An administrator is writing a decommissioning script for removable media. Partition /dev/sdc1 was once initialized as an LVM physical volume but has already been removed from all volume groups. The script must wipe the LVM metadata so that the device appears as a normal block device again and must run unattended without pausing for confirmation. Which command satisfies these requirements?
The -y (or --yes) option tells pvremove to automatically answer "yes" to every confirmation prompt, enabling the command to run non-interactively inside a script. Using pvremove -y /dev/sdc1 therefore erases the LVM label on /dev/sdc1 without any manual input. The -t flag launches pvremove in test mode, so no metadata is changed; -v only increases verbosity; and --force suppresses some safety checks but can still ask for confirmation unless -y is also supplied and is unnecessary when the device is already outside every volume group.
