I have subversion on sun solaris.
First, I need to create a respository as below:

svnadmin create /usr/local/repos --fs-type fsfs

and I got an error as below:
svnadmin create /usr/local/repos --fs-type fsfs

I have been looking for book, intenet and the web site help
http://subversion.tigris.org/. But I don't have any clues.

Please help.
Thanks in advance.
