如何使用Python命令管理Linux存储设备

要使用Python命令管理Linux存储设备，您可以使用os和subprocess库

1. 列出所有可用的磁盘分区：

import os

def list_partitions():
    partitions = []
    for device in os.listdir('/dev'):
        if device.startswith('sd'):
            partitions.append(device)
    return partitions

print(list_partitions())

2. 检查磁盘空间使用情况：

import subprocess

def check_disk_space(device):
    result = subprocess.run(['df', '-h', device], capture_output=True, text=True)
    return result.stdout

device = '/dev/sda1'
print(check_disk_space(device))

3. 创建新目录：

import os

def create_directory(path):
    try:
        os.makedirs(path)
        print(f"Directory {path} created successfully.")
    except FileExistsError:
        print(f"Directory {path} already exists.")

path = '/mnt/new_directory'
create_directory(path)

4. 挂载磁盘分区：

import subprocess

def mount_partition(device, mount_point):
    try:
        subprocess.run(['mount', device, mount_point], check=True)
        print(f"Partition {device} mounted successfully at {mount_point}.")
    except subprocess.CalledProcessError as e:
        print(f"Error mounting partition {device}: {e}")

device = '/dev/sdb1'
mount_point = '/mnt/partition'
mount_partition(device, mount_point)

5. 卸载磁盘分区：

import subprocess

def unmount_partition(mount_point):
    try:
        subprocess.run(['umount', mount_point], check=True)
        print(f"Partition {mount_point} unmounted successfully.")
    except subprocess.CalledProcessError as e:
        print(f"Error unmounting partition {mount_point}: {e}")

mount_point = '/mnt/partition'
unmount_partition(mount_point)

请注意，这些示例可能需要根据您的Linux发行版和系统配置进行调整。在使用这些命令时，请确保您具有适当的权限。
