I am creating a GeoServer 2.4.1 store with GeoTiffs using the Image Mosaic Plugin and I get the following error when pressing the button

Could not list layers for this store, an error occurred retrieving them: 
Failed to create reader from file://C:\Geoserver Rasters\GeoTiffs\ and hints null

The Shape File describing the GeoTiffs IS Created in the directory.

I have tied with a single GeoTiff as well as multile files, same error.

I CAN create a store with the single tif file using the GEOTIFF Raster Data Store successfully but when using the ImageMosaic Plugin, it fails

Is there a problem with the file? How to I get these GeoTiff Files to display?

GDALINFO Reports the following on the single test file:

Check the file system permissions for your data directory.

Your servlet container like Tomcat or jetty needs to be able to read AND write files in the directory.

I had the same error using linux bu after correcting the permissions for that specific directory (chown -R tomcat7:tomcat ) everything was fine.

Try to put your geotiffs in a directory like this:

...\webapps\geoserver\data\data\myGeoTiffs

Much more, when creating you store, put this in the Connection Parameters URL:

file:data/myGeoTiffs

I've tried also to reproduce your error on my systems but I wasn't able to do it. (In my case everything works well even when I load the tiffs from anywhere outside the GeoServer data directory).

I think there could be another two possible causes:

1) Something wrong with your data:

Therefore, is it possible for you to upload on dropbox.com a zip with your data to be tested outside your computer? If it loads ok on mine computer then your ImageMosaic Plugin could be incompatible with your GeoServer version.

2) If the error appears again, then maybe the GeoTiffs wasn't properly produced:

In this case:

a) You could use gdal_translate, which could clean up the errors in the GeoTiffs headers.

b) Another approach would be to produce a vrt for your tiles. I've upload already such a mosaic here, for you, to test it.

Also, there is possible to see important hints about the error, when you try to create the store, if you check the GeoServer log.

For me, it was spaces in the filename that I had to remove (GeoServer v2.14) and then it worked.

It's been quite some time since this question was asked but I faced a similar issue today.

In GeoServer Web UI, check the logs under About & Status > GeoServer Logs. It's likely that there's an answer there. In my case, the error occured because the directory was not writable. Changing it to rwxrwxrwx (0777) fixed the issue.

Good luck :)

I had the same problem, and in my case changing the permissions(write) on the files fixed the problem.

For me, it happened because I was using Windows file paths (with backslashes \ instead of /). Changing the url to use normal slash characters solved it for me.

Check this thread, it worked for me https://groups.google.com/forum/#!topic/geoserver-manager-users/sa1D4kRr62A

In short, the point is if the server hostname does not resolve to an IP address (weird behavior of JAI ImageIO...) the store creation fails. Ensuring that the hostname resolved corrected the problem for me.

For me it was Linux systemd restricting the dirs that tomcat is allowed to write to.

In your tomcat.service file, make sure to add the necessary ReadWritePaths. (note: your service file may be named differently. eg geoserver.service)

eg:

ReadWritePaths=/opt/geoserver/data/
ReadWritePaths=/path/to/your/images/dir/

Also I found that when ImageMosaic plugin creates the dirname.properties file, it set Heterogeneous to true and added MosaicCRS. One of these cause problems when I was creating a layer from the data source. Changing Heterogeneous to false and commenting out MosaicCRS seemed to fix it.

I had the same problem twice. And it was two different reasons:

  1. HDD was failing and Linux set it as read only.
  2. I tried to load files from mounted HDD that had label containing the space char.
