How To Setup Raid 5 On Windows Server 2012 R2
Setting upward RAID 5 on Server 2012 r2
I take a Dell R230 WS 2012 r2 with iv physical disks. Here is my layout. RAID is non set nevertheless. I have to swap out Deejay 2 and three with 2 x 2TB disks. My question is once I shut the server down and swap the physical disks with the new disk and kicking support will my PERC H330 exist able to handle converting both disks along with Deejay 3 to RAID 5 at the same time? And also how long do you call back information technology will take to build the disks?
Disk 0 Bone
Disk i
Disk 2
Disk three File data

Are you using spinning rust or SSD?
It is not recommended to use spinning rust for RAID v, merely using SSD is perfectly fine.

At 2TB drives, four of them and a inexpensive H330 controller and quondam Windows, prophylactic to assume this is spinning rust and therefore... no RAID 5. With four drives, RAID x is the simply rational option.

RAID arrays don't continue data in one identify or another. Your OS and files volition be on the same array. Once you make your array, one all the existing information is gone, and two the Bone will see but a single drive.

i would never experiment with raid on a live datadisk :) for starters.
back up your data (don't know how much it is) , once the data is backed up create a raid 5 volume of the datadisk and the 2 empty ones
creating an empty array is very quick , restore data and your good to go.
brand sure you have a decent backup in place , raid 5 is redundant but not the top solution.I've had some friends who extended / created their raid sets without backups and ended up with a big empty volume ... you lot don't want that :)

Do you have four disks in the server currently? Are they in RAID at present? If so, which level?
You cannot replace 2 drives in a RAID 5 at the same time.
If you don't have RAID now, you need to backup and restore the data in one case the RAID is created.
Yous are ameliorate off going to a 4 bulldoze RAID ten.

yous demand to back up ALL your data outset, as RAID prepare up volition need empty drives
why R5 though, at that place is a valid reason to use it, just as far every bit I can recall it Volition have issues sooner rather so afterward equally the maths behind the larger >TB drives, is going to give you lot problems so far equally longevity goes
why not get an additional bulldoze, and get R6 ? better redundancy and still has decent R/W speeds

You can't just add a drive into a RAID assortment. You demand to fill-in, create the array, then restore to the assortment.

RAID takes all of the drives and makes one array and in doing so you will lose whatsoever information stored on them.
To create a new RAID array you demand to practise a backup of the data first.

All it does is tell u.s.a. that the install is screwed upwardly and you demand to outset over.
- Under no condititions should y'all non exist virtualized.
- Under no conditions should you not accept RAID on all the disks
- Under no conditions should anything but RAID 10 exist used with four disks
- Nether about no conditions should your hypervisor, OS and information be on dissimilar disks
You need all four of these things fixed before yous talk most anything else. These are "must do" items. Don't use this in production until all four are addressed. None are in any way adequate to skip. IF you add together more disks, and then you tin can talk about non-RAID 10 options.

You are 100% certain y'all can't get another 2TB bulldoze?
The only halfway decent solution I tin think of isn't very good. Create a RAID1 of deejay 0 and ane. It will waste half of the infinite on disk ane, only it will work. Create another RAID1 of disk 2 and iii.
That volition give you RAID arrays, then y'all've got some redundancy in case of bulldoze failure. Everything else we said applies - backup, backup, test! Create arrays. Install a hypervisor and install your OS in a VM.
As soon as possible go another 2TB drive and then you lot tin can wipe this out and start fresh with RAID10.

If you lot are unable (or unwilling) to start from scratch then yous might be stuck with what y'all take.
Y'all will need matching drives to do the RAID 10, without that pace you are stuck. Seems like a small price to pay to become the server setup correctly.

What are my benefits of going with RAID 10 over RAID five?
1) IOPS - yous're using 4 disks instead of 3 and you are not using parity
2) security - RAID 5 rebuilds on large arrays are very deadening and if there is a trouble during that slow rebuild the entire assortment may exist lost.

And then basically speed and some reliability during the rebuild is the benefit.
On the downside I would have our main file server downwardly for 10 amount of time which it rebuilds and from what I take seen I would accept to reload the Bone. Correct?

"some" is an understatement. If you lose a drive in RAID five the chances of losing everything are much higher than if you have RAID 10. With 2TB drives I would say y'all'd be safer by not using RAID 5 at all and simply using single disks for your data.
On the downside I would have our main file server down for X amount of time which information technology rebuilds and from what I have seen I would have to reload the Bone. Correct?
To properly setup your Server you need to do this anyway.
To be clear, there is no 'rebuilding' when creating a new array. Creating an array only take a few minutes. Or do y'all hateful fixing things, then you are using a hypervisor and VMs? Aye, that volition have a while to get properly setup.

No I am non using VM's or a Hypervisor.
Then If I get the tertiary 2TB disk my steps are to swap out Deejay, 0, 1 and two, re-install the Os, fix RAID 10, and restore the file server from backup? That would give me an 8TB file server correct?

No I am not using VM's or a Hypervisor.
So If I go the 3rd 2TB disk my steps are to swap out Disk, 0, 1 and 2, re-install the OS, ready RAID 10, and restore the file server from fill-in? That would give me an 8TB file server correct?
Y'all should use a Hypervisor and VM, there is no downside to this only upside.
You will not reinstall the OS, you will install a hypervisor and setup a virtual server on top of it. It will take virtually the same amount of fourth dimension. Hell, you can do a P2V of your current server and be upward and running really quick.

I know you aren't now. I was saying that information technology will accept a piddling time to get them setup, especially because information technology's new to you.
Swap out disks, setup RAID. RAID is always commencement because you lot tin can't employ the storage until the RAID is configured.
iv 2TB drives in a RAID10 gives you lot 4TB of space.

Yous have to setup the RAID during boot, because setting up RAID 10 volition destroy information on your OS drive, since you will adding that bulldoze to the RAID. I would call in some outside expertise. In that location are lots of ways this can plow into a very bad twenty-four hour period.
