Stale File Handles on GPFS clients

OSC is experiencing some problems with the Project and Scratch filesystems that are resulting in some jobs seeing "stale file handles". We are investigating the problem and will provide updates as we have them. Job scheduling is currently paused on all filesystems.

We are working with vendor engineers to resolve the issue, but you can currently still log in via SSH and access your files in your home directories. OnDemand logins will likely hang, and attempts to access files on Project or Scratch will likely fail.

Project space giving errors "No space left on device"

11/01/2016 11:52AM Update: This issue has been fixed. 

We have become aware of a problem with the Project storage space that gives errors "No space left on device". The cause is that the metadata subsystem is full. This issue might result in failures of users' jobs. 

We are working hard to fix this issue as soon as possible and really apologize for any inconveniences this may cause you.
