Steps

An instance does not always use the permanent directory you configured: an unset or unwritable value falls back to the temporary directory. This reads the one actually in use. You need programming rights on the wiki.

1. Create a page with the Wiki editor and insert this script:

   {{velocity}}
   $services.component.getInstance('org.xwiki.environment.Environment').getPermanentDirectory().getCanonicalPath()
   {{/velocity}}

2. Click "Save". The page renders the absolute path of the directory in use:

   /var/lib/xwiki/data

FAQ

Why do I get an error when I save the page?

The script needs programming rights, which it only has when the page was last saved by a user who holds them.

Is there a way that does not need a script?

Yes. The startup log carries the line Using permanent directory [...], which reports the configured value rather than the resolved absolute path.
