[SOLVED] Synology SVN Server wrong FS format

[teha]

Hey guys,

I am currently struggling with the file system format of one of my SVN repositories.

I have a Windows Server at home, running with a SVN server software. I created a FSFS SVN repository on that server a while ago. The server software automatically created that repository with the SVN file system format 8 (which is the most recent one, afaik). Running so far!

Now I tried to move my SVN repositories onto my Synology NAS with a current DSM version installed. I installed the SVN server package on the NAS, created a new repository and then moved the /db directory from my existing FS format 8 repository into the /db folder in the repo's folder on the NAS.

But now, if I want to check out a working copy, I get this error message:
"Expected FS format between '1' and '7'; found format '8'" I have SVN 1.14.x installed, which should be fine. I also tried this with another (older) repo with FS format 4, that worked fine this way!

So my question is now: Is this an issue of the SVN server on the Synology NAS? Is it too old?
Because when I check the SVN directory via SSH, I get this:

USERNAME@HOSTNAME:/volume1/@appstore/SVN/bin$ ll
total 2520
drwxr-xr-x 2 root root    4096 Aug 16  2017 .
drwxr-xr-x 7 root root    4096 Jul  6 11:56 ..

-rwxr-xr-x 1 root root   82332 Aug 16  2017 svnmucc
-rwxr-xr-x 1 root root  177132 Aug 16  2017 svnrdump
-rwxr-xr-x 1 root root  297248 Aug 16  2017 svnserve
-rwxr-xr-x 1 root root  138712 Aug 16  2017 svnsync
-rwxr-xr-x 1 root root   38792 Aug 16  2017 svnversion

The files are from 2017. That's the reason I came to the conclusion, the version may be too old.

Are there newer versions of the SVN server running on Synology NAS available and, if yes, could I replace the files in the folder above with newer files?

Looking forward to your comments.

Thanks,

Hey guys,

after thinking about it and searching even more on the web, I finally found a working manual for me and I want to share it with you.

http://www.darioniedermann.it/docs/downgrade_svn.html

I created a dump file with a current SVN client (TortoiseSVN 1.14) and then created a new Repository with a old version of Slik SVN 1.8. Then I used the svnadmin-Tool from the old Slik SVN version to do a "svnadmin load"... (see step 4 in the manual above).

This way, I was really able to downgrade from FSFS format 8 to 6 and thus to be able to use the repository. I will now check if everything works but it looks good at the first glance.

Last step: Delete all files in the folder "db" on the server. Then, copy all files from the folder "db" from the newly created format 6 repository to the folder "db" on the server. Keep the files in all other folders (next to "db") to keep settings and user credentials.

I hope this helps someone else with this problem.

Best regards,
teha
