Snow upgrade & raid sets?

I am just about ready to upgrade my system to snow and was wondering if anyone else uses the mirrored raid config for backup drives? My question is what will happen to the raid set when I upgrade the OS? Having to rebuild it is a major pain in the *** and takes forever! I've had to find that out the hard way and learned its actually quicker to just copy all the data to a temp drive - rebuild the raid set from scratch - and then just copy back over all the data. But even that can take a very long time too. So will snow honor any existing raid sets on external drives or would it just be better for me to use the built-in time machine backup system?

I see what you mean, but I don't use my backup drives as a cloned bootable. I have another user on my system and therefore have it setup without permissions. Too many file permission issues for the other user if I don't! So I just use it for saving photos, docs, and other items I don't want to lose. The thing I love about RAID is once you set one up, that's it! All the cloning or mirroring is done automatically to the extra drive. With most other backup software I've used, you have to usually schedule a backup time which doesn't always work if the Mac is asleep or if you are logged out before the set time. So with a RAID, at least I know every single time something new is saved, it is immediately copied at the same exact time to the other drive as well.
So I don't know what you mean by unreliable? Shouldn't that be the perfect job for any backup system? To immediately clone one drive to another without delay? But my original question was about whether or not upgrading the OS would honor or maintain existing RAID sets. Instead of having to rebuild them.

  • Upgrading Xserve with RAID set

    Hi,
    I have been asked to upgrade a copy of Server 10.3 to 10.4. I don't like upgrading, so will do a clean install and then restore all of the SA and WGM data back into the server. Here is the question:
    The XServe has 3 bays - bay 1 has the startup disk and bay 2 and 3 have a mirrored RAID set. Is the RAID config data held in the OS, so if I reinstall the system will the configuration data for the RAID set be lost and will I have to re-RAID the server? Or is the config data stored on the drive and so a re-install won't affect the RAID set?
    Many thanks,

    I would like to know if the RAID 'config' data is
    actually written onto the drive or is stored in the
    OS. I first thought it would be stored in software
    because Disk Utility uses software RAID, but then
    again a single drive has the partition data on the
    drive.
    James,
    If you think about it a bit, software RAID information has to be on the drive because the volume becomes a RAID before a filesystem is created and before an install is done. Likewise, a hardware raid is done on the interface card and comes up the same way. Neither can know which of the members of the mirror are available at first boot; otherwise, there would be a single point of failure during boot, and the whole purpose of a RAID 1 mirror would be lost.
    The bootstrap starts on the mirror primary, then, as the driver is brought online and before any writes are done, the driver collects the members of the RAID 1 mirror set and forms the mirror. If the mirror primary isn't available, then the mirror secondary is used (which has an exact copy except for stuff indicating that it is the secondary). All this happens normally during boot, as if from a single non-RAID drive, until the cutover is made to RAID early in the driver intialization.
    That's why booting from a RAID 0 (stripe) is so hard - all of the data is not present on a single drive. It can be done, but it is hard and requires special care during the boot.
    You really do want to make the upgrade to AppleRAID 2 before spending time on the update, though. There are details in this article on afp548.com:

  • Macbook Pro with Dual hard drives. Scratch Disk, Memory 64bit, Raid, Set Up Questions.

    Hello, this is my first post.
    I just upgraded from the original 2006 17" Macbook Pro to a refurbished 13" Macbook Pro 2.53GHZ 4GB Ram (2009 model).
    I bought the MCE Tech Optibay and installed it (if you dont know anything about it, ask me, its amazing.) So now I have 2x 500GB 7200RPM Seagate hard drives installed.
    I am running Snow Leopard, CS3, Lightroom 1.4.
    I have the main hard drive set up with Snow Leopard and all the Applications. I keep all my files on external firewire 800 drives, except files I am currently working on.
    The second hard drive is set up as a scratch disk for Photoshop CS3 and that is it.
    I am looking to upgrade to CS5 and Lightroom 3 here within this month or so. Or if I get anxious, tomorrow, haha.
    I want to know the best setup I can do with my current set up with CS3 and for my future setup with CS5.
    Any info will appreciated.
    -Would some kind of raid set up with my internal drives be better? How does raid work with scratch disks?
    -If I upgrade to 8GB memory in my macbook pro, would I even see a difference in performance if I didn't have a scratch disk? Since CS5 and Snow Leopard can use more memory in 64bit.
    I think thats all I have on my brain right now. I may have more questions, or I can guarantee I will have more later.
    Thanks alot.

