RAID on el capitan

Apple has removed the RAID configuration options from the GUI of Disk Utility. You will have to use "diskutil appleRAID" in Terminal.

I've seen this before. I have no experience using Terminal but can follow instructions well. Please guide me. Thanks.

SOFTRAID is now the goto option.

"SoftRAID version 5 is just $179. SoftRAID Lite is just $49."

"SoftRAID Lite is limited to creating and using stripe (RAID 0) and mirror (RAID 1) volumes."

I was using it for Mirrored data volumes in case of a hard disk drive failure.

The Terminal command would look like this:

sudo diskutil appleRAID create stripe "Volume name" JHFS+ disk1 disk2

- "stripe" will create a RAID0

- "JHFS+" will format the volume as "OS X Extended (journaled)"

- replace "disk1" and "disk2" with your own disks, to find out what numbers your disks are, use the Terminal command "diskutil list"

Great for stripes.

What about mirror volumes.

In the super user command, does replacing "stripe" with "mirror" form a RAID1 mirror between the two disks?

Does this SUDO command need to be executed every time one boots up or is it toggled on until one toggles it off?

I have used SoftRAID in the past for mirrored volumes.

I have a number of old MacPros now with multiple drives that I could use this instead.

For RAID1 use:

sudo diskutil appleRAID create mirror ...

For more options have a look at "man diskutil".

From "man sudo":

sudo allows a permitted user to execute a command as the superuser or another user...

In this case you use it to elevate your user rights and run "diskutil" with root privileges. You want to change a partition table after all.

"diskutil" is the actual tool that creates a RAID set. The RAID configuration is stored on the disks, and will stay there until you decide to re-format the drives. So no, you don't have to use that command after every reboot.
