# Command: node drain
|
|
|
|
The `node drain` command is used to toggle drain mode on a given node. Drain
|
|
mode prevents any new tasks from being allocated to the node, and begins
|
|
migrating all existing allocations away.
|
|
|
|
The [node status](/docs/commands/node/status.html) command compliments this
|
|
nicely by providing the current drain status of a given node.
|
|
|
|
## Usage
|
|
|
|
```
|
|
nomad node drain [options] <node>
|
|
```
|
|
|
|
A `-self` flag can be used to drain the local node. If this is not supplied, a
|
|
node ID or prefix must be provided. If there is an exact match, the drain mode
|
|
will be adjusted for that node. Otherwise, a list of matching nodes and
|
|
information will be displayed.
|
|
|
|
It is also required to pass one of `-enable` or `-disable`, depending on which
|
|
operation is desired.
|
|
|
