Abstract:
1. A computer implemented method for isolating a workload partition space, the computer implemented method comprising: starting, using a processor and a memory, a boot process of a workload partition in a data processing system using a scratch file system, the scratch file system being in a global space and accessible to an operating system of the data processing system; exporting from the global space to the workload partition, a portion of a storage device containing a file system for the workload partition, the portion forming an exported disk, the exporting causing an association between the global space and the exported disk to sever and placing the exported disk in a workload partition space associated with the workload partition; transitioning the boot process, the transitioning causing the boot process to stop using the scratch file system and start using the exported disk; and continuing the boot process using the exported disk, wherein the boot process continues using data in the exported disk.
