Abstract:
A computer implemented method, apparatus, and computer usable program code for preserving a virtual file system. Data for a virtual file system is received. The data include file handle information, vnode information, and gnode information. The data is saved to a storage device. The saved data can be used to reconstruct the virtual file system upon changeover between a primary data processing system and a backup data processing system.
