Graham (GP3) Graham cluster now available - Graham de nouveau disponible

Graham cluster now available.

The Graham cluster is now operational and has been returned to service.  We thank you for your patience and apologize for the extended outage; however, the facility upgrades were required.  The data centre now has dual 3MW transformers for reliability and to handle the future expansion of Graham. Our protected power supply is now provided by two separate UPS systems, each backed by their own generator; this enhances reliability of storage as well as other critical services.

When restarting the cluster, we did encounter a problem with the /project file system.  We were able to correct the problem, but a portion of the file system became corrupted and has required us to restore that data from our tape backup system.  This affected about 2% of all files stored in /project. A list of impacted files has been placed in a file named .files_being_restored in each group’s project directory.  This file is owned by and only readable by the group’s PI by default to maintain privacy.  Those files will be restored to their original locations as quickly as the tape system is able to recover the data.   

Graham de nouveau disponible.

Graham est de nouveau en service. Les modifications à l’alimentation en électricité de l’édifice étaient nécessaires et nous sommes désolés des inconvénients que cet arrêt de service prolongé a pu occasionner. Les installations sont maintenant dotées de deux transformateurs de 3MW qui augmentent leur fiabilité et leur capacité de recevoir des ajouts futurs. Graham sera dorénavant desservie par deux systèmes ASI (alimentation sans interruption) distincts, chacun pourvu d’un générateur de réserve, ce qui procure une meilleure fiabilité de service.

Une portion du système de fichiers /project a cependant été corrompue à la réinitialisation de la grappe. Environ 2 % des fichiers stockés sur l’espace /project ont été touchés. Ils sont listés dans un fichier nommé .files_being_restored qui se trouve dans chacun des répertoires de groupe. Pour des raisons de confidentialité, le chercheur principal du groupe est propriétaire de ce fichier et seul autorisé à en lire le contenu. Les fichiers qui ont été corrompus seront récupérés du système de sauvegarde dans les meilleurs délais. An update is occuring at this site. Une mise à jour est en cours sur ce site.