    First the scratch. Like you said, most everyone has a different take on scratch discs but I'd guess you're wasting one heck of a lot of hard drive space using all 500 GB for Scratch, did I read that right? If I did read it correctly YES, partition it and get some use out of it!!
    I've got a unibody MBP 2.93GHz, OS 10.5.8, CS3 & PS 5 (running in 32bit mode), and 8 gigs of ram. I've partitioned the one 300 GB drive so 50GB is scratch, the other partition is for OS, & Apps, and documents (images).
    I use LR 2 first than export to PS 5 to finish up. My photos get to be 300MB to 500MB in size and both versions of PS work on this setup just fine. Using PS 5 in 64 bit mode is faster opening files but NON of my plugin's are 64 bit yet, that's why I'm still stuck in 32 bit mode.
    Not knowing what size or kind of files you work on makes giving advice a bit tough but try setting the status indicator (don't know the right name for it) in the bottom left corner of any PS open file to "Efficiency" and watch what happens when you process your files. I rarely see mine drop below 90%, I've got the usable RAM in PS Prefs set to it's max suggested, cut way back on History and Cache.
    Can't wait for NIK and others to offer their plugin in 64 bit, later this year is what I was told.
    There used to be an old "rule of thumb" with old version of PS about Scratch disc size. I don't remember exactly but it may have been 3 to 5 times the size of your biggest file??
    Good luck, Alan

  • Mac Pro 2009 Raid Set Lost after Hard Reboot

    We have a newer Nehalem based Mac Pro with a 2009 Black Apple Hardware Raid card.  The Hard Drive Configuration is: 4 x 2TB Western Digital drives setup as a Raid 1+0 array providing 4TB of space with what we believed to be optimal performance and redundancy.  We had two volumes / partitions configured on the array, one 120GB for the OS and the remaining 3.8TB for data. 
    Everything was working fine when the server froze up.  ON the Screen an error message said there is a problem with your Raid controller, Please open Apple Raid Utility.. Unfortunatly when we tried to do that we just got a spining beachball. We tried to open finder and it beachballed.  We tried to force quit and nothing working. Finally we were left with no choice but to do a hard restart of the server and turn the machine off and then back on. 
    When the server came back on it would not boot up.  We were greeting with the Folder with a Queston Mark.  We booted from the Mac 10.6 Snow leopard Server Disk and opened up Apples Raid utility software.  Much to our shock the Raid Set and the two Volumes were not shown in the Utility.  However all 4 of the drives were listed and all being shown as Green light good status, but listed as "Roaming".  We weren't sure what to do, the volumes weren't accesible since they didn't exist, the Raid set wasn't there, there was no way to run something like Data Rescue Recovery software.  We tried calling Apple and have to wait until they open this morning.  After looking online at various forums we came accross this problem with no solutions.  Most of the people with the problems had the older 2006 Blue Raid card, and this appeared to be a common issue amoung others with the older card.  I decided to try and re-create the Raid 1+0 set.  However as soon as I did that I was prompted by Raid Utility that the drives I was selecting to use for the Raid set were already a part of another raid set and using them would delete the data on the set.  I obviously canceled the process. Crazy enough the system knows the drives belong to a Raid set but doesn't realize it should know what the raid set information is.
    We were using Mac OS 10.6.7 Snow Leopard Server, and I even tried installing and updating an external drive with 10.6.7 Server and booted from the drive from the machine and try to run Raid Utility.  That did not work either.  Any advice from anyone would be awesome.  I'm worried what Apple is going to say when I do get a hold of them, the system is under Apple Care warranty.  Thanks in advance for anyone's time.

