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.
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 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?
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]

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 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?
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?

Going to setup a raid using apples utitlity to get a raid 0 of two 640 blacks for my 2008 MP. I have adequate back up, including time machine and two separate back up discs that I keep information on. My macbook pro also has the same information with its own time machine back up.
So I have to wipe my original 640 so the new raid can be created I assume. Should I restore from time machine to put my info back on after creating the raid setup? Is there an easier way, one that doesn't require me copying all my information over?
Upon booting the machine, the LCD display flashes a proper view of the login screen for about 1 second but then goes dark. When an external monitor is attached the external monitor works perfectly fine -- the only trouble being that the external monitor is not currently set to "mirror" so it is impossible to log in and access the machine. The IT dept at the institute has a monopoly on repair of computers and so the quick answer -- take it to Apple is not all that easy. Is there a way to:
1) set the iMac to mirror display upon booting up by some clever key combination? 2) set the machine to mirror by remote access and command line methods? 3) mirror by changing something using target mode? 4) or the obvious...somehow login using the real estate provided by the external monitor.
Also has anyone seen this problem with iMac displays? An Intel iMac I think 2.16 Intel Core 2 Duo processor running Tiger.
I have an iMac and a mbp, both intels & running 10.5.8. I work on the road and wish to have both computers contain the same information with out over writing the new files. i.e. - I work on a word file at home, work on the same file at the office and then record my band before heading home. When I get home, I want my home computer to have the updated word file and back up the logic audio files. The other part of this is so that my iPhone will sync with both computers. MobileMe was kind of the right path but I didn't quite do the trick. How do I do that?
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.
I have a Lacie ext hard drive with 2 x 250gb HD that were one RAIDed into a single 500gb HD. I ran this update Lacie firmware update: http://www.lacie.com/support/drivers...r.htm?id=10053 And now my HD will only show up as two separate HDs of 250gb instead of a single RAID HD of 500gb.
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?
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.
I'm using the software RAID right now. Everything is set as RAID 10. I want to move to a RAID card� if I keep it as RAID 10 will I still need to redo everything?
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
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?
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 was wondering if anyone had successfully installed and 2nd hard drive in their iMac?I have a 2 year old 2.8 24'' iMac and the performance just isn't cutting the mustard, it's all hard drive related and I already have a decent 1TB drive in there.I was thinking of perhaps swapping the optical drive with a second hard drive for RAID0, but not too sure if there will be space and was wondering if the optical drive is a standard SATA connector, or if there is some way I could run a SATA+power cables externally?
I have a couple of questions regarding backing up my external drive. I've got a 2TB external drive with about 1.5TB of movies, Music etc. I've got another identical empty drive that I want to keep a backup of the first drive on. So my question is what is the best way of backing up this data? I thought of using disk utility(I'm running snow leopard 10.6.4 if that makes any difference) to created a mirrored RAID set. If I plug in the empty drive then create the RAID set will my first drive get wiped when the set is created? or with it leave the data on the first drive intact? Or should I just use something like crashplan to backup to the 2nd drive?
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 currently sync my iPhone, iPad and iPod Touch on the XP box. My goals are to move all my songs, apps, movies/TV shows etc. over to my new mac. I want to stop using the XP machine all together.
In terms of steps. I'm thinking I need to do this:Ensure both XP and Mac are running the most current version of iTunes - if not upgrade them Sync and back-up each device one last time on the XP machine Transfer the data (via the apple FAQ above) Sync each device with the mac? Will the Mac recognize the devices just like the XP machine did? Will I need to transfer purchases from each device?
The case is this: I have a 200 GB Maxtor harddrive onto witch i want to copy all the video, zip and other files from my imac. I have allredy copied most of them by using a memory stick and taking it over to a PC and from there over to the Maxtor. But the files i have left on the mac is to large for the memory stick.
The Mac can only read, and not wright the Maxtor. But i just can't understand that i can just copy the files from the Mac to the Maxtor via a PC, but not directly?? isnt there a way to copy the files directly to the Maxtor?
I don't know much about filesystems but on my imac it says someting with RAID and aufofs. I have also understood that i can format the Maxtor to FAT-32, but some of the files are greater than 4 GB, so that wont work right?
I am be watching a movie on my iMac, or just do other tasks, and everything would all of a sudden freeze up on me, with the mouse cursor the only thing moving around. The system wont let me do anything, and I have to hold down the power button to shut it off.
