Description

DF#getFileSystem returns null if DF#getMount is not called before. This is because DF#getFileSystem is not parsing the df command output.
This causes NameNodeResourceChecker to print the log as follows if the available space on the volume used for saving fsimage is less than the specified value (100MB by default).

Space available on volume 'null' is 92274688, which is below the configured reserved amount 104857600
