Hi Giorgio,
perhaps i missed something - but why don't you want to extend the domain by right
click and editing it?

Thank you Elad,
I knew it was required a pvresize command but wanted to be sure that I
wasn't disrupting possible storage parameters bookkeeping by the oVirt
system.
I'm wondering if it's because of this that SD has to be put in maintenance.
Any chance to have the SD resize without putting it offline, for
example doing pvresize on the SPM node and then pvscan on every other
host involved?
I'm sure there are use cases where this is would be of great convenience.
