An administrator needs to apply a Technology Level update. During the preview install, the output
indicates that there is insufficientspace in the /usr filesystem. Review of the root volume group
indicates there are no available physical partitions, but the /test jfs2 filesystem is only 8% used.
What is the most efficient method to use the available space in the /test filesystem to apply
theupdate?

A.
Use chfs to reduce the /test filesystem

B.
Use cplv to copy the /test filesystem to a smaller logical volume

C.
Use migratepv l to move the /test filesystem to a different volume group

D.
Backup the /test filesystem, remove it, and recreate it with a smaller size
