Mac Pro :: Mirror RAID Or A Stripe RAID?

Feb 14, 2010

On my 2009 Mac Pro, OS X's disk utility seems to allow the provision of making a mirror RAID or a stripe RAID.

Is it possible to shove in 2 drives, make a RAID 0 for two of them, and then add in 2 more drives to make a RAID 1 out of that RAID 0? (a RAID 0+1?)

Mac Pro :: RAID 5 Volumes - Create In RAID And Disk Utility?

May 20, 2009

I have a new Mac Pro Quad 2.93 with the Mac RAID card installed with four 1TB drives setup in a RAID 5 array. When creating the volumes in the RAID utility, you can not edit them, resize, etc. If one large volume is created in the RAID utility, you can then partition that one volume using the Apple Disk Utility, which then allows you to resize if needed.

Mac Pro :: Setting Up RAID 1 Without RAID Card?

May 15, 2009

I have never setup RAID before and this question may be totally stupid for that matter.

Can I setup RAID 1 (or call it mirroring) without the RAID card? I have two 1TB internal drives in my Mac Pro and I want to mirror them. I don't want to spend another 700 bucks just to setup a mirror.

Disk Utility shows some RAID options, but I am not sure how to use them, or if they will work at all without the RAID card.

I have a RAID 0 set up with two 1.5TB HDs. I am doing some reorganizing and want to take all the data on the RAID 0 and move it to one of the hard drives in the RAID 0 and create to single drives. Is there any way of moving all the data from a RAID 0 onto one of the HDs?

OS X :: Unable To Know About Mirror Raid?

May 9, 2010

I have a 1TB disk. It is now almost full. I just got a new 1TB disk and I want to make a mirrored RAID set of the two. If I create a RAID set in Disk Utility, does that erase my first disk? Or does it just mirror everything to the second?

Mac Pro :: Remove Mac Raid Card From System / Drives Are Not Recognized At Boot Up

Oct 15, 2009

So I have followed a bunch of the 'MacPro with mac raid card users wanting to do bootcamp' threads. I have attempted all the hacking required but have not been successful. I heard that bootcamp 3.1 will fix this problem possibly... so in the mean time I would like to remove my SAS drives and raid card and just use the sata drives that I have to do Mac OS and Windows.

I have removed the card but when I plug the drives in and boot up the machine, the drives are not recognized. Is there some plug that I need to reconnect somewheres?

Hardware :: Can I Boot From A RAID 1 (mirror) In My G4?

Oct 2, 2008

I don't know where I read about this, but I am getting ready to redo one of my systems. Currently it has 2 identical 250GB Hitachies, which use Super Duper every Sunday to backup. I tried doing a RAID 0 back in like 2004 on a system that had 4x60GB. I found out through trial and error and then later reading that you can't boot from a RAID in a Power Mac G4. But like I said earlier I don't know where I read this, but someone stated I could boot from a RAID 1 (mirror) in my Power Mac G4. Is this true? or not? Is it possible to boot from a RAID 1 in a Mac G4 but not RAID 0?

Something tells me this isn't going to work. I have a 10% glimmer of hope that maybe it will just see the drive as a regular drive. This would really be great. If anyone knows the answer to this puzzle please feel free to let me know...

Mac Pro :: Bootable RAID 1 Mirror Configuration?

Sep 28, 2009

Having never set up a RAID config I was hoping I could get a little confirmation on setting up. Firstly, all data will be backed up using a NAS (maybe a time capsule), so at the moment I am just looking to mirror the primary drive of a Power Mac G5 incase of hardware faults.

The G5 is acting as a server and I therefore want to arrive at a situation that if a drive fails, the machine will still boot perfectly from one of the redundant disks (and of course notify the user to the failure), i.e. a bootable RAID 1 configurationAs I understand it, I can only achieve this using a dedicated RAID controller (i.e. this can't be done via a software raid)? Is this the case?

