From IBM AIX documentation, it is clear that all mount point information is supposed to be present in the '/etc/filesystems' file located on the system. 
When mount information is not present in '/etc/filesystems' file it can lead to abnormalities.

从IBM AIX文档中可以清楚地看到，所有挂载点信息都应该出现在系统上的'/etc/filesystems'文件中。
如果挂载信息没有出现在'/etc/filesystems'文件中，可能会导致异常。
