+ A function to run crefi on a given mount point and generate I/O.
+
+ Args:
+ client(str): Client on which I/O has to be performed.
+ mountpoint(str): Mount point where the client is mounted.
+ number(int): Number of files to be created.
+ breadth(int): Number of directories in one level.
+ depth(int): Number of levels of directories.
+
+ Kwargs:
+ thread(int): Number of threads used to generate fop.
+ random_size(bool): Random size of the file between min and max.
+ fop(str): fop can be [create|rename|chmod|chown|chgrp|symlink|hardlink|
+ truncate|setxattr] this specifies the type of fop to be
+ executed by default it is create.
+ filetype(str): filetype can be [text|sparse|binary|tar] this specifies
+ the type of file by default it is text.
+ minfs(int): If random is set to true then this value has to be altered
+ to change minimum file size. (Value is in KB)
+ maxfs(int): If random is set to true then this value has to be altered
+ to change maximum file size. (Value is in KB)
+ single(bool): Create files in a single directory.
+ multi(bool): Create files in sub-dir and sub-sub dir.
+ size(int): Size of the files to be created. (Value is in KB)
+ interval(int): Print number files created of interval.
+ nameBytes(int): Number of bytes for filename. (Value is in Bytes)
+ random_filename(bool): It creates files with random names, if set to
+ False it creates files with file name file1,
+ file2 and so on.
+
+ Returns:
+ bool: True if I/O was sucessfully otherwise False.
+
+ NOTE:
+ To use this function it is a prerequisite to have crefi installed
+ on all the clients. Please use the below command to install it:
