The ALCF will upgrade the theta-fs0 filesystem during planned maintenance from Monday, May 2, to Wednesday May 4, 2022. Cooley will undergo regular planned maintenance and be returned to service on May 2. After the Cooley maintenance, theta-fs0 filesystem will be unavailable until the filesystem upgrade is complete. Please note that /projects uses theta-fs0. The Globus endpoints will be paused during maintenance and unpaused after without /lust/theta-fs0 or /projects. If you are not using theta-fs0 on Cooley, please follow the guidance at: https://www.alcf.anl.gov/support-center/theta/running-jobs-and-submission-scripts#qsub_filesystems. If you do not specify any filesystem, then the job will be tagged as requesting all filesystems (including theta-fs0) and will put on hold unnecessarily until the filesystem upgrade is complete.
