I am in the process of setting up a media server based on OMV and intend to use RAID 5 for the data storage. Ideally I want start with a single 8 TB drive (which will be big enough for a while) and then add more as and when finances allow. But can I do this without having to backup, format and copy it all back again?
Ideally I'd like to start with a single HD on it's own. Then add another identical HD for security (not additional storage) then be able to add another to grow the size of the array (and then another etc.). Would this be possible?
I am fully aware of what RAID means and not being a backup, that is not the issue. It's just how OMV's RAID implementation (MD I believe) can cope with growing from a single independent HD to an array of 5 drives. So hope someone can advise.
