AHV创建物理扇区大小为4k的磁盘。我需要创建512字节扇区大小。使用vm.disk_create没有发现任何选项参数。还有其他方法来达到这个要求吗?

    @Prasanta库马尔此更改将影响Nutanix volume提供的所有虚拟机和卷组，在某些情况下可能导致性能下降。因此，如果不了解为什么要这样做的确切要求，就不应该这样做。此外，也可能有其他方法来解决这个问题，因为每个实例都不同。

    我能知道你为什么要把4K改成512吗?

    对您的问题的简短回答是肯定的，有一种方法可以将4k更改为512字节，但步骤是内部的。

    \u00a0@Prasanta Kumar<\/user-mention>\u00a0The change will impact all virtual machines and volume groups\u00a0served\u00a0by Nutanix Volumes and it may lead to degraded performance in some instances. Therefore, this should not be done without understanding the exact requirement of why to do.\u00a0Also, there\u00a0could be other ways to solve the issue as it varies from instance by instance.<\/p>

    \u00a0<\/p>

    So may I know why you want to change it from 4K to 512?<\/p>

    \u00a0<\/p>

    A short answer to your questions is yes, there is a way to change from 4k to 512 bytes but the steps are internal.<\/p>

    你好，尼尔，感谢你快速而简短的解释。这一需求与windows存储副本有关，这是抱怨在两个完全相同大小但在不同虚拟环境的不同系统上的两个卷之间的不同扇区大小。我同意，这不是一个好主意，改变Nutanix的音量水平，当然我不会去。我只是在检查单个磁盘层面的可能性。

    Hello Neel,, appreciate your quick and brief explanation. This requirement is\u00a0relate to windows storage replica, which is complaining about different sector size between two volume on two different systems those are exact same size but on different virtual environment. I agree, it is not a good idea to change at Nutanix volume level and certainly I will not be going for that. I was just checking for a possibility to that at individual disk level.\u00a0<\/p>","quoteUsername":"Prasanta Kumar","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    嗨 @Prasanta库马尔我不得不说，这种变化不是针对单个磁盘级别的，而是集群范围内的变化。

    Hi @Prasanta Kumar<\/user-mention>\u00a0I am afraid to say the change is not as per individual disk level but it is cluster wide change.<\/p>","quoteUsername":"Neel Kotak","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
