to get rid of the now unused pages in the file cache.<br>That works fine, but if the file system is read-only (in a remote cluster)
this fails with a message that the file system is read only.<br>Is that expected behaviour or an unexpected feature (aka bug)?<br><br>-- <br>Dr. Jürgen Hannappel  DESY/IT    Tel.  : +49 40 8998-4616<br>[attachment "smime.p7s" deleted by Frederick Stock/Pittsburgh/IBM]
