Title (EN) INPUT/OUTPUT(I/O) FENCING WITHOUT DEDICATED ARBITRATORS
(FR) ISOLEMENT D’ENTRÉE/SORTIE (E/S) SANS ARBITRES DÉDIÉS
Abstract:
(EN) Disclosed herein are methods, systems, and processes to perform input/output (I/O) fencing without dedicated arbitrators. A coordination storage identifier is stored in a storage device as metadata. The coordination storage identifier is associated with a node of a cluster coupled to the storage device, and an I/O fencing operation is performed using the coordination storage identifier.
(FR) La présente invention concerne des procédés, des systèmes et des processus pour effectuer un isolement (fencing) d’entrée/sortie (E/S) sans arbitres dédiés. Un identifiant de stockage de coordination est stocké dans un dispositif de stockage sous forme de métadonnées. L’identifiant de stockage de coordination est associé à un nœud d’un cluster couplé au dispositif de stockage, et une opération d’isolement E/S est effectuée au moyen de l’identifiant de stockage de coordination.
