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.
