I can't figure out how to create a cluster ball on windows server 2012r2?

Question

System administration

Good night, I have 4 virtual machines installed on Hyper V. The task is to make the domain controller drive all the machines into one domain, make a backup and also make a cluster disk on it. Make 2 nodes on which to install the Sql cluster. The question is that I installed the cluster, created the ball. But I can't figure out how to make "cluster shared storage". I read a lot of manuals, and when I create a pool and add a disk there, it simply does not exist.

Answer 1

There is such crap with a lot of spaces. If you look through Get-PhysicalDisk, there is a CannotPoolReason property - this is the reason why you cannot use the disk under the storage pool. For the most part, on virtual machines, this will be Insufficient Capacity. As a result, as practice has shown, the size of the disk that you are trying to slip is important here. In the documentation, from everything I could find, there is a mention of a 4GB mine disk. But there is another interesting point - you specify the size in HyperV in GiB, which is not equal to GB. And as it turns out, storage spaces are very sensitive to this at the time of creation. Those. you need to convert the size to GB. For example, for 6GB disks, you need to create a 6.44245 GiB disk. And this disc will do.
The most funny thing is that if you created a pool, then you can throw it there without bothering, indicating all the same 6 GiB that are familiar to the eye.

Answer 2

To assemble a cluster, you need a shared storage with a cluster file system (in the windows world, this is CSV) On Hyper-V, you can raise a guest cluster based on shared vhdx (shared virtual disks)

Answer 3

To create a cluster shared storage (CSV) you need 3 physical machines, clustered and give them a single access to the storage system. You can use SAS, FC, iscsi - that's what you have. Then you can use a shared volume between these three machines. I must say right away that a clustered FS can only store images of virtual machines, an MSSQL database, and an Exchange database. There is a second option that the Enterpase edition since 2016 (sort of) can s2d, where you can combine physical disks of cluster machines (nodes) through storage space. But the cost of editing makes you think a lot.
