## NAME
|
|
podman\-system\-reset - Reset storage back to initial state
|
|
|
|
## SYNOPSIS
|
|
**podman system reset** [*options*]
|
|
|
|
## DESCRIPTION
|
|
**podman system reset** removes all pods, containers, images, networks and volumes, and machines.
|
|
It also removes the configured graphRoot and runRoot directories. Make sure these are not set to
|
|
some important directory.
|
|
|
|
This command must be run **before** changing any of the following fields in the
|
|
`containers.conf` or `storage.conf` files: `driver`, `static_dir`, `tmp_dir`
|
|
or `volume_path`.
|
|
|
|
`podman system reset` reads the current configuration and attempts to remove all
|
|
of the relevant configurations. If the administrator modified the configuration files first,
|
|
`podman system reset` might not be able to clean up the previous storage.
|
|
|
|
## OPTIONS
|
|
#### **--force**, **-f**
|
|
|
|
Do not prompt for confirmation
|
|
|
|
#### **--help**, **-h**
|
|
|
|
Print usage statement

## EXAMPLES

|
Reset all storage back to a clean initialized state.
|
|
```

### Switching rootless user from VFS driver to overlay with fuse-overlayfs
|
|
|
|
If the user ran rootless containers without having the `fuse-overlayfs` program
|
|
installed, podman defaults to the `vfs` storage in their home directory. If they
|
|
want to switch to use fuse-overlay, they must install the fuse-overlayfs
|
|
package. The user needs to reset the storage to use overlayfs by default.
|
|
Execute `podman system reset` as the user first to remove the VFS storage. Now
|
|
the user can edit the `/etc/containers/storage.conf` to make any changes if
|
|
necessary. If the system's default was already `overlay`, then no changes are
|
|
necessary to switch to fuse-overlayfs. Podman looks for the existence of
|
|
fuse-overlayfs to use it when set in the `overlay` driver, only falling back to vfs
|
|
if the program does not exist. Users can run `podman info` to ensure Podman is
|
|
using fuse-overlayfs and the overlay driver.
