System, method and computer program product for clustered computer environment partition resolution

Abstract

According to one aspect of the present disclosure, a system and technique for clustered computer environment partition resolution is disclosed. The system includes: a first node couplable to a second node in a clustered network environment; and a storage provider resource accessible by the first and second nodes. The first node comprises logic executable to: create a key; communicate the key to the second node; responsive to detecting a potential partition event, generate a lock code using the key for reserving the storage provider resource; and responsive to determining an unlocked status of the storage provider resource, resolve the partition event by writing the lock code to the storage provider resource.

         8 . A system comprising:
 a first node couplable to a second node in a clustered network environment; and   a storage provider resource accessible by the first and second nodes; and   wherein the first node comprises logic executable to:   create a key;   communicate the key to the second node;   responsive to detecting a potential partition event, generate a lock code using the key for reserving the storage provider resource; and   responsive to determining an unlocked status of the storage provider resource, resolve the partition event by writing the lock code to the storage provider resource.   
     
     
         9 . The system of  claim 8 , wherein the first node is configured to, responsive to creating the clustered environment, create the key. 
     
     
         10 . The system of  claim 9 , wherein the first node is configured to allocate to each of the first and second nodes an account with the storage provider resource. 
     
     
         11 . The system of  claim 8 , wherein the first node is configured to provision the storage provider resource in a cloud environment. 
     
     
         12 . The system of  claim 11 , wherein the first node is configured to:
 responsive to detecting the partition event, access the storage provider resource; and   determine a lock status of the storage provider resource based on the key.   
     
     
         13 . A computer program product for partition resolution in a clustered network environment having a plurality of nodes, the computer program product comprising:
 a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising computer readable program code configured to:   create 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;   communicate the key to remaining nodes of the plurality of clustered nodes;   responsive to detecting a potential partition event, generate a lock code using the key for reserving the storage provider resource; and   responsive to determining an unlocked status of the storage provider resource, resolve the partition event by writing the lock code to the storage provider resource.   
     
     
         14 . The computer program product of  claim 13 , wherein the computer readable program code is configured to, responsive to creating the clustered environment, create the key. 
     
     
         15 . The computer program product of  claim 13 , wherein the computer readable program code is configured to provision each of the plurality of clustered nodes with an account with the storage provider resource. 
     
     
         16 . The computer program product of  claim 13 , wherein the computer readable program code is configured to provision the storage provider resource in a cloud environment. 
     
     
         17 . The computer program product of  claim 13 , wherein the computer readable program code is configured to:
 responsive to detecting the partition event, access the storage provider resource; and   determine a lock status of the storage provider resource based on the key.
