第1题：

An administrator has just imported a shred Volume Group that had been created on another  system in the cluster. In order for the shred volume to be used in the cluster， what is the most important step for the administrator to take first？（）   

• A、 Change the quorum required to false.
• B、 Change the Volume Group auto vary on to yes， and then vary off the Volume Group.
• C、 Change the auto vary on value of the Volume Group to no， and then vary off the volume group.
• D、 Set the Volume Group major number to the same value that the Volume Group had on the system on which it was created.

第2题：

A system administrator has a filesystem called /test/data in volume group datavg. Which of the following commands will allow the administrator to create a mirrored copy of the filesystem’s data？（）

• A、chfs
• B、chlv
• C、mklvcopy
• D、mkfscopy

第3题：

The /systest filesystem is associated with the /dev/testlv logical volume on the ’testvg’ volume group. Given this information， which of the following commands can the system administrator use to determine if the /systest filesystem is mirrored？（）

• A、df
• B、lsvg
• C、lsfs
• D、lsdev

第4题：

A system administrator can create logical volumes and then add file systems to them， or create the file system directly. What is an advantage of the two-step approach instead of the one-step approach？（）

• A、The number of bytes per inode can be specified.
• B、Placement of the filesystem on the disk can be specified.
• C、The jfslog can be specified on creation of the filesystem.
• D、Either a JFS or JFS2 filesystem can be created on the logical volume.

第5题：

While attempting to expand a file system, an administrator receives an error message indicating that the filesystem is not recognized. Running the 'lsfs' command fails to display any output, but the 'df' command is working and displays normal filesystems. What is the likely cause of the problem?（）

• A、The /etc/filesystems file is missing.
• B、The /dev/hd8 logical volume is corrupt.
• C、The hosting volume group is not varied on.
• D、The /var and /tmp filesystems may be full.

第6题：

An administrator is attempting to recover a filesystem that fails to manually unmount. The fsck command produces the following output： The current volume is： /dev/fslv02 File system is currently mounted.   Invalid file system size in the primary superblock. 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. Both primary and secondary copies are corrupt.Cannot continue tried to mount  Which steps will resolve the problem？（）

• A、Reboot the server into maintenance mode and run ‘fsck’ with the ‘-p’ parameter while the filesystem is mounted.
• B、Reboot the server into maintenance mode and run ‘fsck’ with the ‘-y’ parameter while the filesystem is unmounted.
• C、Force a umount of the filesystem with ‘umount -F /dev/fslv02’， and then run ‘fsck -p /dev/fslv02’ while the filesystem is unmounted.
• D、Force a umount of the filesystem by varying off the hosting volume group and then varyon the volume group. This will permit ‘fsck -y’ to be run against the failing filesystem.

• 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.

第10题：

An administrator is attempting to recover afilesystem that fails to manually unmount. The fsck command produces the following output: The current volume is: /dev/fslv02 File system is currently mounted. Invalid file system size in the primary superblock. Invalid file system size in the secondary superblock. Primary superblock is corrupt. Secondary superblock is corrupt. fsck: Cannot continue tried to mount Which steps will resolve the problem?（）

• A、Reboot the server into maintenance mode and run 'fsck' with the '-p' parameter while the filesystem is mounted
• B、Reboot the server into maintenance mode and run 'fsck' with the '-y' parameter whilethe filesystem is unmounted
• C、Force a umount of the filesystem with 'umount -F /dev/fslv02', and then run 'fsck p /dev/fslv02' while the file system is unmounted
• D、Force a umount of the filesystem by varying off the hosting volume group and then varyon the volume group. This will permit 'fsck -y' to be run against the failing filesystem
