RAID with Disk Utility question

I've setup a RAID array in disk utility for an external SATA NAS that I have. The Silicon Image Si3132 drivers are not working for Snow Leopard (the SATARAID 5 drivers) so I've installed the base non-raid drivers for 10.6.
I'm using Disk Utility to setup the RAID for now until I get updated drivers from SI. Here's my question:
Let's just say that my Mac Pro one day decides to die and I have to rebuild a new OS on the machine. I will then have this external drive where I've configured a software RAID with Mac OS X. Will I be able to rebuild this RAID and recover the data, or will I lose all of the data if the Mac needs to be rebuilt?
The external enclosure has its own controller, but these silicon image drivers do not seem to want to work as they are kernel panicking.
Will I be able to recover the RAID config with disk utility if I rebuild the machine? My thinking is NO

You have four internal hard drives; ability to boot from FW or USB, and I would include TimeMachine and clone (Carbon Copy Cloner or SuperDuper). Some WHS NAS servers also support TimeMachine and SuperDuper, but I would have local backups. Two minimum.
I would not rely on SI or RAID.
And all you need to boot from, and I'd have at least two, is a basic 30GB partition for Mac OS: a working copy of your system as is, a copy of last version installed also, AND, one "emergency" boot partition for disk maintenance and repairs.
Then use NAS as second line of backup for your data, disk images, etc.

  • Raid with disk utility

    Hi there
    I have an odd setup, however let me explain the whole situation.
    I recently bought 2 external firewire drives with the idea of setting up a raid mirror so i could backup all my data safely.
    However, it appears I cannot plug both drives into my mac at the same time using firewire, or they drop off the mac. I have read some other forums and found that you need to plug each drive on a different firewire card. As my G4 has only the one set of ports this is not possible without buying an additional pci card.
    However they support usb as well. I can plug one drive in as firewire and the other via the usb at the same time fine, but now cant get the disk utility to raid the drives.
    Is there a way to do this or to "trick" osx into thinking they are both firewire drives? Any hack or workaround welcome - even if it requires editing odd files via the terminal as this is a test system anyway and can reinstall if i need to.
    Pete

    Hi Pete;
    RAID 1 or mirroring is NOT a good backup solution.
    The primary purpose for RAID 1 is to protect from disk failure.
    By way of an example as to why RAID is not a backup solution, consider what would happen if you had an application which had a dozen files opened. The application aborted taking all of the file with it.
    How could recover with RAID 1? You could not because as soon as the application aborted all of the files would be removed from all of the disk in the RAID array. You would have no way to recover without a backup of the data. Hence data on RAID 1 must be backed up.
    If you still want to create this RAID 1 array, I would certainly recommend that you don't mix USB and Firewire. Any RAID is dependent on the various parts of the array being similar as to connectivity and hardware.

  • Repairing disk with disk utility question

    hello,
    I had a few questions regarding disk utility
    1. I have 2 user account on my computer, one admin, one regular
    2. run disk utility from regular account...tells me i need to repair disk
    3. run disk utility from admin account...tells me the disk is fine
    4. I want to run the repair disk function from my boot disk to be safe
    5. will it erase my data or corrupt any data at all...I do have backup, just want to be prepared for anything

    Hello! You can't repair the boot disk unless booted from the install cd/dvd. It sshould do just fine repairing the hd while booted from the cd/dvd but it's always a good idea to have everything backed up. Personally I use multiple bootable clones. Tom

  • Can I create a raid drive with disk utility

    I recently bought a 2TB seat gate external drive.
    I want to use this drive with time machieve as well as set it up as a raid drive to strode photos.
    Is this possible to do with disk utility?

    Hello
    you can not make any kind on RAID type with only one hard drive you need at least tow drive to perform a RAID volume
    then , hard drive utility can be use to perform software raid  ( Level 0 an Level 1 only )

  • How do you setup RAID 10 with Disk Utility?

