编辑我不明白为什么这被标记为重复,因为标识的重复需要导入pyudev。甚至不可能是复制品。在
这很管用,但感觉“蛮力”。在
有没有一种更像python的方法来获取Linux上可用磁盘设备名的列表。在
def get_list_of_available_disk_device_names():
# device names are prefixed with xvd
# any alpha characters after the prefix identify the specific device,
# it is possible that there are numbers after the fourth character
# https://rwmj.wordpress.com/2011/01/09/how-are-linux-drives-named-beyond-drive-26-devsdz/
# in this case we are hard coding the limit to an arbitrary 26 so device names do not go beyond z
# the device name prefix can vary across operating systems. 'xvd' is Xen devices on Linux
device_name_prefix = 'xvd'
device_letters = [x[3] for x in os.listdir('/dev') if x.startswith(device_name_prefix) and x[3] in string.lowercase]
device_letter_alpha_numbers = [string.lowercase.index(device_letter) for device_letter in device_letters]
next_available_device_number = max(device_letter_alpha_numbers) + 1
if next_available_device_number > 25: # a is 0, z is 25
raise Exception('No more devices available')
return ['xvd{}'.format(string.lowercase[x]) for x in range(next_available_device_number, 25)]
使用:
^{pr2}$
我想这可以适应。在
