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 filesystemB.Use cplv to copy the /test filesystem to a smaller logical volumeC.Use migratepv l to move the /test filesystem to a different volume groupD.Backup the /test filesystem, remove it, and recreate it with a smaller size
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?（）A、Backup the filesystem and recreate smallerB、Use the chfs to reduce the filesystem sizeC、Use cplv to copy filesystem to smaller sizeD、Use migratepv to copy filesystem to smaller size
