Abstract
Abstract A method for decreasing the size of a root partition on a computer system operating under control of a UNIX type operating system without reinstalling the operating system. The computer system includes a first storage device. The first storage device includes the root partition which has a first size. The root partition includes a root file system. The method includes backing up the root file system to a backup file system, booting the computer system to a maintenance mode, deactivating the root partition, activating the root partition at a second size smaller than the first size, and restoring the root file system from the backup file system.

Claim 8
Dependent Claim
38 words
The method of claim 6, wherein the restoring the root file system from the backup file system comprises: identifying the second root partition to the computer system; and copying the backup file system to the second root partition.
Claim 9
Dependent Claim
90 words
The method of claim 7, wherein the restoring the root file system from the backup file system further comprises: mounting a first directory to the second root partition after identifying the second root partition to the computer system; activating the backup file system after identifying the second root partition to the computer system if the backup file system is not active; and mounting a second directory to the backup root file system after activating the backup file system and before copying the backup file system to the second root partition.
Claim 10
Dependent Claim
54 words
