Clustered computer environment partition resolution |
摘要 |
According to one aspect of the present disclosure, a method and technique for clustered computer environment partition resolution is disclosed. For a clustered environment having a plurality of nodes, the method includes: creating a key by a first node of the plurality of clustered nodes, the plurality of clustered nodes each configured to have access to a storage provider resource; communicating the key to remaining nodes of the plurality of clustered nodes; responsive to detecting a potential partition event, generating by at least one of the plurality of clustered nodes a lock code using the key for reserving the storage provider resource; and responsive to determining an unlocked status of the storage provider resource, resolving the partition event by writing the lock code to the storage provider resource. |
