No DM is currently working in any VRE because they get errors when interacting with the Storage system. The issue is when DM tries to write the output of a computation directly on the (volatile) storage system. Here is the stack trace:

com.mongodb.MongoTimeoutException: Timed out after 30000 ms while waiting to connect. Client view of cluster state is {type=UNKNOWN, servers=[{address=mongo-p-vol.d4science.org:27017, type=UNKNOWN, state=CONNECTING, exception={com.mongodb.MongoSocketOpenException: Exception opening socket}, caused by {java.net.ConnectException: Connection refused (Connection refused)}}]
