Hi, in a program after reading a file I did a gpfs_fcntl() with GPFS_CLEAR_FILE_CACHE to get rid of the now unused pages in the file cache. 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. Is that expected behaviour or an unexpected feature (aka bug)? -- Dr. Jürgen Hannappel DESY/IT Tel. : +49 40 8998-4616 -------------- next part -------------- A non-text attachment was scrubbed...