    I read a post that indicated a Mac Pro user created two mirrors and then striped them with Disk Utility to create a RAID 10.
    I tried this but Disk Utiity will not allow me to stripe the two mirrors. I tried dragging and using the "+" button. In each case no RAID 10 could be created.
    Could someone list the exact procedure for creating a RAID 10 using Disk Utility?
    Thank you

    I have Mac OS X Build 8K1124 and I believe that came with my Mac Pro as I've not required a Mac OS X update via Software Update.
    Now, I have to honest, I'm not entirely sure that was the exact process. As you can appreciate I don't have another 4 drives to try this again so I'll do my best here.
    It's definitely right up until the part of making the mirrors and unmounting them, that I know for sure. What I don't remeber is what I had selected to get to the RAID tab to create the Stripe Set. I believe I had one of the mirror partitions selected, that is, either "disk5" or "disk6", which brought up the RAID tab that then allowed me to create the stripe set.
    I then created the set and then dragged the mirrors (I believe disk5 and disk6) into the set.
    If you can't do this can you let me know how your situation deviates?

  • Cany you help me with Installation and Disk Utility questions?

    Greetings.
    I'm just learning this stuff, so your responses in basic terminology would be appreciated. (Instruct me as you would my grandson). I have two questions.
    First, I bought a used dual 450 from a friend, and, as I do not have the disks or license for the OS, I decided to make it legal by purchasing, registering, and installing new Panther DVDs. As I have been running 10.3.9 and the new disks are labeled eMac 10.3.3, is there anything I should or should not do in the process of installing the new disks? Do I need to install 10.3.3 and then download the 10.3.9 update? Will I lose anything in the process? I assume the eMac disks will work OK on a G4 tower.
    Second, After power failures (common where I live), when I re-start the computer, it won't progress beyond the spinning spoke thing (I don't know what it's called), so I have to shut the computer down, and, after one or two more attempts to start up, it seems to start up OK.
    I was told that, after a situation like this, I should start up with the install disk and run Disk Utility to repair the start-up disk.
    The problem is that when I attempted to do this with the new DVD (again, I have not installed the OS from the DVD yet), the computer started up fine, but Disk Utility ran for a minute or so, then gave me the following message: "Disk Utility has lost its connection with the Disk Management Tool and cannot continue. Please quit and relaunch Disk Utility." This happened twice in succession. I quit Disk Utility (although it warned me that I could rended the disk inoperable). The disk seems OK, but I don't know what the problem is with DIsk Utility, or what to do.
    Thanks for your help.

    Hi Jerry:
    Getting back to the problem you're having with Disk Utility, a number of people have encountered this following an update to iTunes. If I understand correctly, when you bought the G4 it came with Panther installed, which your friend had updated to 10.3.9.
    In an earlier post, Kappy posted the most succinct work-around I have found for this error:
    1. Navigate to the /Library/Receipts/ folder.
    2. Locate the iTunes.pkg and iTunesX.pkg files and move them to the Desktop.
    3. Run Disk Utility and repair permissions.
    4. Move the .pkg files back into the /Library/Receipts/ folder.
    Give it a try and let us know how it works. As for your installation DVD, I have to concur with the others who have posted: it's meant specifically for one model of the eMac. It may work on another mac, but odds are it'll be problematic.

  • Xserve RAID won't RAID in disk utility

    I have a XServe RAID that won't RAID in disk utility. The XServe is fully populated and there are two arrays created. Both of those arrays show up in disk utility and will only be partitioned with an Apple Partition Map. If I try to partition them GUID, that partition fails (system formatter failed). Once, I partition them APM, two volumes show up on the desktop. Then, I try to create a software RAID with those two volumes and I can not get the volumes to RAID together. The error message in disk utility says (RAID can not be modified). I have checked the system log and it says something about a socket error or that it can not bind. Does anyone have any ideas on why I can not create this RAID?
    My end goal is to have 2 hardware RAID 5's and put a striped RAID set on top of that to have one large volume for Final Cut video editing.
    I'm using a Mac Pro with Atto Celerity 42ES fibre card.
    Thanks

    This may be a little too late, but maybe it will help. I'm not sure why this happens. I reinstalled my server, and I could not access the drives, even though they showed up in disk utility (as a blank file).
    Here is what I did to fix it:
    1. Open up Disk Utility
    2. Make a disk image of the drive you want to mount, save this somewhere accessible (i saved it on another one of my RAID drives)
    3. Erase the disk, it should then mount and be accessible
    4. Restore the image onto the drive.
    Cheers!

