Need input on-partitioning 4TB G-Raid.

Have G-Raid 4TB Thunderbolt drive with Time Machine already on it. My iMac 27" has a1 TB fusion Drive. I would like to partition G-Raid for data too. Need ideas and how to. Also will Time Machine backup both drives. Thanks

Thanks, I don't really the space for data right now but if I put data on it will Time Machine back it up. I am thinking about my Aperture Lib. and thought they would be faster with Thunderbolt but the Fusion Drive is pretty fast. I just got the iMac moved old iMac ( 2008) and Firewire. Have about 650G on Fusion Drive. Just looking for best performance. Thanks

  • Mirro Raid can you use a single 4TB disk with 2 partitions for mirrored raid ?

    Hello,
    I have a new 4TB hardrive.
    After lots of reading, i was thinking that i could partician the drive to 2 (2TB) Then create mirror raid.
    Essentially thinking that i would have photos on one of the (2TB particions) and they would mirror on the other  ?? as a double copy storage.
    I can partician okay and the try to drag the two particians onto the "mirror raid set" and ithe following message displays :
    "Can't add Seagate expansion disk" to the raid set because another volume from this disk is already part of the RAID set"
    I'm now thinking i need to purchase another 4tb hardrive for this to work ?
    Or if you "mirror raid set" is it actually particioning the drive and creating a copy ?
    Forgive me... i'm not really very up skilled with disk utility, and basically just don't understand.
    Looking forward to some help and advise
    warm regards Tracy Gr

    It doesn't make any sense to mirror on the same drive. The idea behind mirroring is that should one disk in the raid set fail your data is safe on the other disk. Mirroring to partitions, if it's even possible, would only bring you disaster when the drive fails because you would lose the complete raid set and all of your data. If you insist on mirroring buy another drive.

    BIOS: AMI V1.1 (11/07/2007)
    Hello,
    Almost all new motherboards today only have a primary ide channel and the rest are SATA.
    I need inputs regarding the dvd drive which is shown in device manager as located on the primary ide channel while the hard drive is located on the secondary channel. Because I would like to update the dvd drive to the latest firmware (version 1.06; to be able to recognize more blank media) but the LG site recommends that the drive (dvd) be located on the secondary ide channel.
    I already tried to uninstall every channel from the device manager but all would still be the same after reboot, dvd drive on primary, hard drive on secondary.
    Current ide mode in BIOS is set to AHCI+IDE mode, DMA modes are fine (UDMA4 for dvd, UDMA5 for hard drive), boot sequence (1st=HD, 2nd=DVD, 3rd=Floppy drive)
    Tried switching to IDE mode only in BIOS but would not detect the optical drive. Never tried RAID+IDE mode since I only have a single hard drive.
    I'm not sure but if I try to update the firmware, it might instead try to update the hard drive's firmware instead of the optical drive and make the hard drive unusable.
    I would like to know if anybody with this same situation was able to successfully update the optical drive's firmware or is there some way to place the optical drive on the secondary ide channel and the hard drive on primary for me to follow and replicate the process.
    Thank you for any replies.

    Thanks sir NovJoe for the reply.
    Just received the solution from another forum where I posted the same problem.
    They said that the flash program for the firmware will detect the drive on its own and would not flash other devices except the optical drive itself. So its pretty safe, and I can confirm this since I just flashed my ODD a little over a while ago and everything went fine. No errors.
    Though I'm speaking for the brand of ODD I own and may be different for other brands so take precautions as well. It may be different for the others.

  • Unable to set Non-FS partition type (GPT + RAID)

    I'm performing a new install, and am following the RAID wiki for a RAID1 on 2 disks.
    The wiki suggests to use the "Non-FS" partition type (DA00), rather than the "Linux RAID" partition type (FD00), to avoid potential issues down the road.
    However, the example given in the wiki is for cfdisk (MBR). I'm using GPT partitioning rather than MBR, and cgdisk only accepts the FD00 partition type, not DA00.
    Do the wiki's precautions against using FD00 only apply to MBR-partitioned drives? Or should I be setting the partition type some other way?

