been using OMV for a few years (beginning of 2016) now and in the beginning added two 4TB drives in Raid 1. After a long time with no problems I now finally decided to buy a new 4TB drive to replace one of the old ones and keep that one as a backup.
Now the problems start: My disks are somehow formated with a MBR. I can use the whole 4TB though.
Everything I can find online says this is not really possible, although you could fiddle with the sectors and make it happen. Still: When trying to copy the MBR to write to the new drive it gives me an error.
So...what to do now? Any ideas or topics to look for?
