-10.2.2-5.el7cp.x86_64 ceph-selinux-10.2.2-5.el7cp.x86_64 libcephfs1-10.2.2-5.el7cp.x86_64 python-cephfs-10.2.2-5.el7cp.x86_64 rhscon-agent-0.0.13-1.el7scon.noarch How reproducible: 100% Steps to Reproduce: 1. add USB *Removable* device to one machine before accepting of nodes 2. accept nodes 3. try to create cluster and check "Raw Capacity" if there is also counted this drive Actual results: Removable device is counted to "Raw Capacity". Expected results: Removable device should be completely ignored in Console.
