-* A component of the /project filesystem malfunctioned while returning to service as described [http://status.computecanada.ca/incident/104 here].  Some details of the restoration process:
+Nothing to report at this time.
-** A list of affected files (.files_being_restored) is in the base directory of each project.  For privacy reasons, this list is only readable by the project owner (sponsor or PI).
-** Affected files behave oddly: they cannot be removed (because they make reference to an offline storage component, so a failure is returned when trying to deallocate).  They can be moved, though (the "mv" command doesn't work though.)  Affected files will show up in directory listings with "?" in some fields.
-** We are restoring files to a separate location, then moving the broken file elsewhere, and moving the restored file into place.  This is happening incrementally, and every restored file is noted in another per-project list (.files_restored).
-** Based on the overall number of files affected, we expect the entire process to take 8-10 days.  The particular order of files restored depends on tape scheduling, so is difficult to predict.
