fsck
Performs file system consistency check and repairs file system errors. Only a superuser may run fsck. Run fsck after running umount, or if you encounter file write errors (for example, timeouts).

Syntax diagrams and code samples use one or more of these styles to mark placeholders for variable values. Replace placeholders with a valid option or your own user-defined value. In CQL statements, angle brackets are required to enclose data types in a set, list, map, or tuple.
Separate the data types with a comma.
For example: In Search CQL statements, angle brackets are used to identify the entity and literal value to overwrite the XML element in the schema and |

Square brackets surround optional command arguments. Do not type the square brackets. |
|
Parentheses identify a group to choose from. Do not type the parentheses. |
|
A pipe separates alternative elements. Type any one of the elements. Do not type the pipe. |
|
Indicates that you can repeat the syntax element as often as required. |
|
Single quotation marks must surround literal strings in CQL statements.
Use single quotation marks to preserve upper case.

For Search CQL only: Single quotation marks surround an entire XML schema declaration, such as |

Curly braces enclose maps ( |

Ends a CQL statement. |

Separate command line options from command arguments with two hyphens. This syntax is useful when arguments might be mistaken for command line options. |
Options
If an option has a short and long form, both forms are given, separated by a comma.
- -p, --parallelism num_files

Use throttling to minimize the performance impact of running
fsckon clusters. Specify the number of files to repair at one time.
Examples
Check file system and repair errors:
dsefs dsefs://127.0.0.1:5598/ > fsck
Use throttling to limit the number of files being repaired at the same time to 8:
dse fs fsck -p 8
