The system administrator wants to use a new jfslog /dev/fs1log with the filesystem /test/fs1 on the testvg volume group. The following commands were used to create the log and assign it to the filesystem：
（1）mklv -t jfslog -y /dev/fs1log testvg 1
（2）chfs -a log=/dev/fs1log /test/fs1
While trying to mount the /test/fs1 filesystem the administrator received the error：
"Cannot mount /dev/fs1lv on /test/fs1： A system call received a parameter that is not valid".
What step did the administrator miss that most likely caused the error？（）
