title: "Resetting a Machine"

|
From time to time, it may be beneficial to reset a Talos machine to its "original" state.
|
|
Bear in mind that this is a destructive action for the given machine.
|
|
Doing this means removing the machine from Kubernetes, Etcd (if applicable), and clears any data on the machine that would normally persist a reboot.
|
|
|
|
The API command for doing this is `talosctl reset`.
|
|
There are a couple of flags as part of this command:
|
|
|
|
```bash
|
|
Flags:
|
|
--graceful if true, attempt to cordon/drain node and leave etcd (if applicable) (default true)
|
|
--reboot if true, reboot the node after resetting instead of shutting down
|
|
```
|
|
|
|
The `graceful` flag is especially important when considering HA vs. non-HA Talos clusters.
|
|
If the machine is part of an HA cluster, a normal, graceful reset should work just fine right out of the box as long as the cluster is in a good state.
|
|
However, if this is a single node cluster being used for testing purposes, a graceful reset is not an option since Etcd cannot be "left" if there is only a single member.
|
|
In this case, reset should be used with `--graceful=false` to skip performing checks that would normally block the reset.