  • "Create" button dim when attempting to setup mirrored RAID in Disk Utility.

    I'm trying to setup a mirrored RAID in Disk Utility (v10.5.6) in MacOS 10.4.11 on a PowerMac G5. I've got the System and all of my files on a 500 GB Seagate internal drive and I've added a blank 500 GB Western Digital internal drive to be the mirror. When I boot from the Seagate drive and run Disk Utility, I can follow all of the instructions for setting up a mirrored RAID (except the last instruction):
    1) Launch disk utility.
    2) Select my boot drive.
    3) Click on the RAID tab.
    4) Enter a RAID Set Name and select a Volume Format (Mac OS Extended Journaled).
    5) Drag a drive or volume to the set. Okay, I actually have a problem here, because if I drag the boot volume or drive to the set, nothing happens (it doesn't appear in the selection box). So I drag the blank volume to the set and it shows up in the selection box.
    6) Select RAID type (RAID Slice).
    7) Click the "Create" button.
    That's the step that I can't complete; the "Create" button is dimmed (grayed out, disabled). My boot drive isn't partitioned (it has just one volume), I've run Disk Utility to repair Disk Permissions before I attempted to set up the RAID, and both drives are formatted as "Mac OS Extended Journaled." The only potential cause I can think of is that the two drives I'm using, though they're both 500 GB drives, are from different manufacturers. I can't imagine that would make a difference though.
    Why is the "Create" button dimmed?
    Any help would be GREATLY appreciated!
    Thanks,
    Scott

    Hi there,
    Thanks for your help!
    Your explanation makes sense. I've just recovered from a hard drive failure and although I'd backed up most of the files the night before, I still lost a day's worth of email and several days worth of other files. Mirroring appealed to me because then I'd always have a completely up-to-date copy of everything, but your bad experiences with it give me pause.
    Is there another backup strategy you can recommend that would give me really up-to-date backups of my entire boot volume?
    Thanks again!
    Scott

  • Looking for opinions on Apple's software RAID in Disk Utility

    I'm thinking about making a stripped RAID (RAID 0) with Apple's software RAID in Disk Utility. How reliable is it, and will I see a huge speed improvement over just having two independent drives. This RAID will also be my boot drive. Is that a good idea or should I have a separate drive for that function?

    It depends. And seeing you don't have a lot of exposure to RAID, it depends, you still need even more to regularly backup, and depends on the drives to some extent. RAIDs are great for some things, and the sustained reads and writes look good in some simple benchmarks, but for most users, they are better off with a really good fast 10K Raptor or something as a dedicated OS/apps boot drive.
    http://www.barefeats.com/quad07.html
    They did some earlier tests on RAID for boot drive, which you might want to look into.

  • Adding Drive to Concatenated RAID in Disk Utility

    Hello,
    I'm having a spot of trouble with Disk Utility. 24 hours ago I added a new drive to a Concatenated Raid through Disk Utility, and clicked Update to set the process going.
    Now it's not responding. It just claims to be updating. I struggle to believe that it takes this long though!
    I didn't format the disk before adding it to the RAID. Is this what's causing the upset?
    When I try to cancel it tells me I risk losing data on the disk. I'm not sure if it means the new disk or all disks on the array - which is a terrifying prospect. If I quit Disk Utility, will my existing data on the array be safe?
    Thanks in advance for the help,
    Ben

    The drives are in Sonnet P500 enclosures and connected to the MacPro via a Sonnet SATA card.
    On purhcase I was told this could be done, as it's a Concatenated JBOD setup. For a better description of what I mean by that, this wiki article describes it well http://en.wikipedia.org/wiki/StandardRAIDlevels.
    Does this provide any further clues?
    Currently there are 7x 1TB drives in 2 enclosures. I've now added 2 more 1TB drives. I can currently see and continue to use the data on the existing 7 drives. My worry though is that if I quit the disk utility I may lose the data on the 7 original drives.

  • Repair Permission with Disk Utility in Snow Leopard?

    After upgrading to SL, tried to do a repair permission with disk utility (a few times) & i got this "Warning: SUID file "System/Library/CoreS...as been modified and will not be repaired." ....is this normal????

