Clustered computer environment partition resolution

A method for a clustered environment having a plurality of nodes, the method comprising:

• responsive to detecting a potential network partition event, generating a lock code using a key shared among each of the plurality of nodes;
• accessing a storage provider resource;
• determining whether the lock code has been written to the storage provider resource;
• responsive to determining that the lock code has not been written to the storage provider resource, writing the lock code to the storage provider resource;
• and
• responsive to writing the lock code to the storage provider resource, continuing operations as a primary node of the clustered environment.

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 by a processor unit 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 a negative lock status of the storage provider resource, resolve the partition event by writing the lock code to the storage provider resource.

A computer program product for partition resolution in a clustered network environment having a plurality of nodes, the computer program product comprising:

• a non-transitory computer readable 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 a negative lock status of the storage provider resource, resolve the partition event by writing the lock code to the storage provider resource.
