Storage system repurposing with preservation of cluster configuration deltas and data in-place

A method, comprising:

• removing, by a node device comprising at least one processor, a volume associated with the node device from a file system of a computing cluster in which the node device operates in response to an operating system upgrade instruction being received by the node device;
• in response to determining that the volume has successfully been removed from the file system of the computing cluster, populating, by the node device, a partition of the volume with cluster configuration data representative of a configuration of the computing cluster;
• and
• booting, by the node device based on the cluster configuration data as stored on the partition of the volume, the node device from an operating system image installed on the volume.

A non-transitory machine-readable medium comprising computer executable instructions that, when executed by at least one processor, facilitate performance of operations, the operations comprising:

• removing, in response to receiving an operating system upgrade instruction, a volume of a computing device from a file system of a computing cluster in which the computing device operates;
• in response to determining that the volume has successfully been removed from the file system of the computing cluster, populating a partition of the volume with cluster configuration data representative of a configuration of the computing cluster;
• and
• booting, based on the cluster configuration data, the computing device from an operating system image installed on the volume.
