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]

I have a PowerMac G5 and need to purchase an internal RAID card to create a RAID 1 mirror of the system drive... one that will allow me create a Hardware RAID 1 mirror, not software RAID through OS X.
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?
I've been trying to migrate data to a new RAID setup, but have been running into the error code 36 issue where Mac created invisible files are killing the file transfers. At any rate, I tried about three different directory cleanup utilities and for the most part got almost all the data to move. Now I'm onto the last bit which was giving me permissions errors as well.I used Batchmod to make everything read write and I ALSO CLEARED THE XTARS. Worked like a charm and everthing transfered. HOWEVER. Killing the extened attributes of the files turned them all into Executible files with no program ownership. BTW, there are font files so there are hundreds of them. Is there anyway to re-assign them or get some of the attributes back?
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...
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?
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.
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?
I need more storage and need it to be quick and redundant
I'm concidering 2 of either the WD thunderbolt duo 6TB or the LaCie 2Big Thunderbolt 6TB. I want to set each 2disk unit to RAID 1 and then srtipe them as RAID0 accross thunderbolt to hopefully result in one striped and mirrored 6TB RAID volume
I'm hoping yes because i've seen 4 of the WB unit daisychained as one huge RAID0 but I'd like the redundancy. also i want the resultant volume in exFAT as I am constantly jumping between OSX and Win 7

I have just finished setting up my first Lion Server from scratch on a Mac Mini with dual 500GB Drives which I set up as RAID 1. I have the server exactly as I want it, and before the users start logging on and it gets all screwed up I would like to create a disk image of it so that I could reinstall if necessary w/o having to start from scratch.
Is the process of creating a disk image for a RAID 1 any different than that of a disk image from a single drive set up? Will Disk utility just see this as a single volume or will it want to create a disk image of the entire RAID? i.e will the disk image be 1 TB (500 GB x 2)? And when it comes to reimaging my RAID, will I just recreate a RAID 1 and be able to write to it from that disk image?
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?
My brother is going to start school in June for Film. He is all set to buy a Mac and knows the software side of things but not so much the Hardware side.
I have a few questions:
1. Should extra hard drives be bought third party?
2. Should he do a raid setup for backups?
3. How much memory should he buy for Final Cut operations? (third party)
4. Should he look into getting a Dell monitor instead of Apple? What is a comparable Dell monitor?
I have 2ea 250GB internal HD. One with my apps and system on it and the other with no data. How do I mirror my drive with the apps and system? Or is that possible?
Information: Dual 2.3ghz PowerPC G5 Mac OS X (10.4.10) 8 GB ram / 2ea. 250 GB internal HD
When "Confirming Names" in the "XXXXX may also be in the photos below" section of Faces, is it possible to change or choose a name other than the Face you are within? Is there an option to do this - I cannot find it?
For example, I have a Face named "Christine" with numerous photos of Christine already confirmed. I also have numerous photos shown in the section "Christine may also be in the photos below".
I have 2 1TB drives coming in on Monday, and I plan to put them in a mirror RAID using Disk Utility. How reliable is the OS X software RAID setup? Would I be better to just manually backup from one drive to another? The drives will be for my photography, I wanted a mirror setup so I'd finally have a backup of my (current) 250GB's of photos. (Most of which I could probably burn to DVD's but humor me.)
If the RAID crashed somehow via the software, would the data still be recoverable? I have a MP and will be putting them in Bays 3 & 4. Also, is there any benefit to the different block sizes? Since my files will all be at least 7MB would the biggest block size speed it up?
I just got a brand new MAC PRO desktop. It came with a 600GB HDD. I purchased a second identical internal 600GB HDD. I wanted to do setup a RAID 1 using these 2 drives. Currently the main drive has the OS and all my other apps installed. I installed the 2nd drive and was fooling with disk utility. I'm not sure how to set this up however. I tried numerous guides online but I just cant figure it out.
MAC PRO (takes up to 4 internal drives) - currently installed 2 identical drives Leopard Using Disk utility
The RAID tab says "online" and the status is green (indicating the RAID is working). However on my desktop i see the 2nd hardddrive mounted with no contents in it. I just want to able to use the 2nd drive as a mirror so this way if one fails I'm still up and running.
I'm planning to setup a RAID on My Mac Pro (2006 2.66 Quad Core). I know Bootcamp not support Hardware Raid Card. Can I use the Hardware Raid Card for boot Mac OS X and storage Data, and use the onboard controller boot the Bootcamp Drive?
this is what im currently goin with.. SSD as boot/apps and a 1TB for data.. but a couple people suggest 1TB drives in raid.. 1. what do I need for raid? 2. how does it compare against the SSD+1TB setup? 3. can I add raid to the SSD+1TB and get more 1TB drives later?
Basically this would create a big 4 gig array that I could split into multiple partitions. I'd have mirroring and fast performance. I was wondering what the performance difference would be between the Greens and Blacks - Greens are known for worse performance, but I was wondering if in RAID 10 it would even matter.