    I haven't lost data, but in my 2010 Mac Pro with 2009-vintage Apple RAID card, it has this Really Annoying Habit of constantly losing Disk 3 (the spare) in my 4x2 TB internal RAID5 array whenever I have to do a hard reboot.
    I keep having to re-mark the now-"Roaming" drive as a Spare and then wait 8+ hours for it to rebuild the array ... grrr.
    I saw an Apple KB article that suggests removing the Roaming disk and re-inserting it.  Duh.  Fat lot of good that did.  Really wish there was some answer to this issue ... hard reboots should NOT cause array disks to go from "Assigned"/good to "Roaming"! 

  • OSX Server RAID Set-Up

    I have a Mac Pro running OSX Server 10.5.8. A RAID was set-up initially, but I have upgraded to larger hard drives. I used SuperDuper to clone the start-up disk (including all files and applications). This went great. All works perfectly.
    But now, I want to install the second drive (brand new) and set-up the mirror RAID.
    My question is, when I use Disk Utility and add both drives to the new RAID, will it automatically copy/duplicate the start-up disk to the new drive? Do I use SuperDuper again for the new drive, then set up the RAID?
    How do I ensure the integrity of the data on the start-up drive during the process of setting up the RAID?
    Thanks.

    Ordinarily, when you use Disk Utility to create a mirror, it's going to throw away the current data, so you'll start with a blank slate.
    Given that you have a working SuperDuper clone of your system, the logical step would seem to be to update your clone, create your RAID set, then restore your system from the clone to the new mirror volume.

  • C200 M2 forgets SW RAID Setting

    Hello Folks,
    I'm using the SW Raid feature of an C200 M2 Server. It works well, but if the server is disconnected from power for some hours it "forgets" the SW RAID Setting and boot order in the BIOS, defaults back to Enhanced mode. BIOS and CIMC Firmware are in actual SW state (updated with the
    ucs-c200-huu-1.4.2.iso ) Is there any solution for this problem?
    Thanks
    Bernhard Dick

    Hello Padma,
    there is no additional controller card, I'm only using the integrated Software RAID, the boot configuration consists only of the Raid volume. And it matches the shown configuration within the CIMC.
    I could reproduce it the last three times I had disconnected power for about 10 hours, last switch on after ~6 hours w/o power everything went fine. During the week the system sits in a production environment, I'll go and check if I can reproduce it again with >= 10 hours without power next weekend.
    I did the update all selection in the Host Upgrade Utility.

  • Why a Apple RAID controller card cannot delete a RAID set?

    Hi,
    I just have a problem with my RAID set created with RAID Utility.  My configuration is as follows:
         Mac Pro (early 2009 model) 2 x 2.66GHx Quad-Core, 16GB DDR3 1066Mhz Memory
         Apple RAID Card (HW Ver 2.00 and FW Ver E-1.3.20)

         3 x 2TB HD (WD black series RE) in Bay 2 to Bay 4 configured as RAID 5
         Mac OS 10.7.4
    The RAID Utility showed the following messages:
    Degraded RAID set RS2 - No spare available for rebuild
    Degraded RAID set RS2 - No spare available for rebuild

    It also showed "Severe Events" message:  "Degraded RAID set RS2 - No spare available for rebuild."
    I tried to delete the RAID set using Apple RAID Utility but nothing happened.  Can anyone help as I have to rebuild the RAID set from scratch?  Thanks.

