Recommended Posts

I am trying to install

archictecture: broadwellnk

DSM: 7.0.1-7.1.0-42661

drive slot mapping: sataportmap/diskidxmap)


on a


Dell PowerEdge T430

Intel Xeon e5-2623 v4 2.6Ghz, 4c/8t

PERC H330 integrated RAID Controller

Up to eight 3.5" Hot Plug drives

four 1TB 7.2K RPM SATA 6 Gbps 3.5" HDDs, 13g


but I am getting an error:


/usr/local/bin/grub-editenv: error: cannot open `/home/tc/redpill-load/localdiskp1/boot/grub/grubenv': Read-only file system.


After I continue with the commands and reboot the system, there are no Redpill entries in the GRUB menu.


Any idea what is the cause and fix?
