i‘d like to build on a Gen8 Hp Server

My server is upgraded to XEON E3-1320v2

 

Hi Holger,

 

Did you succeed? What did you upgrade from?

@Niels_Jthe gen8 will happily run DSM 6.2.3 with jun’s 1.03b loader or if you want to try DSM 7 you can build a loader using redpill tinycore, see the thread in the developer discussion section.

Thank you for the info!
The 6.2.3 is the one in the first post in this thread, correct?
And now for the absolute 100% noob question:  Do I just place the img-file on the USB stick, or do I need to edit something in the file and compile it with ... etc ? If so, where might I find the programs for it?

For Jun's Loader yes, you need to open one of the partitions and edit the grub file with the appropriate S/N and Mac Address.

Hi folks,

I had to reboot my machine, wondering that the GUI doesn't show up. Connected a monitor to the server and found a GRUB warning, saying: error incompatible license entering rescue mode....

 

Has anyone an idea what this means and how to get my server booting again?

Thanks for any helpful advice

you coud try to rebuild the loader on a new usb flash drive

that the vanilla loader edit grub.cfg to mach the usb vid/pid of the new  usb flash drive

copy zImage, rd.gz and extra.lzma from old usb to the new one (all files on 2nd partiton)

the try if the system boot again (if that work you can transfer SN and nic's mac from the olf grub.cfg to the new one)

that way you dont change anything to what it is now, ols usb and system would still be the same if this attempt is a no good

Hi 

thanks for your answer. I have simply recorded the USB bootstick with a new image. I did this about 4 years ago the last time - and I had a lot of jitters. But in fact it was much easier and faster under macOS than I feared.
Now everything works again and my Synology version is finally on DSM 6.2.3-25426 Update 3

Hi all.

I want to create a duplicate copy of my usb flash that has the jun”s loader on it.. in the past my usb drive died and I had to create a new one but I guess perhaps due to the vid/pid being different, It started my xpenology box as being new and I had do sort of a recover and restore data type of thing etc…

if I create a copy of my current usb drive, should I use its vid/pid of the original drive in the cfg file on the new drive to prevent the loader from initializing the xpenology box if I ever have to swap out the usb loader flash drive?

[signigelchan]

you're the best jun!

[nickybg87]

Is there a way to change the SN in the grub.cfg remotely (by ssh maybe) given the fact that pid & vid are set and the drive is not visible?

To have correct MAC address for NIC you need to change it in /grub/grub.cfg file before booting NAS but if you forgot, there is still a chance to do it (and change serial number as well). To do so we need to change grub.cfg file on internal flash (see above).

/dev/synoboot do not show in mount nor fdisk -l but still if you run 

fdisk -l /dev/synoboot 

you should see:

Disk /dev/synoboot: 119.5 MiB, 125304832 bytes, 244736 sectors <- (size depends of usb drive used, here it is internal flash of Netgear ReadyNas Pro2)
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

Disklabel type: gpt
Disk identifier: AFB38D11-BCEA-4409-B348-F4FEEE602114
Device         Start    End Sectors Size Type
/dev/synoboot1  2048  32767   30720  15M EFI System
/dev/synoboot2 32768  94207   61440  30M Linux filesystem
/dev/synoboot3 94208 102366    8159   4M BIOS boot

Create folder somewhere (/) and mount first partition from above 

mount -o loop,offset=1048576 /dev/synoboot /temp

where offset is sector size(512) multiplied by start sector of 1st partition(2048). 

Now you should have access to grub.cfg in grub folder.

Change mac1 and mac2 to correct hardware addresses.
After writing to file you can unmount /dev/synoboot and reboot to check if changes applied correctly.