    A few comments:
    Four-digit (two-byte hexadecimal) partition type codes are, AFAIK, unique to my GPT fdisk (gdisk, sgdisk, and cgdisk) program and any programs that might mimic it. (The fdisk clone in busybox is one of these, IIRC.) These codes are not industry-standard; I created them just because I needed a compact way to describe partition types and to accept partition typing data from users. GPT actually uses 16-byte GUIDs as type codes, and those are very awkward, from a user interface perspective!
    GPT fdisk does not have a type code of "DA00," so any documentation that refers to such a code is either flawed or is referring to something other than my GPT fdisk. (Somebody might have a patched version of GPT fdisk that implements such a code, though.)
    AFAIK, there's no such thing as a generic "non-FS" partition type for GPT. The most complete list of GPT type codes I'm aware of is on the Wikipedia entry on GPT, and I don't see anything close to that meaning in its table.
    According to this site, which holds a good list of known MBR type codes, 0xDA is the MBR type code for "non-FS data." Given the way I create GPT fdisk type codes, that would translate to DA00 if there were a GPT equivalent. Since there is no GPT equivalent, though, DA00 remains invalid in GPT fdisk.
    Tools based on libparted, such as parted and GParted, do a terrible job at presenting partition type code data to users. I've just skimmed it, but the page to which you refer, s1ln7m4s7r, appears to set up RAID data on a partition with a GUID of EBD0A0A2-B9E5-4433-87C0-68B6B72699C7 -- "Microsoft Basic Data". That is, the RAID partition will be flagged as holding an NTFS or FAT filesystem! That's one of the worst possible ways to set up a Linux RAID, in terms of its partition type  code.
    For the most part, Linux doesn't care about type codes, on either MBR or GPT. There are a few exceptions to this rule, though. Thus, on a Linux-only system, using a bad partition type code won't have dire consequences; but on a dual-boot system, or if the disk gets moved to another computer for some reason, a bad type code choice could result in data loss. Windows might try to reformat the partition to use NTFS, for instance.
    The Linux RAID partition type code (GUID A19D880F-05FC-4D3B-A006-743F0F84911E on GPT; represented in GPT fdisk as FD00) was created to hold RAID data. Although I do recall running across advice somewhere to not use this type code for RAID data, I honestly don't recall what the reason was, but my recollection is that I was unimpressed.
    Since you didn't post a link to the page that recommended using "DA00" for RAID devices, Nairou, I can't comment on that advice in context; however, I suspect the author was confused or that the wiki went through some edits and something got mangled. Unless somebody can provide a good reason otherwise, I recommend using the RAID data type code on a partition that holds RAID data. If you want to use something else, create your own random GUID; do not use the type code for a Microsoft filesystem, especially if the computer dual-boots with Windows!

  • Can I add partitions on a RAID 0 setup?

    Hi everyone,
    I just recently bought a used macbook pro, (15-Inch, Early 2008) that the previous owner put a RAID 0 setup on. I want to try out the OSX Yosemite Beta, but i want to try it on a separate partition so I can keep my Mavericks environment intact. I don't know i it is possible, but I would like some help on how to make a partition with the RAID setup on it. (I do have an external hard drive too, is there a way to run Yosemite off of the external instead of messing with the internal on my MBP?) Thanks in advance for your help!!!

    This doesn't sound like an XServe RAID question - the XServe RAID is a (now-discontinued) 14-drive RAID enclosure designed for server applications.
    I apologize for not knowing where. I know how forum members get upset when people use the wrong forum. It was unintentional.
    For a start there's a question of the enclosure... Is the enclosure a 'dumb' enclosure that just connects the drives to your host system, or does it have a built-in RAID controller.
    It is not a dumb enclosure - it does have jumpers for setting it up under different strategies.
    That is going to be critical in answering your question. If the enclosure has a built-in RAID controller then you will want to use that to manage the RAID 1 mirror setup and you'll likely need to use software provided by the enclosure vendor to set that up.
    Where I am at is that DU does NOT allow this system to be used and recognized by TC. I had to set the enclosure under RAID 1 and that is the only way the TC would allow it to be recognized by my network
    Once that's done your host system will be presented with a 1TB volume (the RAID/mirror is hidden from the OS) and you can partition that like any other drive.
    If the enclosure is dumb it's a little more complex since you'll need to configure the mirror via Disk Utility and then partition the resulting volume (note also that throughput will be lower in this mode since the OS has to write twice as much data over the link to the enclosure - with a hardware RAID in the enclosure the OS only has to write one copy of the data and the enclosure takes care of writing it to both disks).
    So, what's the enclosure you're using?
    I am using the Hornettek unit.
    Thanks for your help. It took me a long time to get to where I am with this unit. TC evidently will not allow it to be recognized if I used DU to configure it.

