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?
View 2 RepliesI 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.
View 2 Replies View RelatedOn 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?)
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.

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?

Ive heard conflicing statments that the raid is software/hardware. anyone know for sure what it is (Im not talking about that card you can buy).
If it is software raid does this take a toll on the processors? is it serious or does it not matter at all.
IF it does matter. should I buy a exteran raid card? is there a mac compatible one. I just need basic raid0.
I just bought 2 samsung spinpoint F1 750s in anticipation of my new mac. But just want to make sure that raid is a wise decision.
for those who are thinking about replying about the dangers of raid. I know. I have time machine. if the raid goes down then so be it. such is life. I will have backups.
OK I do some Video Editing and Motion Graphics with FCP and Adobe After Effects.
I have a Mac Pro 2009 with 4 1TB Drives and 2 1TB Lacie Fire Wire 800 Drives.
This is the setup i have
1st Drive Mac OSX
2nd Drive is Windows 7 OS
3rd & 4th Striped and Mirrored to the 2 Lacies External Drives that are Striped. (raid 1 + 0)
My first question: is this a bad system? should i set it up a different way?
Second: is If a Drive goes out in the Raid 1+0 how will i know and how can i put a new drive in to fix it? How does this work?
Third: I set the RAID up with disk utility, is this ok, bad or good?
Fourth: IF the the OS Drive goes out will and i replace it and format it, will the RAID 1+0 Still be there? some where i read that its OS dependant?
I have an 2008 2.8 octo with the stock 320gb WD drive. I use an external 1tb Seagate FreeAgent to backup. I use Super Duper to backup a bootable clone. I am interested in both more storage space and faster response.
1. If I were to get another of these WD 320gb units and make a striped raid using disk utility, I would get a 640gb volume, correct?
2. Could I back up the 2 drive raid volume to my external drive just like I do now?
3. Could I restore to either a striped raid or a single drive off the backups on my external in the event that after a hardware failure I decided either to replace the bad drive or just go back to using a single drive?
4. Would a two drive raid comprised of two 8mb cache WD 320gb units perform as well or better than using just a single Samsung Spinpoint drive, which is the other option I have considered?
The WD unit is $49 shipped, and a 500gb spinpoint is $59 shipped, so cost is about the same.
I just want to get the most bang for the buck out of my brokedick $50 storage upgrade, and I also want to be sure that I have a little piece of mind with my external drive backups.
If I needed to mount two drives in the empty optical bay and put both of them on RAID 0, would this and this be the only 2 things I would need?
Also, with the Pro Caddy 2, would I need one of their PCIe cards? Their site says that a card is needed, but since I would be getting the RAID card, would I need to even get one of theirs or would the RAID card be all I need?
They give three options for PCIe cards with the Pro Caddy 2: none, nonbootable PCIe card, and bootable card.
So would I be good with just the areca 1210 and the Pro Caddy 2 without a card or would I need a separate card for the caddy?
My MBP is 5,1, at last few months I use 2 HDD in raid 0, it fine and smooth, but after I upgrade 2*SSD ( OCZSSD2-2VTXE60G ) the nightmare is coming, only see one SSD (in org hdd bay), the optical bay never see, at first time I thought may be SSD is dead, so try to replace them, both SSD is work, second thought is optical bay dead, so put the hdd back, it work.
I don't what's going wrong, I just thought optical is not fit OCZ, may I know who is using OCZ in raid 0 please kindly tell me which optical you using.
i would like to reserve my 4th bay for windows only drive and a software raid will be used for these.
what would you think is a better set-up,
3x internal drives (all of the same model, probably WD 640's) set in raid 0 (both serve as boot drive and scratch disk) occupying bays 1, 2, and 3. In this set-up, everything (DVD's, music, photos, final cut media) would be stored on this array.

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.

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.

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.
