Storage-eas read-only during configuration change

Filed under: Uncategorized — Michael Weiner @ 11:08 am

[Update 1/9/23 10:58 AM]

The migration of storage-eas data to a new location is complete, and full read/write capability is available for all research groups on the device. Researchers may resume regular use of storage-eas, including writing new data to it.

Thank you for your patience as we completed these configuration changes to improve stability of storage-eas. Please email us at pace-support@oit.gatech.edu with any questions.

Summary: Researchers have reported multiple outages of the storage-eas server recently. To stabilize the storage, PACE will make configuration changes. The storage-eas server will become read-only at 3 PM today and will remain read-only until after the Winter Break, while the changes are being implemented. We will provide an update when write access is restored.

Details: PACE will remove the deduplication setting on storage-eas, which is causing performance and stability issues. Beginning this afternoon, the system will become read-only while all data is copied to a new location. After the copy is complete, we will enable access to the storage in the new location, with full read/write capabilities.

Impact: Researchers will not be able to write to storage-eas for up to two weeks. You may continue reading files from it on both PACE and external systems where it is mounted. While this move is in progress, PACE recommends that researchers copy any files that need to be used in Phoenix jobs into their scratch directories, then work from there to write during a job. Scratch provides each researcher with 15 TB of temporary storage on the Lustre parallel filesystem. Files in scratch can be copied to non-PACE storage via Globus.

Thank you for your patience as we complete these configuration changes to improve stability of storage-eas. Please email us at pace-support@oit.gatech.edu with any questions.
