+Thank you Joey! indeed most likely a \"too fancy\" of a file system.
+
+On [https://www.beegfs.io/release/beegfs_6/Changelog.txt](https://www.beegfs.io/release/beegfs_6/Changelog.txt) I found
+
+
+```
+== Changes in 6.11 (release date: 2017-05-26) ==
+
+General Changes:
+
+* client: Add option sysRenameEbusyAsXdev to return EXDEV instead of EBUSY if
+ rename() is called on open files. (Tools like \"mv\" can handle EXDEV as return
+ value.)
+```
+
+do you think EXDEV would be worked out Ok if that is the culprit? (meanwhile I will let the beegfs users know as well - may be they could try)
