第1题：
Companycom wants to apply a PTF to the p5 590 system. After doing a preview install, the output shows there is insufficient space in the /usr filesystem. The root volume group has no available physical partitions left. They do not want to add additional disk drives to the system, but have a jfs2 filesystem that is only 8% used. What could they do to utilize space in the jfs2 filesystem to apply this PTF?（）
第2题：
The df command indicates that a filesystem is full， however， the du command indicates that not all space is allocated. How would the system administrator isolate the discrepancy（）

An administrator needs to apply a Technology Level update. During the preview install, the output indicates that there is insufficientspace in the /usr filesystem.

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