Sorry, i have not that error, i only point you to that conversation.
I found the following explenation:
Hard floats use an on-chip floating point unit. Soft floats emulate one in software. The difference is speed.
Ok, but then both variants should work!?
Upgrading is a bid the same as installingā¦ Place the zip in the public en run it.
The installer script will move the old openHAB2 folder to openHAB2-bakcup_DATETIME and then install openHAB2 in a new openHAB2 folder. afterwards the script should copy the userdata folder from the bakcup to the new openHAB2 directory.
But that failed for me. so i did the copy myself and after that did a chown -hR openhab2:users openHAB2 and chmod -R u+w openHAB2/userdata
(i think the failing is because the scrip does a copy with -avr and i think the -v is giving problems, but that i have to try with the next upgrade 
In all upgrading is nothing more than replacing the runtime folder with a new folder.
If you have 7zip open the spk file go to the script folder and open installer.sh. search for the postupgrade() and look wat it is doing.
Look at https://www.synology.com/nl-nl/knowledgebase/DSM/tutorial/General/What_kind_of_CPU_does_my_NAS_have if youāre dutchā¦ search your DS213 and you see if has no FPU ā¦ so you need java with a software floating point system.
One more question - i cant edit rules via habmin rule web editor, save button allways disabled, is it happens only with me?
I have the:
DS213j Marvell Armada 370 88F6707 Single Core 1 Ja Armada370 DDR3 512 MB
āJaā means, it has as Floatingpoint unit.
The installed Java version does not rally say if it is a hard or soft version:
Currently I run my Openhab on my central heating control windows PC, an old ACER One netbook.
This works during Winter time for me, but in summer I want to shut it off. Then latest I have to switch to the Diskstation.
The Acer is already heavy loaded with OH, around 50% CPU load (The Viessdata application only takes about 5%)
@HolgerL, Should you not be better of with a PI3 PC this is stand alone can run of a 12V battery and has more then enough CPU power.
The DS213j is a 16bit BUS i think this has to do with your error ā¦ see http://www.synology-wiki.de/index.php/Welchen_Prozessortyp_besitzt_mein_System%3F
Read this artikel. https://pcloadletter.co.uk/2011/08/23/java-package-for-synology/ if Iām correct this will install or give you the instruction to download the correct java version.
I found this site also, and this is the version I installed! 
Sure you are right with the PI3, but in the first step I tried to use a Hardware which is anyway running and consuming power. If this in then end does not work, I will add the PI3.
Then Iām out of ideas what the problem can beā¦ let us know if you solved it.
The change log at pcloadletter https://pcloadletter.co.uk/2011/08/23/java-package-for-synology/ says:
042 07/Jan/17 ā Updated to Java 8u111, fixed Armada 370/XP systems running DSM 6.0 which had switched from soft to hard float ABI
Unfortunately I find his application will only load the soft float version ejdk-8u121-linux-arm-sflt.tar.gz
I have given him feedback and hope he will be able to confirm my report and update his application.
One option I tested is to rename the Oracle package. So when I renamed ejdk-8u121-linux-armv6-vfp-hflt.tar.gz to ejdk-8u121-linux-arm-sflt.tar.gz, Java loaded and OpenHAB seems OK.
What I originally did is use the native Synology Java8 Package and loaded jdk-8u121-linux-arm32-vfp-hflt.tar.gz After install the Karaf error went away and OpenHAB worked on my DS414.

Hi,
Iāve found this topic when I had the same issue as some other people in this thread.
I already had a pretty good basic set up of OpenHab 2.0. I wanted to upgrade to OpenHAB 2.1. Iāve found the SPK file ā2.1.0.003-SNAPSHOT-DSM6ā on GitHub and I installed it (I didnāt uninstall the 2.0 version first).
The result was similar to several people above: all openHab files (including config) were gone, except for a few .sh files. And I didnāt make a recent backup (I know, I got myself to blame). I didnāt find the openhab-backup- folder that should have been created.
The recent (yesterdayās) SPK file (2.1.0.004-SNAPSHOT-DSM6) had the same outcome.
Iāve downloaded @levers version (OpenHAB-2.1.0.002-SNAPSHOT-DSM6-syno-noarch-0.003.spk.pdf) mentioned three days ago in this thread. This one installed OpenHAB 2.1 correctly (with putting the openhab-2.1.0-SNAPSHOT.zip in the public-folder).
Thanks, levers!
My lessons learned: backups, backups backups! (I knew that one already )
Hi all,
I released a new version:
https://github.com/openhab/openhab-syno-spk/releases/download/2.1.0.004-SNAPSHOT-DSM6/OpenHAB-2.1.0.004-SNAPSHOT-DSM6-syno-noarch-0.001.spk
There is no difference between my and @levers package!
Try it!
Thanks,
Chris
Hi,
Using the Synology package 2.1.0.003 I have installed OpenHab 2.1.
What is the best approach to upgrade to a newer snapshot without losing your config data?
I am trying to get OH2 running on my DS216+II . Java is running, even OH2 is starting and I can access PaperUI.
I used: OpenHAB-2.1.0.004-SNAPSHOT-DSM6-syno-noarch-0.001 (1).spk
But starting OH2 I get following entry
In directory /volume1/@appstore/openHAB2 mounting looks ok but I can not access conf: permission denied
Any idea what I am missing ?
Thx.
I solved the issue, I had to change the owner of the openHAB2 folder to the openhab2 user
Thx
I did a fresh install this weekend with the 004 package and had no issue.
The only thing i did was create the folders on the public location and modified the rights to all users for public.
Openhab is running fine with java 8 from pc loadletter.
And indeed all files aād folders need to be on openhab2 user.
I also gave openhab 2 user rights to admin group
Symlinks where autocreated on install for the conf and services.
Regards Wolf
Hello everybody,
Iām trying to get OH2 running on my DS216j, but until now Iāve got no luck.
Here is a brief summary of all things Iāve done by now.
- the folder /volume1/public/openHAB2/conf and /volume1/public/openHAB2/addons exists
- everyone has the permission to r/w for /volume1/public/ and all folders inside
- Java SE 8 by PCLoadLetter is running
- The Installation of OH2 (2.1.0.004-SNAPSHOT) works fine, I placed the .zip file in /public/openHAB2
- the openhab2 user is the owner of the folder /volume1/public/
- I also tried to copy the folders /conf and /addons by myself to /public/openHAB2
If I trie to start OH2 by clicking on the URL of OH2 in the package center, I always get the message āSafari cannot open the pageā ā¦
After trying to start OH2, I get the following:
I think the folders and the rights are all fine:
I really donāt get it, what am I missing?
Can anybody help me?
Thx
Instead of trying to install via .Zip, download the latest .SPK file here.
Then open package center in DSM and click Manual Install, load the .SPK file and it should install it as a package. Found here.
Good luck!
First of all thanks for the fast reply.
But Iām sorry, I forgot to tell you that I used the latest .spk file (2.1.0.004) from here (Releases openhab) for the installation.
But if I just use the .spk file the folder /volume1/@appstore/openHAB2/ was empty.
So I downloaded the .zip-file my self and placed it in the public folder.
Installation workes fine, but if Iām trying to start OH, I get the log file from above.
Alexander, it seems like the port 8443 of Openhab is used by some other service like domoticz. Go to /volume1/@appstore/openHAB2/runtime/bin folder. As root āvi setenvā. Change HTTPS_PORT=8443 line to HTTPS_PORT=8445. Save and quit. Restart openHAB service in package center.
