I bought a QNAP TS-453mini in order to replace the good old Synology DS409slim. Not that it doesn’t work. It’s just that the 4x 1TB disks are nearly full. I was desperately waiting for bigger 2.5″ capacity but this doesn’t seem to happen. Also, since I moved into a new place, I planned to also reduce the number of plugged)in stuff. Hence, the fanless OpenBSD server would either go in the Cloud or… on the QNAP virtualization software.
My DS409slim is really slow since I faked it as a DS411j and installed DSM v5 on it. An option could be configuration issues. So I decided to reset the whole configuration. But I need to keep all that are stored on the SHR-RAID. It is quite straight forward. But here’s the no-so-short story.

Since I turned my DS409slim into a DS411j, I have access to DSM updates. So tonight, I upgraded from DSM 5.0-4528 Update 1 to 5.1-5004 using the update wizard. So far, everything went OK. On first reboot, I was recommended to keep my DSM up-to-date using automatic upgrade. As I don’t want my NAS to reboot while I’m working on it, I choose to “Download DSM updates but let me choose whether to install them”.
That’s all about it 🙂
Looking at the DiskStation DS414slim, I discovered that DSM was now available in version 5. But it wasn’t available from the DSM 4.2 control panel on my DS409slim. After a few Internet diggings, I learned that it should be possible to install DSM5 on a DS409slim. The main trick is to fake another DS. Looking at CPUs in Synology’s NAS, you can see that DS409slim and DS411j share the same Marvell Kirkwood mv6281 CPU and 16-bit@DDR2 architecture. That’s the trick to be able to use DSM5 on DS409slim.
I own a Synology DS409slim on which I have enabled SSH. The primary idea was just to have a look behind the hoods. This is quite simple: browse to the configuration panel, select the terminal services section and active the SSH daemon.
But once there, you’re stuck with a basic shell and a few commands. No `less`, no `grep`, no `bzip2`, no `perl`… Synology provides an official packages repository that provides a few extra features ; like VPN, LDAP and such ; but not so much to get a “complete” UNIX environment. The savior here is called “ipkg”. Quoting Wikipedia: “(…) the Itsy Package Management System (ipkg), is a lightweight package management system designed for embedded devices that resembled Debian’s dpkg. (…)”. It provides a bunch a GNU-like tools and it runs on the Synology!
