We are continuing to work on the Expanse Lustre filesystem issue. At present we are allowing non-Lustre dependent jobs to run but do have a reservation in place for later tonight for Lustre testing. We will update once the Lustre issue is resolved and continue monitoring the filesystem. Please email help@xsede.org if you have any questions.

We had a reoccurrence of the problem on the Expanse Lustre metadata server. This is affecting access on the /expanse/lustre/scratch and /expanse/lustre/projects directories. We are looking into the issue and will update once it’s resolved. Please email help@xsede.org if you have any questions.