Mac Pro :: Multiple Hard Drives Boot Drive & Internal Raid

Jul 11, 2009

I just got a used mac pro quad. I plan to use it for video production- final cut pro, pics - aperture, and music production- protools. THe computer came with 3 - 10k rpm 160g hd's. Two of them are set up as a raid 0. I like the idea of having a faster drive as a boot drive, but 160 seems kind of small to me as the drive to run memory hungry apps and the operating system. Am I right? I could go to a 300g 10k rpm drive. I am also thinking about getting a bigger drive, say a 750g or 1 tb 7200 rpm. Should I use this as the boot drive or as a secondary storage drive?. If it's the boot drive should I add the other 160g 10k drive to the raid or keep it separate? I assume that neither way would be wrong, nor create a problem, but since I haven't put anything on it yet, I'm wondering what would be the most efficient way to manage my files and get the most out of my computer.

OS X Server :: Create Mirrored RAID Set From Existing Drive And New Drive?

Oct 4, 2006

I have a PowerMac G3 running OS X Server 10.4.7. There is an 80GB ATA boot hard drive and a SATA card and two 250GB SATA drives. One SATA drive is existing and has data on it; I just installed the second one because I want to mirror the 1st drive onto the 2nd one.My questions are: how do I do it? When I try to create a RAID set in the Disk Utility GUI, it says all data will be destroyed. I cancelled that.So I tried diskutil enableRAID mirror disk1, which told me I could only mirror volumes.The volume name is RAID, so I tried diskutil enableRAID mirror /Volumes/RAID which gave me an error "Error enabling disk to RAID Could not unmount disk (-10000)"

OS X :: Moving A Mirror Software RAID To A New IMac?

Nov 24, 2009

I have taking the plunge and bought a new i7 iMac. On my current machine I have 2 WD external USB drives (1TB) in RAID mirror, done through Disk Utilities. I am looking for advice on the correct way to move this to my new machine. Do I simply plug them in, and OSX does the rest? The data is very valuable, and I don't really have enough space to copy it all / back it up before i move it. Being a mirror, it is essentially is my backup.

OS X V10.7 Lion :: How To Setup And Confirm RAID Mirror

May 23, 2012

Literally just got shiny new miniMac Server with the dual 70GB internakky hard drives/disks with OS X 10.7.$ LION pre-installed. What a nice machine in a super cool box Seemed to bootup and run fine!Now my issue (there will be more for this MAC newbie):How to setup AND more importantly (item B below) CONFIRM that a RAID MIRROR is working? Want nothing fancier than 2-nd drive is exact duplicate of 1-st drive at all times. That is, an 'active and full up-to -the second" backup of the main 1-st drive.I have done nothing to 1-st drive as it came from APPLE.When I try to setup RAID set using DISK Utility, I get message about system(1-st drive) can't be used in a RAID or such.

yet I can add 2-nd drive to what I tink is a RAID set and then 'Enable' it.It seems to add another entry to thr left-side of drves list panel but not sure that 1-st and 2-nd drives are BOTH in the new "RAID SET' or that the set just consists of the "single" 2-nd disk? B. I don't think that 1-st drive data is actually being duplicated to 2-nd drive.For instance, how do I know that it was 'caught up' to match 1-st drive AND then is [code]

Mac Pro :: Changing From Mirror Raid To Two Independent Disks?

Aug 20, 2014

Can I just remove one of the drives and what are the consequences of the removal. I would like to go from a mirrored raid to a carbon copy of the disk which would be updated weekly and use Time Machine in between.

Do I open up a can of worms  - my suspicion is that if I want to do that I'll have to reformat the RAID with the loss of all data.

Any workaround short of making a copy, removing the raid and restoring the data?

OS X Server :: Breaking Xserve Software RAID Mirror?

Jul 28, 2006

I want upgrade our xserve from 2 x 250GB mirrored discs running Mac OS X 10.3.9 on xserve to running 1 x 250GB system disc (keeping other as spare) and 2 x 500GB mirrored data discs. (Then upgrade to Tiger).

Can I break the software mirror with:
diskutil destroyRAID /dev/disk{x}
or does this destroy the data too? Would I be left with two working, bootable discs or just two RAID slices? If the latter, how can I convert them into 'normal' bootable discs?Would it be better to upgrade to Tiger first? Or not make much difference?