    I have swapped the drives in bays and it is always bay 2. I'm coming to the conclusion that either the RAID card is failing in bay 2 or there is a Lion / Mountain Lion issue with the RAID card.
    I would say this is not "a Lion / Mountain Lion issue with the RAID card", as I have an "Early 2009 Mac Pro" that is running Snow Leopard (10.6.8), fully patched, that is exhibiting a similar issue, after about 4 years of no such problems.
    My RAID configuration is just like yours: 4x 2TB drives, with Bays 1 & 2 as RAID 1 and Bays 3 & 4 also as RAID 1.  I keep losing either Bay 1 or Bay 2 disk, and after reboot typically see it as a good disk, in the green, but now unassigned to a RAID set, and marked as "Roaming".  When I assign it as a spare, so far the RS1 RAID Set begins to rebuild, and things are okay for a short while.
    Initially this happened about once a month, starting about 3 months ago, now it is a weekly or several times weekly event.
    I've put in new disks (several), restored from a Time Machine backup, and just came in today to find the Bay 2 disk "Roaming".....
    I'm going to try a new Mac Pro RAID card, as I have a spare - just looking for information about whether the replacement RAID card will pick up the RAID sets from info cached on the disks (I hope!), or whether I have to newly create the RAID Sets & Volumes, and then re-populate from Time Machine / the old disks.
    I will say that I've been running 8  "Early 2008 Mac Pro" computers with RAID cards, each configured as above, and 4 "Early 2009 Mac Pro" computers similarly configured. These were all deployed between late 2008 and the beginning of 2010.  I've had little difficulty with them, and they've been wonderful when an actual disk failure has occurred.  I've had about 6 actual disk failures among all these setups.
    cheers!

  • Vista won't install on a RAID set. ***SOLVED***

    I just installed my new MSI 790GX-G65 system and I cannot install Vista (32-bit) on any type of 2 disk RAID set that I have tried to create.  I can get the installer to see the drive(s) by loading the driver, but after partitioning and formatting, I get a message about "windows cannot find a valid drive for install" or something to that effect.  I can install fine using IDE mode and just picking one of the drives.  Any help would be appreciated.

    Quote from: FrogmanTM on 09-August-09, 05:39:36
    Well, I solved it!  The problem was with the Vista installation process itself.  It turns out that Windows reads information about the boot sequence from the BIOS of the motherboard. It looks at this information to understand what will happen when the system boots for the first time. If you have a USB drive connected to the system and it is listed in the boot config as a bootable device (in my case the BIOS put the USB stick as the second boot device, right after the CD drive, and the RAID volume was listed AFTER the USB stick) - you will probably see this error: "Windows could not determine if this computer contains a valid system volume."
    To get past it, I had to re-configure the BIOS Boot options to NOT include my USB drive as a bootable device (or just drop the priority below whatever drive you will be booting from). You can also boot your system without a USB drive installed - not an option for me since I need to install 3rd party raid drivers.
    Whew!  Thanx for all your help, I am glad I finally figured it out.
    Wow dude you're a genius for two days I've been searching and searching and searching wondering why my vista wont install onto my raid 0.  I have a DFI board with a 760fx chipset, i have done all the bios updates and brand new raid drivers and to no avail.  Found this post and voila.  Thanks a lot.  Such a simple fix usually the last thing you think of or not think of it at all.

  • Mac Pro (2009) RAID Card - Can't create RAID Set

    Hi Everyone,
    I have a Mac Pro 4,1 (Model 2009) running Mavericks 10.9.2. with the Apple RAID Card installed. I got 4 new SAS Drives (Dell Toshiba MK2001TRKB) which I'm trying to configure into a single RAID5 set.
    OS X detects the individual drives and with Disk Utility I can partition and/or format the individual drives. However when I try to create a RAID5 set using RAID Utility, the card won't create the RAID set. Ik keeps on showing the white-blue stripped progress bar. Tried creating a RAID0 or RAID1 with just 2 drives, but the card just doesn't create a RAID set.
    Anyone got a clue why this isn't working?
    Thanks,
    Sander

    Manualy erased all 4 the drives and it worked instantly. System is now initializing the volume :-)
    Still a bit strange. All 4 the drivers where brand new. I did some further testing and if I select the partion tab and just create a new partition on each drive, it still doesn't work. I have to select the erase option in Disk Utility and just do a simple erase on each drive in order to be able to create the RAIDset.
    Anyway, Thanks for the advise; performance even during initializing is pretty fast. I'm curious to see what kind of performance I get aftet the initialization is completed.

