How to revert Mirrored Storage back to 3, 2TB hard drives?

Is there a way for me to revert my storage spaces back to the three individual hard drives I had before, without deleting the information that is already there? Right now I have a two way mirror set-up, but would really just like one big drive for backing up other computers I have on the network. Any ideas are appreciated. Also is there a way when using launchpad to bring up the "Start" window when doing a remote session, thanks.

A three drive mirror?

 

I'm guessing that, since it's Storage Spaces, you can set up mirroring across any number of drives. I would think you do it by volume size, not physical drives.

What i did initially was choose the 3 drives (no data yet) and did a two-way mirror, then loaded up my date. My problem is that the 6TB becomes 3 because of the mirror process. What I really need is the 6 TB as one drive.

If you used Storage Spaces, the only way this could happen is if SS created 2x3TB volumes from the 6TB of space and mirrored them. If you undo it then, as ITTOG says, you will have a 6TB striped volume. A striped volume has no redundancy. You might want to think about what you're going to do about backup.

 

Now, since it is a mirrored volume, you should be able to just break the mirror and then extend one of the volume drives onto the former mirrored volume. I would not do this, however, without having a proven-good backup of everything on the mirror.

In Server Manager you can go to the Storage Pools screen and in the Virtual Disks window you'll see the 2-Way Mirror you created earlier -- create another Virtual Disk but make it a "Simple" disk like you want in the same pool as what your 2-way mirror is in -- Move your files over from your 2-way Mirror to the Simple -- then either blow away the Mirror or keep it for resiliency down the road.

 

Before doing anything -- be sure any important files are backed-up (just in case). This should work though unless you had allocate your entire pool to the 2-Way Mirror earlier and can't reduce that.

If the entire Pool was allocated to the 2-Way Mirror then you may try removing 1 drive which will set off alarms for the 1st Pool but the 2-way Mirror(ed) data will still be there and use that 1 drive to start a new Pool for your Simple Storage Space and start moving your files to it. Hopefully, you have less than 2TB of Data to move in that case.

 

YMMV.

This is what I was referring to -- In my S2012E machine I have a Pool of 5 3TB drives with my Share Folders on a 2-Way Mirror Storage Spaces -- Drive D: -- I added another Storage Space this time a Simple Space -- Drive E: (Rover) based on my Pool

And there you go -- since you already have your pool -- just create another disk then create your volume.

The performance of a Simple Disk carved out of your Storage Spaces Storage Pool is simply phenominal IMHO.

This is the actual performance of the Simple Disk ROVER that I created earlier that is operating in a HP MicroServer N40L -- imagine what this could do in a regular high performance machine!

 

I expect you will see some pretty good performance with your Simple Disk carved out of your 3 2TB drive Pool also. Good luck.

 

This is way Cool! IMHO!

JM, is there no way to simply break the mirror through the Storage Pools screen, without having to physically pull a drive? That seems almost prehistoric.
