I haven't decided on installing OMV yet because I've got two HDDs with one volume EXT4 each.
A 3rd HDD is for the OS, so far this has been a plain Lubuntu. And this could be for OMV on a new setup.
BUT- will OMV require me to reformat the two storage drives, in which case all data will be lost (or will have to find a temporary place). Not keen on that.
So can storage drives be mounted after installation without reformatting them?