  • Advice on RAID Sets, Volume Sets, and RAID Levels of the Volume Sets using an Areca Controller

    I have read through a lot of information on disk usage, storage rules for an editing rig, users inquiries/member responses in this forum and I thank each and every one of you – especially Harm.
    In building my new workstation, I purchased five (5) WD 1T, 7k, 64M SATAIII hard drives and an Areca RAID card, ARC-1880ix-16-4G, which I plan to use primarily as my media/data disk array.  The workstation will use a 128GB SATAIII SSD as the OS/program drive and I will transfer two (2) WD Raptor/10k SATA 70GB drives from my current system for pagefile/scratch/render use.  I tentatively plan on using a mobo SATAIII port for the SSD and mobo SATA ports with a software RAID (level 0) for the 10k Raptors.
    In reading the Areca Instruction manual, I am now considering exactly how I should configure the 5 physical 1TB drives in terms of RAID Level(s), Volume Sets, and RAID Sets.  I must admit that I like the opportunity of allowing for a Dedicated Hot Spare as I am generally distrustful of the MTBF data that drive vendors tout and have the bad experience in the past of losing data from a mal-configured RAID array and a single drive hardware failure (admittedly, my fault!).
    In line with the logic that one doesn’t want to perform disk reading while trying to write at the same time (or vice-versa), I am thinking the approach above should work OK in using the mobo disk interface and both software and external hardware RAID controllers without having to create separate RAID level configurations within a Volume Set or further dividing up the physical drives into separate RAID sets.  I know in forum messages that Harm noted that he had 17 drives and I could envision a benefit to having separate RAID sets in that situation, but I am not at that point yet. 
    To some degree I think it might be best to just create one RAID Level on one Volume Set on one RAID Set, but want to solicit thoughts from veteran controller users on their workflows/thoughts in these regards.
    Anyone care to share thoughts/perspectives?  Thanks
    Bill

    Thanks for the speedy feedback Harm - I appreciate it.
    I was thinking RAID level 3 as well.
    Of course, it's always something!   I purchased the Caviar Blacks by mistake - which are non-TLER.   I will work with EggHead to return the ones I purchased and replace them with RE4 versions  as I'm not thrilled about the possibility of the controller declaring the volume/disks degraded unnecessarily and although I have the DOS utility WDTLER where one is supposed to be able to enable/disable TLER on WD drives  - I suspect WD is way beyond that now anyway with current builds.
    I agree with you about just testing the performance of the options for the raptors - on the mobo and then on the controller.  When I benchmark them I'll post the results in case others are curious.
    Thanks again....off to EggHead!

  • Creating a mirrored raid set with a hard drive that already has data on it.

    I have a hard drive that I keep my photos on, and want to create a mirrored raid set that includes this drive, with its data, and another drive.  How can I do this without erasing the drive with my photos on them?  I am running 10.7.5 if that matters.
    Thanks for any help.

    Creating a Mirrored RAID reformats the drive and loads a substantial RAID driver and some tables onto it. When completed, the drive is inherently a member of a RAID set, and will continue to be so even if moved to another Mac.
    because of this, you cannot create a RAID directly on a standard drive that contains data already in any reasonable, risk-free way.
    To amplify what The Hatter has said above, Mirrored RAID is not Backup. Mirrored RAID only increases mean time to repair to keep a drive failure from becoming a Data Disaster. You still need a Backup. Mirrored RAID does not protect you from deletions from user error, crazy software, or "just because".
    I run a mirrored RAID in my Home Server, which contains all the Users files for everyone in the Household. And I also recognize (after being burned by it) that Mirrored RAID is helpful, but not a sufficient Backup by itself. I back up the Users Drive automatically to an External drive using Time Machine. [So what I am advising is not just theoretical, I am living what I am advising.]
    With WD Black 1TB  and other very good drives in the under US$100 range, there is really no reason NOT to invest in several drives for such an undertaking.

  • How can I temporarily remove a RAID set but keep the data?

