Error when importing backup

I just installed a fresh xwiki and I want to import the data from the standalone version we used to test the product.But I’m getting an error after the upload of the .xar (800 Mio)

In /var/log/tomcat9/catalina.out, ther is a message :

[2020-03-30 18:04:43] [info] com.xpn.xwiki.XWikiException: Error number 11008 in 11: Exception while parsing uploaded file

The message is in french “Aucun espace disponible sur le périphérique”
and the translation is : “No space available on the device”

But I dont’t see where there is not enough space

I thought it was the /tmp but I don’t know how change the path for xwiki

Hi, see

Thank you for this quick answer

Here’s what I got with this code :


result :


#ls -l /var/lib/xwiki
total 4
drwxr-xr-x 7 tomcat tomcat 4096 mars 27 16:05 data

#ls -l /var/cache/tomcat9/Catalina/localhost/xwiki/
total 4
drwxr-x— 6 tomcat tomcat 4096 mars 30 18:13 xwiki-temp

tomcat can write in both folders and /var has 13Gio left.
So what’s wrong ?

The directories you look at, are the directories used by XWiki. Maybe some 3rd party lib we use use another tmp dir. Stack trace says:

So it seems Commons FileUpload is trying to save some content on the file system somewhere.

From what I see in commons fileupload source code, it uses the “” system property:

    protected File getTempFile() {
        if (tempFile == null) {
            File tempDir = repository;
            if (tempDir == null) {
                tempDir = new File(System.getProperty(""));

            String tempFileName = format("upload_%s_%s.tmp", UID, getUniqueId());

            tempFile = new File(tempDir, tempFileName);
        return tempFile;


Try this:


print System.getProperty('')

print System.getProperty('') returns /tmp and it has only 431M left

I tried to add JAVA_OPTS="${JAVA_OPTS}" in /etc/default/tomcat9 or modify the environment variable with export
but nothing seems to work.

FYI, I’ve updated

The leading underscore seems wrong. There are several ways to configure and start Tomcat. I’m afraid you’ll need to check the Tomcat docs. But what you did seems ok.

@tmortagne BTW, is it expected that the upload of a file in xwiki is not using the xwiki tmp dir?

As a matter of fact, it’s not. But it’s useless for xwiki.

I’m going to dig deeper into the Tomcat docs.
Merci pour tout :wink:

Actually it’s a fallback only. Need to find what is the value of repository.

ok found this code:

    public void loadFileList(XWikiContext context) throws XWikiException
        XWiki xwiki = context.getWiki();
            xwiki.getSpacePreferenceAsLong(UPLOAD_MAXSIZE_PARAMETER, UPLOAD_DEFAULT_MAXSIZE, context),
            (int) xwiki.getSpacePreferenceAsLong(UPLOAD_SIZETHRESHOLD_PARAMETER, UPLOAD_DEFAULT_SIZETHRESHOLD, context),
            xwiki.Param("xwiki.upload.tempdir"), context);

So the value of xwiki.upload.tempdir seems to be the value for the repository, and if not writable or cannot create the directory, then it’ll fallback to

EDIT: Confirmed in the comments of

I’ve created

So where do I set xwiki.upload.tempdir ?

in xwiki.cfg but best IMO is to make sure that is set and has enough space since there might be other 3rd party libs using it too. But yes you could try setting it as a test.
