长话短说，我们在RAID5 iSCSI目标上出现驱动器故障。 我们更换了驱动器，并成功重build。 不幸的是，在这之后，ESXi丢失了数据存储。 它仍然显示在iSCSI软件适配器中，但没有关联数据存储。 我到处搜寻，试图解决这个问题。
从ESXi控制台：

它说这是VMFS，所以分区不会丢失。 当我尝试删除并重新添加iSCSI时，以下内容将被logging到/ var / log / messages中：

这似乎是我检测到的iSCSI数据存储，但它不起作用？ 我不确定。
我甚至试图自己连接到iSCSI，并使用Ubuntu中提供的VMFS工具尝试查看数据，但是每当我尝试提取信息或列表文件时，它总是会崩溃。 我甚至用VMFS Java应用程序尝试过，但也失败了。 也许VMFS已损坏？ 我找不到在设备上尝试修复的方法，因为VMware提供的工具似乎只能在卷上工作（并且不会显示为VMFS卷）。
LUN添加时确实显示，但表示要格式化和删除。
我认为你有一个与LUN的权利问题，检查它仍然是RW首先确定。