    I recently had to restore my Netgear ReadyNAS to factory settings, which meant that I needed to make a backup of its data and restore it afterwards. The only possible way to back up the 8.5Tb of data was to get 9Tb of WD Red disks and somehow use them - so my immediate thought was that the Mac Pro would be a good idea. I t had four drives in it, but three of them were not being used by the OS so they could be temporarily removed.
    So I replaced three of my four Mac Pro drives with new 3Tb drives and used Disk Utility to set them up as a JBOD. I then used this JBOD drive to back up the NAS and restore it again after I had re-installed its O/S (the whole thing took two weeks!!!).
    So now I'm in the following situation:
    * I want to tear down the JBOD set and take the three new drives out of the Mac Pro again and replace them with the drives I normally use there so that I can go back to making music (which is what I usually use it for).
    * I also want to be able to put the new drives back in and read the data as a JBOD again if needed (in case anything is discovered to be amiss with my ReadyNAS backup/restore operation) - let's say for the next month I'll plan to keep the old drives around for safety.
    How can I remove the JBOD set in such a way that I can set it up again using the same drives, and access the data (i.e. I don't want to delete the RAID set the usual way because that will delete the data too - apparently...)?

    Going to ask the mods to move this to MacPro, Hatter can answer your question, but I'm pretty sure if you power down and remove the RAID drives, you can put them in back again and boot up and the RAID will still be recognized as the info is stored on the drives themselves in the GUID/MBR of each drive in the set.
    Also you should know, there is a new MacPro coming and it doesn't accept internal drives, only external.
    So you should prepare and have some sort of external hardware redundancy for your data that isn't dependent on the Mac HFS+ formatting as Windows doesn't read that.
    Perhaps exFAT would be better as both platforms can read/write that, but if the drives are going to be used with a PC ever, they need to be formatted by Windows for exFAT to get it right. Check first before you commit to copying huge data over.
    Anyway research it, because if your MacPro dies, you might be up the creek and have some issues getting at all that data since it's in a RAID, external options might not work correctly or reliably for RAID.
    Also consider talking to the fellows at MacGuru's, they are external RAID box setup experts for Mac's, sounds like you need a RAID 5 box, gives redundancy and can connect to any computer.
    Hardware RAID is more reliable than software ones, cross platform as well.
    good luck.

  • RAID Sets:

    What are RAID sets?????????????
    I want to use them if they are what I think they are. Automatic synchronization of volumes???????????????????
    Am I Correct???????????????????????
    How do I begin??????????????
    And is it possible for volumes from two different Hard Drives to be part of the Raid Set??????????????????????????

    A RAID is only really beneficial if the drives being used are internal drive on a fast bus, such as in a Mac Pro or Power Mac.
    The only way to do it with an iMac G3 is to string a few external drives from the FireWire port (or get one of those enclosures that house multiple drives). Because modern single drives already exceed the speed of the FireWire connection, having a RAID connected to FireWire will not significantly increase data transfer rates. Also, modern single drives can now go as high as 2TB, so the other RAID benefit of creating a large volume is also negated. As for data redundancy, it may be beneficial to be able to sway drives without downtime, but it is not that useful in a desktop (client) machine. Using a single drive is simpler and more reliable, with backups to a separate single drive.

  • RAID Set not showing up - 3 severe events

    Intelle Xserve running 10.6 RAID Card running firmware v E-1.3.2.0, Two it drives set up with I think RAID 5.
    The main person for the  system is away as well as his backup. So I'm running on very little information at the moment.

    Could not connect. After trying all that I could, powered down the server. Restarted, got a login startup permissions error for an item to run at startup. (I'll have to check what exactly that was). Started the Portfolia server and the FileMakerpro databases. Users able to access and use.
    Next day same thing. User lost connection with the server. Restarted, start filemakerpro databases and portfoilio services. User able to access.

    The drive shows up on the desktop but when I go into the drive the folders etc are showing. Access the main folder results in a loop where it bails out and just shows the desktop again.
    I'm going to get some files to the user from the timemachine backup for now.
    Is it possible that the data is OK and maybe the drive are marked off line for the set but still OK?
    Any info would be great,
    Thanks

    Yes the 160GB has the OS. I'm coming into this cold as the main person and the backup are currently away.
    I have got the users a work around so they can do thier work. The backup person has very limited email contact and he had thought it was a RAID 5.B  But I would agree this looks to be a RAID 0 or 1 since there are only two drive available for data.
