## config disk format

- Reboots the system into safe mode
- Formats all disks (the status of this process can be monitored by SSH tunnelling into the system and running `cat /mnt/store0/log/boot.cur`)
- Reboots the system back into normal mode

Depending on the size of the disks, this sequence can take between 5 to 30 minutes to complete altogether.

```fmadiocli
config disk format
```

Example output:

```bash

## config disk replace

This performs the same operation as [config disk sanitize](/v1/docs/fmadiocli-config-disk#config-disk-sanitize) does, except only on a single disk. It then immediately follows up by running one of the following:

- [config disk lock](/v1/docs/fmadiocli-config-disk#config-disk-lock)
- [config disk no-lock](/v1/docs/fmadiocli-config-disk#config-disk-nolock)

…depending on whether the other disks in the relevant array have locking enabled or disabled. If the disk in question is the only one in the array, it will be left unlocked.

As the name suggests, this command is intended to be used for when a disk in an array fails and needs to be replaced and brought back into line with its siblings.

```fmadiocli
config disk replace <identifier> <new serial number>
```
