单选题A system administrator has determined that the /development filesystem needs to be changed from JFS to JFS2 to take advantage of the new capabilites available in JFS2. What is the method to convert the /development filesystem from type JFS to JFS2？（）A
题目
Umount the /development filesystem and remount it using the following command： mount -t jfs2 /development
Edit the /etc/filesystems file to change the type paramter to jfs2 and change the log parameter to jfs2log
Backup the /development filesystem data， delete the JFS /development filesystem， create the new JFS2 /development filsystem， and restore the data to the /development filesystem
Backup the /development filesystem data， change the /development filesystem using the following command，chfs -t type=jfs2 /development.then， restore the data to the /development filesystem

第2题：
An Enhanced Journeyed File System that is in a shred non-concurrent Volume Group is growing at an unexpected rate. It is the administrator’s task to enlarge the filesystem without interrupting service. What method should be sued to achieve this goal？（）
- A、 Use HACMP C-SPOC to increase the size of the JFS2 filesystem.
- B、 Use the smitty jfs2 fastpath to increase the size of the JFS2 filesystem.
- C、 Use HACMP C-SPOC to increase the size of the JFS2 filesystem and inline JFS2 logs.
- D、 Use mklvcopy hdisk# 2 jfs2lvname to increase the size of the JFS2 filesystem，then use splitlvcopy jfs2lvname 1 -y newjfs2lvname hdisk# to present the increased JFS2 filesystem to HACMP.

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
