Types ¶
type FileWriter ¶
FileWriter implements a FileWriter over tools/fio.Runner.

DeleteDirectoryContents deletes some of the contents of random directory up to a specified depth, based on its input options:
- MaxDirDepthField
- DeletePercentOfContentsField
Default values are used for missing options. The method returns the effective options used along with the selected depth and the error if any. ErrNoOp is returned if no directory is found.
func (*FileWriter) DeleteEverything ¶
func (fw *FileWriter) DeleteEverything() error
DeleteEverything deletes all content.
func (*FileWriter) DeleteRandomSubdirectory ¶
DeleteRandomSubdirectory deletes a random directory up to a specified depth, based on its input options:
- MaxDirDepthField
Default values are used for missing options. The method returns the effective options used along with the selected depth and the error if any. ErrNoOp is returned if no directory is found.
func (*FileWriter) WriteRandomFiles ¶
WriteRandomFiles writes a number of files at some filesystem depth, based on its input options.
- MaxDirDepthField
- MaxFileSizeField
- MinFileSizeField
- MaxNumFilesPerWriteField
- MinNumFilesPerWriteField
- MaxDedupePercentField
- MinDedupePercentField
- DedupePercentStepField
Default values are used for missing options. The method returns the effective options used along with the selected depth and the error if any.