  • Partitioning a Hardware RAID

    OK, I have already searched the net to no avail, im hoping someone here will be able to help me.
    I currently have an external 300gb HD with 2 partitions, one is a bootable backup and the other is storage. I have recently realized that if this drive were to fail I would lose a ton of important data. I therefore have decided to create a raid setup. I am considering purchasing a Buffalo DriveStation Duo with 2 500GB drives in it. I would set this up in a RAID 1 array so I will have 500gb of usable space with a constant mirror image backup. My question is, can I partion the RAID into 2 partitions (as I have now with my 300 gb drive) one for a bootable backup and one for storage and still maintain the mirroring. In essence I want to have 1 drive with 2 partitions on it, and have the drive still be mirrored to the second drive.
    First-Is this possible?
    Second-Will I still be able to boot from the boot partition?
    Three-If so, can having more than one partition on a raid create problems, such as increased disk failure, slower speeds, etc?
    Thanks in advance to anyone that can help me with this!

    I'd say you want separate partitions for atleast /, /usr,/opt, and /var. Probably one for /home, too. I'd definately isolate the filessytem where all of the work will occur onto it's own partition to reduce fragmentation on the others.

    A couple of thoughts in no particular order.
    1. Read the FAQ and learn how to use { code } tags to post a readable listing
    2. Your version number is (all decimal points)
    3. Provide DDL for the table
    4. Provide INSERT statements with sample data
    5. This is horrifying
    START_TIME > '01-AUG-2011' Dates are dates ... not strings. Best case you have an implicit conversion ... worst case a statement that will return invalid results. Either change the data type or do an explicit cast with TO_DATE.

  • Need input on Approval Process via hand held devices

    Hi All,
    Need inputs on the given scenario. We have implemented Quotation Management (VA21) for our client. The quotation goes through various levels of approval (or decline) via the Workflow below it is finally given to the customer.
    Users usually logs into SAP and approves (or decline) the quotation via the SAP Inbox. We have designed multiple decision process on the work item in the inbox. Alternatively users can also log in to Enterprise portal, which has been designed for them, to act on the quotation. Users are notified in their outlook mail about action that needs to be taken on the quotation.
    Now user wants to have the decision process to be implemeted as such that they can take action (approve/reject) via hand held devices (viz Blackberry). We are using ECC 6 and also have Enterprise Portal EP 7EHP1. Owing to cost constraint, client cannot implement SAP CRM Solution.
    If anyone of you has implemented such methodolgies or have worked on such solutions request you to get back to me with details regards to the timelines and cost and the desired process.
    Regards,
    Jayant

    You could acquire software (e.g. 3i Mobile Workplace or similar) that could handle the decision processing with little effort.
    If you wish to build a solution then the time/cost will depend on the complexity of the task visualization. You can create a Java client or use a simple HTML based web app.
    The decision task can be visualized using a custom BSP or WebDynpro application. Communication with the BlackBerry could be via RIM push or you could just send an email with a link to your approval application.
    The app would need to reserve the workitem and then complete the decision using the appropriate SAP_WAPI* RFC's.
    Bear in mind that all the above assumes you are distributing the approval tasks within your corporate network supported by the BlackBerry Enterprise Server and MDS.
    One of the bigger issues when using web apps is authentication. By default a web app requires the user to log on using their SAP user ID and password. Using a network user ID and password or using silent authentication is possible but requires more effort.

  • [Solved] Do I need a swap partition /swap file?