  • Can Time Capsule hard drive be accessed with Disk Utility? I'm having issues...

    How does one mount , inspect , verify , and possibly repair a Time Capsule hard drive  with Disk Utility ?
    My 500Gb 1st gen Time Capsule  ( used wireless with Airport)  has quit backing up new data . ( iMac Core2Duo, Snow Leopard) .  TC  says it needs 238 Gb of available space, but only has 35 Gb available. So it quit doing new  incremental backup altogether. It's almost like it wants to start over.
    Airport connection seems good.  Time Capsule seems healthy enough ( for being 3.5 years old) .  I really dont want to lose the data on the existing backup.
    What is the nature of this glitch ?

    I'm sorry , LaP , but " Time Capsule become too full " is not the cause of my problem .
    In fact, I just got done pruning the iMac system hard drive a little  to free up some  10 Gb of new space , yet created only maybe 1-2 Gb of new data to archive. The TC had been doing regular daily backups without issue and Time Machine  was showing me stuff from about ten days back.
    The TC informed me it needed 235 Gb of space but only had 34 Gb available. That 235 Gb needed is totally in error.  My problem more resembles corrupt hard disk directories . Maybe Permissions ?  which is why I asked about using Disk Utility.
    Yes, I do need a newer larger TC, but pigs don't fly and money does not grow on trees to make tha happen. The backup I have now is fine and should work if I need to restore anything in the forseeable. New data will not be archived, alas.

  • I can no longer repair permissions with Disk Utility, v. 13

    After installing iTunes update 11.1, I can no longer repair permissions with Disk Utility, v. 13. When I attempt to repair Disk Permissions, there appear dozens of items showing that "Permissions differ on "Applications/iTunes.app....", then it says that it has been repaired. However, when I do a second or third repair immediately afterwards, I see the same thing again.

    I'm trying to backup a my hard drive with disk utility but I'm getting an error  Unable to create Backup.dmg" (input/output error). Is there any other way to save my data? I believe my hard drive is failing or corrupt file. I can't boot up. Grey screen and spinning wheel. I've tried everything https://discussions.apple.com/message/20580424#20580424
    any help will be greatly appreciated.

    Check here. Also have you done a TimeMachine back up?

  • Cant restore my macbook with Disk utility and my .dmg image

    My macbook would not boot anymore. Stuck on gray screen with apple logo, spinning wheel and a loading bar for a while after shutting off.
    I was able to get to Disk Utility in the recovery mode and, after a while, was able to make an image of my filesin an attempt to back them up.
    The .dmg was put on an external and i checked it on my imac, i could open the .dmg file and browse all my files from my macbook, so those are safe!
    After that i tried to wipe the SSD of my macbook and put the image back but that didn't work, also some resource is busy errors.
    After trying this a few times without succes i figured i'd try to do a clean install. This worked.
    My macbook air is working again but if Iuse Disk Utility in the recovery now and try and restore my image (.dmg file) it gives me Restore Failure; An error (-16) occured (resource busy) as well. I also tried to copy the dmg onto my macbook and run disc utility when booted into OSX. I open up the back up .dmg with Disk utility, then i go to my macbooks partition (Macontiosh HD) and use that as a destination and drag the mounted image as the source as shown on the image below. Am I doing something wrong here?
    Doing this i get an error as well: (-119,930,878) Resource busy as you can see.
    What can i do to get my image back on my macbook? Any 3rd party software?
    I considered just transferring the files after opening the .dmg file but this works only for documents and not for programs and settings of the default apps.
    I've looked all over the Internet and it seems more people have had this error but then with making the image, they also suggest unmounting the destination disk before trying to restore but my destination is Macintosh HD, i cant really unmount that can i?
    Thanks in advance!

    To make a clone, in the future you need to use a program like superduper or carbon copy cloner.
    Either program makes an identical clone while preserving certain system files and marking/indicating to OS X that the clone is bootable.
    Using Disk Utility to make a DMG was a good idea, but this will not yield a bootable image.
    If Disk Utility could do a 1:1 copy of everything, then people would be using it to rip/duplicate DVDs.
    But Disk Utility does not (it leaves out certain invisible/system files), hence it cannot duplicate/clone a hard drive or DVD.
