Hi all, I've just updated our Galaxy to the current release 26920e20157f which now includes quota support. This means I need to run set_dataset_sizes.py in order to record the current usage, as explained here: http://wiki.g2.bx.psu.edu/Admin/Disk%20Quotas However, I have run into a problem: $ sudo -u galaxy python2.6 scripts/set_dataset_sizes.py Loading Galaxy model... Processing 3011 datasets... Completed 0% Traceback (most recent call last): File "scripts/set_dataset_sizes.py", line 45, in <module> dataset.set_total_size() File "lib/galaxy/model/__init__.py", line 702, in set_total_size if self.object_store.exists(self, extra_dir=self._extra_files_path or "dataset_%d_files" % self.id, dir_only=True): AttributeError: 'NoneType' object has no attribute 'exists' According to the comments in that file, self.object_store should be initialized in mapping.py (method init) by app.py - apparently that isn't happening. Has anyone else seen this? Thanks, Peter
