- The pool list is a card per pool, two to a row, as the host
Overview's Hardware and Software cards: its name with Active or
Stopped and Autostart badges in the header, then its type, its path
(an RBD pool's Ceph pool), its volume count and its space as the
Overview shows it (computes/pool_bar.html, without the name again);
a stopped pool's space is unavailable, not zero.
wvmStorages.get_storages_info gives the path, autostart and percent
used, which computes.views.host_pools computed for itself.
- A pool's page has a Space card (percent, used of size, of what: the
filesystem of its path, its volume group or the Ceph cluster, which
other pools may share; free) and a Pool card (state, autostart,
type, path) instead of a two-column list mixing facts and forms.
Start or Stop is its heading's button; autostart and deleting a
stopped pool are in its menu; the confirmations stay.
- The volume table drops the row number; a volume's capacity and what
it has allocated share a column hidden on a phone; its format is a
badge; its actions are one group, Clone and a menu with Delete,
named for the volume.
- "New pool", "New volume" and "Upload ISO" are labelled buttons
instead of bare green pluses; their dialogs' titles name them.
- The New pool dialog is one form (design reviewed with Codex): the
pool's type as radio cards, as the VM create page chooses its disk
source (their style moves to webvirtcloud.css), one name, and only
the chosen type's fields, the others hidden and disabled.
- A directory's or a share's mount path follows the name
(/var/lib/libvirt/<name>) until it is edited: no default path of
another pool any more.
- ISO images is a directory preset named iso; when the host has an
iso pool, a card links to it instead.
- Ceph offers the host's Ceph secrets by their names, not every
secret by UUID; without one it says so and links the Secrets page.
- LVM asks to agree that the device is erased, the server too.
- AddStgPool checks each type's fields, a name or a path another
pool has, an RBD secret that is not one of the host's Ceph secrets,
and the names "." and "..". A refused pool, or one libvirt refuses,
opens the dialog again with what was entered, the reasons beside
the fields and focus on the first; the audit row for a taken name
stays.
