# zdb(8)

ZFS debugger

## NAME

zdb - ZFS debugger

## SYNOPSIS

```
zdb pool
```

## DESCRIPTION

The **zdb** command is used by support engineers to diagnose failures and gather statistics. Since the **ZFS** file system is always consistent on disk and is self-repairing, **zdb** should only be run under the direction by a support engineer.

Any options supported by this command are internal to Sun and subject to change at any time.

## EXIT STATUS

The following exit values are returned:

**0**

The pool is consistent.

**1**

An error was detected.
