  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Hey guys!

I've searched around but not found a satisfying answer. I'm running the boot drive from an optical bay. I want to set up a 4 drive 1+0 raid from the four bays. What would be the proper way to set this up? I am on El Capitan.

Thanks,
Ty Maier
 
from what research I've done for raid's / nas. Apple no longer support being able to make a raid within disk utility. Your other options could a be physical raid card or use software based raid like soft raid (link below)

anyone else feel free to chime in, by no means I'm no storage solution specialist, this is just from what I know from my own knowledge and research.

Yep, Apple in it's infinite wisdom did drop software RAID capabilities from the Yosemite OS. But, it will still read the RAID from previous OS builds. So, if you have a pre-Yosemite OS, you can format the RAID and then you can use it on Yosemite.
 
Thanks for the help everyone! I have an iMac that still runs Mavericks. I dropped the drives in an enclosure to raid them but I only see options to build a Raid 0 or a 1. Will it be reliable if I create two Raid 0 sets and then stripe those sets afterwards?
 
Are you guys sure?

I created a RAID 0 in Disk Utility in MacOS Sierra just a few days ago. Maybe they re-introduced it?

It was under the menu 'File'-->'RAID Assistant' (in Disk Utility).
 
can confirm EL Cap does not let you set up raids via disk utility.

IF sierra has it, a breath of hope is still there

Yes, it is not available in El Capitan. Good to hear RAID utility is back now...

It is available in El Capitan through the Terminal. Not sure of the commands, but you can Google it. The feature is being added back into the Disk Utility GUI in Sierra.

Stating the obvious. OSX is based on BSD Unix, so of coarse you can whip something up with Terminal commands. But how many will actually format RAID with the Terminal? My guess is zero...
 
It's not the difficult. It's actually pretty easy to use Terminal. To some that aren't familiar with Unix or Terminal in OS X they may not be aware (meaning it's not obvious to everyone) that you can create the software RAID in Terminal. So stating that it was dropped from the OS gives them the wrong impression that it's impossible. Point is, Apple didn't really drop software RAID from the OS, they just removed the ability to do it in the Disk Utility GUI.

Yes, that is EXACTLY what I said, when I had mentioned, that anyone can continue to use softRAID created in an earlier OS X iteration. When did anyone say OS X stopped supporting softRAID? GUI support had stopped, softRaid, never did.
And yes, it is not difficult to create a softRaid partition, provided you know how to do it through the terminal commands. Creating a partition or RAID must be done precisely and the user must be well versed in various partition maps, cluster sizing and RAID types. The whole point of using OS X is, that the majority of operations are done though GUI. Otherwise you might as well jump to Linux. And even there partitions now are mostly done with help of the GUI interface...
 
I've been looking into SoftRaid--seems the way to go if you're thinking about software raids

Actually that's not what you said. So you can remember more clearly:

To recap, what you said was that the ability to create a software RAID was not included in Yosemite or El Capitan. What you said is that you could read software RAID in Yosemite and El Capitan, not that you could create them in Yosemite and El Capitan. Technically, you can create software RAID in Yosemite and El Capitan. That's what I was saying.

If you look at the links I posted you'll see that Apple makes it easier than you describe through Terminal. There's really no more options or settings than would be selected in the Disk Utility GUI. All you have to do is select the RAID type, format, name, and correct disks to include. Using the step-by-step guides I linked to, as well as numerous other guides on the net, it's very simple.

The answer to all this is the GUI interface was removed, not the ability to read or create softRaid. As I mentioned, by stating, that you can format the drive through the Terminal is stating the obvious. All OSes including any Linux and Windows iterations can do just that. Incidentally, some Linux drive formatting can require 8 or more swap partitions. I doubt very much anyone would try to do that by hand, even though, yes, it's possible to do. The fundamental part of the OSX disk partitioning and formatting was never questioned, hence my note about being able to continue to use of pre-formatted partitions from earlier OS X incarnations. What is so difficult to understand?

Yes, the functionality was removed, and pre-formatted Raid's work, but you can use the Yosemite disk utility hack to continue making software Raid's in El Capitain, see my previous post.

It's like we're all talking past each other. The OP asked the question and it was answered. Yes, GUI was removed, but not the functionality and now it's back. Can we move on now?

It's not obvious to everyone. Steve Grevis in this thread suggested that the only solution was to use hardware RAID or software RAID using 3rd party software SoftRAID. Ty Maier, who is the OP, didn't know either. You yourself even suggested it would require pre-Yosemite OS X with no mention of "hey you can do it in Terminal", even though the OP stated he's using El Capitan. There was no mention of using Terminal until I said it was possible. So I was not stating the obvious. Maybe obvious to you, but not necessarily to everyone else, since there was clearly people participating in this thread that were unaware of the ability to still create a software RAID with Terminal command in Yosemite and El Capitan.

Not everyone is familiar with what terminal commands are possible in Unix, Linux, or OS X. And this isn't Linux or Unix. This is OS X, and yes it's based on Unix, but the fact that Linux requires more commands has no bearing here. It just confuses the discussion for people who don't know how easy it is to do in OS X with a different command (appleRAID) that isn't even in Linux.

There is no difficulty in understanding anything. You said "stating the obvious" which is wrong. You also said "Yes, that is EXACTLY what I said..." which is wrong because what I said and what you said were 2 completely different things. The OP wanted to create a software RAID. Telling him that he can still read a pre-formatted RAID in El Capitan that was made pre-Yosemite wasn't helping him. He needed to create the RAID in El Capitan, which could be done using Terminal (or the hack that Blair subsequently linked to).
