When installing a VSAN node system, you need to be careful that there is no partition information for either the cache disk or the capacity disk. So every time you install the system and configure the network, log in to the node web before joining the cluster to see if the disk has partition information, and if so, delete it as shown below. If you have joined the cluster, it is not easy to delete partition information. (summary of best practices)

Method 1:

After practice, it is concluded that the patella is not very reliable, even if the partition can not be seen, if there is an error in the implementation of clear, there may be problems.

Method 2:

Log in to shell and use command. As long as a disk like naa.500xxxx cannot see the partition information, there will be no partition.

The method of clearing the partition corresponding to this method:

[root@vsannode:/dev/disks] partedUtil delete naa.5000c500a05432e7 1

Method 3:

Add the node to the vsan, and check the disk management of the vsan cluster. If the number of disks you see is qualified, it means that no disk has a partition problem.
