在EC2实例上验证安装点

我在 ec2实例上安装多个EBS卷以执行一些验证和校验和检查，但问题是在安装在目标安装点上之前，我需要检查是否没有占用该安装由于我正在动态创建安装点，例如

test_lambda.py （例如）（例如）

device_prefixes = ['f','g','h','i','j','k','l','m','n','o','p']
        attached_volumes = []
        
        
        try:
            for index,volume_id in enumerate(created_volumes):
                
                MOUNT_POINT = "/dev/sd{}".format(device_prefixes[index])

我已经尝试使用 ssm Findmnt ，但它们正在显示分区和其他卷，但不像（/dev/sde，/dev/sdf etc）那样定位

原文

i am mounting multiple ebs volumes on an ec2 instance to perform some validations and check-sums but the problem is that before mounting volumes on the target mount point , i need to check whether that mount is not occupied, since i am creating mount points dynamically e.g

test_lambda.py (e.g)

device_prefixes = ['f','g','h','i','j','k','l','m','n','o','p']
        attached_volumes = []
        
        
        try:
            for index,volume_id in enumerate(created_volumes):
                
                MOUNT_POINT = "/dev/sd{}".format(device_prefixes[index])

I have tried commands using SSM like /proc/mounts, findmnt, but they are displaying partitions and other volumes but not target like (/dev/sde,/dev/sdf etc)

多亏了约旦提供的提示，我能够清除对块设备映射的理解， boto3 ec2客户端有一种相关的方法，

`# where attribute can be one of the following`  `"""'|'kernel'|'ramdisk'|'userData'|'disableApiTermination'|'instanceInitiatedShutdownBehavior'|'rootDeviceName'|'blockDeviceMapping'|'productCodes'|'sourceDestCheck'|'groupSet'|'ebsOptimized'|'sriovNetSupport'|'enaSupport'|'enclaveOptions'|'disableApiStop',z"""`
        print(instance.describe_attribute(
    instance.describe_attribute(
                Attribute='blockDeviceMapping',
                DryRun=False,
                
                )

它确实为我们提供了有关某些资源的信息，如果我的问题不清楚，则表示歉意首先，

{'BlockDeviceMappings'：[{'deviceName'：'/dev/xvda'，'ebs'：
{'factiontime'：dateTime.dateTime（2022、5、27、12、4、1，
tzinfo = tzlocal（）），'deleteonmention'：true，'状态'：'nacted'，
'volumeid'：'vol-05bb41df0e6bc4bf3'}}，{'deviceName'：'/dev/sdl'，
'ebs'：{'entacttime'：dateTime.dateTime（2022、5、27、15、15、51，
tzinfo = tzlocal（）），'deleteonmention'：false，'状态'：'nacted'，
'volumeid'：'vol-00be0e0f001fea1a9'}}}，{'deviceName'：'/dev/sdm'，
'ebs'：{'entacttime'：dateTime.dateTime（2022、5、27、15、15、51，
tzinfo = tzlocal（）），'deleteonmention'：false，'状态'：'nacted'，
'volumeid'：'vol-09c552e7777ba2a563f'}}}，{'deviceName'：'//dev/sdn'，
'ebs'：{'entacttime'：dateTime.dateTime（2022、5、27、15、15、52，
tzinfo = tzlocal（）），'deleteonmention'：false，'状态'：'nacted'，
'volumeid'：'vol-08d28a4ffe5e71dff'}}，{'deviceName'：'/dev/sdo'，
'ebs'：{'entacttime'：dateTime.dateTime（2022、5、27、15、15、53，
tzinfo = tzlocal（）），'deleteonmention'：false，'状态'：'nacted'，
'volumeid'：'vol-0e63fa17bd6185ee3'}}}，{'deviceName'：'/dev/dev/sdf'，
'ebs'：{'entacttime'：dateTime.dateTime（2022、5、27、15、36、42，
tzinfo = tzlocal（）），'deleteonmention'：false，'状态'：'nacted'，
'volumeid'：'vol-058de095fcfb1ef05'}}}，{'deviceName'：'//dev/sdg'，
'ebs'：{'atta

Thanks to the hint provided by jordan, i was able to clear my understanding about block device mapping , boto3 ec2 client has a method associated

`# where attribute can be one of the following`  `"""'|'kernel'|'ramdisk'|'userData'|'disableApiTermination'|'instanceInitiatedShutdownBehavior'|'rootDeviceName'|'blockDeviceMapping'|'productCodes'|'sourceDestCheck'|'groupSet'|'ebsOptimized'|'sriovNetSupport'|'enaSupport'|'enclaveOptions'|'disableApiStop',z"""`
        print(instance.describe_attribute(
    instance.describe_attribute(
                Attribute='blockDeviceMapping',
                DryRun=False,
                
                )

it does give us info about certain resources, apologies if my question was not clear in the first place,