Hardware :: Dual Drive Storage System With RAID

Jun 12, 2009

I was looking at this HD: [URL]. Could someone please summarize for me what is a "Dual-drive Storage System with RAID?" I have some ideas of what it is... it involves mirroring, and holding two copies of data to make sure one doesn't lose data, correct? This is a 4 TB drive... what if I want 4 TBs worth of storage and not two copies of 2 TBs worth of storage? Am I allowed to turn mirroring off and get a straightforward 4 TBs worth of storage? Please feel free to throw in any quick facts about RAID you may want to.

Hardware :: Can A RAID 1 Guardian Maximus Rebuild Easily / Have Partitioned The RAID Set

Dec 2, 2009

I just bought a Guardian Maximus RAID1 kit and I have two 1TB drives in it. I'm using it over Airport Extreme as an airdisk (mac osx 10.6.2)

My question is simply: am I running a risk by partitioning it into two partitions? Should I ever have to rebuild the failed disk (which I understand is really simple with the Guardian Maximus) - will it have trouble doing two partitions? I'm using one 500gb partition for time machine and one 500gb partition as redundant itunes/media.

Mac Pro :: Get A Highpoint Raid Controller And Put Those 4 Drives In A Raid 5 Array?

May 1, 2008

I have a macpro with 4 x 1tb drives

Is it possible to get a highpoint raid controller and put those 4 drives in a raid 5 array (and then create partitions inside that array) - or do you need to have 1 drive by itself for the operating system, and then create a raid array using the remaining 3 drives?

Lastly, are the highpoint 3500 series a decent card? and fully compatible?

Mac Pro :: Raid Speed ... Raid 5 Vs Straight Sata HDs

Jan 28, 2008

ive put 4 of the hitachi 1tbs in my new mac pro.. and i really want to do Raid on them eventually.. and buy the pricey apple raid card.. i'll do it.. but speed wise:

How fast is a Sata connection straight from HD>Motherboard... ~75mb/s?
Is the Raid 5 config with all those drives much faster... around ~110mb/s?

Do you know if there is anyway to get a 5th drive into the raid 5 array? using the ODD space.. or some externals too... i need as much as space as possible...

And boot camp wont work with raid card anymore? I was thinking to have the startup disc be a raptor to increase speed on the apps, how would it integrate with the raid card, etc

Mac Pro :: Software RAID Versus Hardware RAID?

Apr 20, 2010

I am planning on getting a 2010 MP when they come and have a question about it. I am 90% sure that with my budget, I will not be able to after a RAID card. I am wondering if software RAID would be alright or if it's so bad it's not worth doing. Also, there is small chance that I could buy a RAID card later on, how would I install it? I will be using it for 3D animation with Maya and some zbrush modeling. Also I will be doing some Photoshop and illustrator and maybe some gaming on win 7 boot camp. Feel free to list any other pros and cons about either a software RAID or hardware RAID, I wana make sure I have all the details before making a final decision on it.

I know it is possible to add disks to a concatenated RAID set without destroying the data on the disks already in the set, but I cannot get Disk Utility to let me create a single-disk concatenated RAID set.

Mac Pro :: How To Find RAID Card?

Apr 16, 2008

I have a question about Apple's Mac Pro RAID card that I couldn't find an affirmative answer to by searching.

I know that the Apple support documents state that only Apple hard drives are supported by their RAID card. But by that, are they implying "official support" in terms of warranty or "not gonna work at all?"

The reason I ask is obviously that I'm in the market for a new Mac Pro. I need a workstation platform for video editing.

But I don't necessary want to pay significantly higher prices for Apple-supplied hard drives if I don't have to. Further, it's impossible to tell what drive make/model you'll actually get going this route.

So I guess my question is aimed towards anyone who has successfully configured 3rd-party hard drives on the Mac Pro RAID card, if it's even possible.

I like the idea of keeping the cable runs neat and clean while still having hardware RAID functionality and not having to worry about finding a 3rd-party bootable RAID card with Mac OS X drivers.
