AHV创建具有4K物理扇区大小的磁盘。我需要创建512 bytes扇区的大小。通过vm.disk_create查找没有选项参数。还有其他方法可以实现这种重新审查。

    @Prasanta Kumar这种变化将影响Nutanix卷提供的所有虚拟机和量组，并在某些情况下可能导致性能降低。因此，如果不理解为什么要这样做的确切要求，就不应做到这一点。同样，可能还有其他方法可以解决该问题，因为它因实例而异。

    所以我可以知道为什么要将其从4K更改为512？

    对您的问题的一个简短答案是，有一种方法可以从4K到512个字节，但这些步骤是内部的。

    \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>

    您好Neel，感谢您的快速和简短的解释。该要求与Windows存储复制品有关，该复制品在两个不同系统上的两个卷之间抱怨不同的扇区大小，这些副本的大小完全相同，但在不同的虚拟环境上。我同意，在Nutanix量级别上进行更改不是一个好主意，当然我不会为此而做。我只是在检查单个磁盘级别的可能性。

    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"}}}">

    你好 @Prasanta Kumar我害怕说，这种变化不是按单个磁盘级别级别的，而是群集的变化。

    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"}}}">
