With that said, you still have to be careful about using too little physical disk space or too many storage spaces because if the storage space really does run out of physical disk space in the pool, it'll immediately unmount, and if you had some type of file I/O operation going on at the time, like a save or a copy, it'll be immediately cut off, and you will end up with data corruption. If this happens, you can remount the storage space manually and you can still access your files in the storage space. However, you won't be able to do much with the storage space until you add morephysical disk space to the pool and allocate it to that storage space. Summary 9:12-9:25 In this lesson, we talked about Storage Spaces. We talked about how Storage Spaces manages storage spaces. We also identified the three key components in a storage space, and then, we talked about thin provisioning, which allows us to allocate more space than we actually have physical disk space for. Creating Storage Spaces 0:00-0:57 In this demonstration, we're going to spend some time working with storage spaces on this Windows 10 system. So in order to this, I first need to make sure that I have extra hard drives installed in the system that I can use for storage spaces. So I'm going to open up Disk Management, and here you can see that I have my Windows operating system installed on Disc zero and it uses up the entiredisk. However, I also have several other blank hard disk drives in the system that currently aren't allocated to anything. They have no partitions, no volumes defined on them. I have Disk 1, 2, 3, 4, and Disk 5. And they're all about 32 gigs in size. So with these storage devices installed, I can go ahead and define storage spaces. I'm going to right click on my Windows icon and then open up Control Panel. And then within Control Panel, I need to go to System and Security and then click on Storage Spaces.

The first thing I need to do before I can create a storage space is to define a new storage pool. A storage pool is composed of multiple storage devices in the system. Let's click on Create a New Pool in Storage Space and we do have to elevate privileges to do this. Now I'm presented with a list of currently unformatted drives in the system that I could potentially add to the storage pool. One option would be to add all of these disks all at the same time to the pool. But for demonstration purposes, I'm actually only going to add Disk 1, 2, and 3 to the pool at this time. Click Create Pool. So at this point, I have a storage pool defined, but before I can actually use that pool to save files, I need to define a storage space within that pool. Creating a Storage Space 1:40-8:30 Now a storage space functions in some ways like a traditional volume. If you have a blank hard disk drive and you want to create a volume on it, you can have that volume encompass the entire hard disk drive. Or you can divide one disk into multiple volumes. You can do the same thing with storage spaces. You can create one storage space out of the pool or you can create lots of storage spaceswithin the same pool. Let's begin by just

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
