无法增加虚拟磁盘的大小

扩展虚拟磁盘 (VMDK) 失败

您会看到以下错误：

磁盘扩展操作失败: 原因 (The disk extend operation failed: REASON)

其中原因可以是以下任一项：

msg.disklib.NOSPACE

msg.fileio.lock

msg.disklib.UNSUPPORTEDFEATURE

msg.disklib.INVAL

22（参数无效）

5（输入/输出错误）

12（无法分配内存）

Cause

出现此问题的原因如下：

msg.disklib.NOSPACE

msg.fileio.lock

msg.disklib.UNSUPPORTEDFEATURE

msg.disklib.INVAL

22（参数无效）

5（输入/输出错误）

12（无法分配内存）

Resolution

下表列出了问题、问题原因及其相应的解决方案：

错误

错误原因

解决方案

msg.disklib.NOSPACE

如果虚拟磁盘所在数据存储没有足够的可用空间来适应虚拟机大小的增加，则会出现此问题。

要解决此问题，请通过迁移或删除不必要的虚拟机和文件来增加数据存储中的可用空间，或增加数据存储的大小。
如果数据存储是 VMFS 卷，请参见 Troubleshooting a datastore or VMFS volume that is full or near capacity (1003412)。

msg.fileio.lock

如果虚拟磁盘正在使用中，并由某些 ESXi 主机锁定，则会出现此问题。在某些情况下，即使关闭虚拟机的电源，这些锁定也不会解除。

为了防止并行更改关键虚拟机文件和文件系统，ESXi/ESX 主机对这些文件（包括虚拟磁盘）建立了锁定。
要解决此问题，请参见 Investigating virtual machine file locks on ESXi (10051)。

msg.disklib.UNSUPPORTEDFEATURE

如果虚拟磁盘描述符文件中的 ParentCID 参数未设置为 ffffffff，则会出现此问题。

要解决此问题，请参见 Extending a virtual disk fails with the error:msg.disklib.UNSUPPORTEDFEATURE (2109730)。

msg.disklib.INVAL or 22 (Invalid argument)

如果为扩展操作传递的参数无效，则会出现此问题。导致此问题的原因有多种：

虚拟磁盘不允许扩展选项。例如，不允许增加稀疏磁盘的大小。

虚拟磁盘的新大小小于现有大小。

ESXi 无法确定虚拟机所在数据存储的可用空间。

尝试在打开电源的虚拟机上扩展超过 2 TB 的 VMDK。有关详细信息，请参见 Support for virtual machine disks larger than 2 TB in VMware ESXi 5.5.x and 6.0.x (2058287)。

如果此处未列出您的失败原因，请提出支持请求。有关如何提出支持请求的详细信息，请参见 How to file a Support Request in Customer Connect (2006985)。

5（输入/输出错误）

如果 ESXi 主机访问底层存储设备或数据存储时存在问题，则会出现此问题。

对底层存储设备的任何问题进行故障排除并解决问题：

Troubleshooting LUN connectivity issues on ESXi/ESX hosts (1003955)

Troubleshooting fibre channel storage connectivity (1003680)

Troubleshooting iSCSI LUN connectivity issues on ESX/ESXi hosts (1003681)

Troubleshooting ESXi/ESX connectivity to iSCSI arrays using software initiators (1003952)

Troubleshooting connectivity issues to an NFS datastore on ESX and ESXi hosts (1003967)

12（无法分配内存）

如果 ESXi 存储堆栈中的任何软件组件（如 VMFS 模块）耗尽堆内存容量，则会出现此问题。
如果虚拟机所在的数据存储中存在大量失效的快照文件，也会出现此问题。

如果此问题是由于 VMFS 堆耗尽导致的，请参见 ESXi/ESX host reports VMFS heap warnings when hosting virtual machines that collectively use 4 TB or 20 TB of virtual disk storage (1004424)。
如果此问题是由于失效快照文件导致的，请参见 Committing snapshots when there are no snapshot entries in the Snapshot Manager (1002310)。
如果此问题是由于其他原因导致的，请提出支持请求。有关详细信息，请参见 How to file a Support Request in Customer Connect (2006985)。

注意：如果您看到其他故障原因，请向 VMware 支持提交支持请求。有关详细信息，请参见 How to file a Support Request in Customer Connect (2006985)。
