Abstract: front page image
(EN)Embodiments of the invention relate to block layout and block allocation in a file system to support transparency of application processing. At least one copy of an application is replicated in a write affinity region of a secondary server, and at least one copy of the application is replicated in a wide striping region across a cluster file system. When the application is subject to failure, application processing is transferred from the failure location to the write affinity copy. At the same time, the failed application is rebuilt using the wide striping replication of the application. Once the application is rebuilt, processing may return to the failed location employing the rebuilt application.
(FR)Des modes de mise en oeuvre de l'invention concernent une disposition de bloc et une affectation de bloc dans un système de fichiers permettant de maintenir une transparence du traitement des applications. Au moins une copie d'une application est reproduite dans une région d'affinité d'écriture d'un serveur secondaire, et au moins une copie de l'application est reproduite dans une région de large entrelacement dans un système de fichiers en grappes. Lorsque l'application subit une défaillance, le traitement des applications est transféré de l'emplacement de la défaillance à la copie d'affinité d'écriture. Au même moment, l'application défaillante est reconstruite par reproduction en large entrelacement de l'application. Une fois l'application reconstruite, le traitement peut être renvoyé à l'emplacement de la défaillance à l'aide de l'application reconstruite.
