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

Invalid file system size in the secondary superblock. Primary superblock is corrupt. Secondary superblock is corrupt. fsck： 0507-018 Superblock is corrupt and cannot be repaired.
