第1题：

The system administrator notices that there is an I/O bottleneck on one of three disks in datavg volume group. This problem disk contains the JFS log， loglv00 and one filesystem， /mydatabase.  There are no other logical volumes on this disk.  Which of the following options would be the best solution？（）

  • A、 Increase the size of the JFS log logical volume so more transacations can be written to this log.
  • B、 Create a second， additional JFS log and have the /mydatabase logical volume point to both JFS logs.
  • C、 Migrate the JFS log device to another physical disk in the same volume group.
  • D、 Only one JFS log device for each volume group can be used.  Use the migratepv command to move the JFS log device to an empty disk in another volume group.
