Hi all, I've been using OMV for a few years and decided to upgrade my old OMV "2.xx" to 4.
However install repeatedly fails installing grub ...
I have 2x USB, both new and were blank until a couple of hours ago. One is imaged with the source iso, openmediavault_4.1.3-amd64.iso, and the other is to be used as the system drive. All other drives are disconnected.
The installation assigns sdb for the destination drive, and I see it attempt "grub-install /dev/sdb"
That's where it fails
When I try it manually from shell I get:
"grub-install: error: cannot delete '/boot/grub/i386-pc/serial.mod' : Read-only file system"
Help please, I know virtually zero about this sort of thing.