I have a PowerMac G4 I'd like to use as an "experimental" backup machine. I am looking to try and make a RAID setup in it, and I'm no expert with that. I'm wondering if this is even possible, first. I'm also wondering if I can do this with 2 40 gb drives and a 20 gb drive. I want to make it so it appears as 1 drive. I'd be using tiger and a software RAID if that is of any relevance.
Specs: 500 MHz PowerPC G4 640 MB SDRAM No hard drives currently
Setting up raid 0 for my mac pro 3,1. Right now I have the stock 320GB drive that I use with Mac OS X, and an additional 500GB drive running Win XP through Bootcamp. I read on apple's site that you could stripe multiple drives to create a raid 0 to increase performance on the Mac Pro w/o the raid controller card. So my question is how do I do that? I'm in the process of picking a new 2TB drive to set up the raid with the 320GB OS drive. Since the 500GB one is dedicated for XP I don't think I could include it in the raid right?
I bought this Hard drive under the impression that its going to be easy install. I went through the manual steps to install all went ok to last step which is partition and format using Disk Utility. now i dont know what to do, is the hard drive going to do the Raiding, or I have to setup using Raid tap in Disk Utility? I tried doing Raiding using Disk Utility but couldnt do it, i thought maybe i cant because its hardware raid or i searched until my head exploded, and I feel its easy but i am not getting something tiny here.
I plan on using a set of 5 [2TB] drives in a RAID setup. Looks like WD is the manufacturer but I'm not really seeing a lot of input online for these other than that they have been recertified
I have a Early 2008 Mac Pro. I have the Apple Hardware Raid Card Installed. I have 4 2TB disks installed. Currently I've got the system disk setup in Bay 1 as a single disk. Then I have the disks in bays 2 through 4 setup as a raid 5. I've been thinking that I might be better off to make all 4 disks into a raid 5 array and then just make volumes for the system disk and my work disk. My goal is to have a system volume an a scratch/work volume for image and video editing.
I have two questions. Firstly, I am considering buying a western digital MyBook Studio Edition II [URL]. If I use time machine with this drive, will I be able to remove one of the drives and keep it off-site for safekeeping and have time machine continue to backup on the remaining one as usual? Secondly, if I remove drive #2 and keep it off site, would dropping it back into the raid setup update drive #2 with drive #1's current time machine backup? I'm new to raid, and I am basically trying to have a time machine backup, and a off site backup.
In my Mac Pro I currently have the stock HD as my OS/Home drive, while the other two 1TB WD Black drives are RAID 0 partitioned into a 1.5 TB Data drive and 256GB Scratch. I have these and my OS/home drive backing up to time machine but when I eventually upgrade to 10.6 (and probably clean install) will I lose my RAID setup and have to re-create it byte-by-byte in order to restore from my Time Machine backup? Or would I have to do the 'upgrade' installation to get around this since I used Disc Utility to create my RAID setup?
Yesterday I bought a new Mac Pro. I absolutely LOVE it, and don't care if they replace it tomorrow. It is a terrific machine. I do want to set up two sepeate RAID arrays inside it, and could use a little help, as I've never done this before. I want to set up one array, of two large (say 1TB) drives in mirrored (RAID 1?) format for all my data. I want to set up another of two smaller (300GB) WD Velociraptor drives, which I already own, in striped (RAID 0?) format for the operating system, and my applications, as well as a bootcamp partition.
This is where it gets complicated for me. Much of my data is on one of the velociraptor drives in another computer. My question is, can I install the two new 1TB drives, set them up as RAID 1, using the original drive that came in the Mac Pro, move my data over from the old computer, then install the velociraptors, set up that RAID 0 array, and install the operating system. In other words, will the "new" operating system recognize the data raid array that I had created with the "old" operating system?
An easier question. When setting up the operating system on what will be my new RAID 0 array, do I just boot from the CD? and secondly, do I first set up the striped raid, and then install the operating system, and then the bootcamp partition? Or is there a different sequence to use.OK finally, when booting into windows through bootcamp, will windows be able to see the seperate data RAID array?l
This is what I've done so far: I set a Stripped Raid Set with two drives: a Seagate 500GB @7200 and the original WD 640GB @7200. Before setting the Raid, I partitioned the latter in two: a 500GB and a 160GB, so the extra space is not lost. The Raid was created successfully (using the disk utility Raid - no special hardware). So far, is this OK (specially the partition part)? Now, my question is, what's the best way to migrate all my apps and data, from the original single boot drive I've been using until now, to the Raid - so the benefits of the raid are most apparent?
a) As soon as the raid was set, still inside Disk Utility, I used the Restore function, using the original boot volume as source, and the raid volume as target. This is in progress, with an eta of 4 hours, but I can stop it at any time... is this the best way? b) Another way that occurs to me, is to clone the boot volume to the Raid using Superduper or CCC....? c) Or perhaps I should make a clean OS install in the Raid volume, and then use migration assistant or other method to bring the apps and data to the raid?Or, something else I haven't thought of...?