    Hello Arch Community.
    I want to install Arch Linux on my Aspire V5-573G Notebook with 8GB RAM and a 120GB 840 Evo SSD from Samsung. So my question is, do I actually need a swap partition / swap file? I read the arch-wiki pages about swap and suspend-to-disk / suspend-to-ram, and the only thing thats obviously profiting from / needing a swap partition is suspend-to-disk, no other things are mentioned in this regard. Is a swap partition in any other way important?
    Thanks in advance.

    No. The OOM killer is pretty darn tweaked these days and usually(!) kills the actual perpetrator. The alternative—disabling memory overcommitting and answering memory requests with an out-of-memory error—can result in unforeseen problems as well: What if it  a system process is trying to allocate a few bytes for some random string, and what if said system process isn't equipped to handle ENOMEM gracefully and crashes, because the default policy on Linux is to overcommit and never answer with out-of-memory errors?
    Just trying to play devil's advocate here. I'm not happy with the OOM killer either and I'd rather have a deterministic solution to out-of-memory situations, but I realize that it's probably not an easy problem to solve.

  • Need input on RAID 1 configuration

    Hi There
    I'm looking for an external storage bay to plug into my iMac, to back up, up to 3TB of data
    I'd like to be in a RAID 1 configuration that mirrors one drive to another - ideally reasonably priced, and with seamless Mac integration.  This was a recommendation from a friend, so I would like it to be ‘easy’ plug-and-play style with minimal configuration.
    Any suggestions? All the devices I’m looking at on Amazon seem to have quite bad ratings.
    Thanks in advance!

    Per the Mac Pro Memory Configuration chart:
    The 2x2 on the top riser should be in slots 1 and 2. The 2x1 on the top riser in slots 3 and 4.
    The 2x2 in the bottom riser is correct.
    I have this configuration and it works for me.

  • Xraid - raid volume backup procedure question, need input...

    If I have an xraid with two sets raid volumes, 2.5 TBs each, that I use for alternating backup. Am I eventually going to loose the fiber channel card, raid volumes, or xraid by switching out the raid volumes? I will have volume A in for a few weeks to a month then take out the drives/raid volume and put in volume B for about the same amount of time. I place the drives in the same spots/ side of the xraid. Each drive is labeled and place in the same spot each time. Everything has been working perfectly for a couple years but recently an apple specialist has told me that it's not a good idea. And that in time I am likely to damage/loose my fiber channel card, raid volume or xraid? That I am confusing the raid connection by changing drives.

    Actually, this all started with our xserve failing. The hardware and procedures I put in place worked perfectly. The xraid backup etc. Retrospect did it's job also. we were able to recover everything now I'm looking to improve our downtime and put a new xserve in place. Retrospect apparently worked because it was on the xraid. The recovery from firewire drives as a backup system is low and painful and can there's also a chance that you have to rebuild the retrospect file. The apple certified folks were impressed, no issues. And I don't power it down that often, once a month average, maybe. What I do want to implement in retrospect is a working backup. Not that we will work off of it but if that was in place then we'd be up and running sooner.

  • Need help with WinXP 64 and raid please...

    First off let me just say that for the past week or two I've been lurking on this forum while building my first 64 bit pc and I just want to say that all of your advice, suggestions, tips, and workarounds have proven to be invaluable. A sincere, heartfelt thanks to everyone here.   Like many of yours, my build has also been problematic. In fact, I guess I'd have to call it a pain in the ass. I can't imagine having done it without your help by using trial & error, so once again; thanks! Now, on to my ? My plan was to have one PATA 40gb HD to house 2 OS's on 2 partitions; a dual boot with XP and XP64, AND one RAID 0 made up of 2 160gb SATA HD's for everything else (actually the plan was to put the OS's on a Raptor but $$$). Now here's the prob: XP's up and running fine but when I try installing XP64 and it asks for the RAID drivers, it won't take them. It says they're not for a 64 bit OS. ? Am I the only one that thinks that odd? Isn't that the ultimate point of all this? So am I missing something? I d/l'd the 64 bit drivers from NVidia, is there a way to extract RAID drivers from them to a floppy? Also, I'd like both OS's to utilize the same RAID array for programs, storage etc. Is that a problem (my first time installing RAID   )? And if it WILL work, is it going to insist on wiping the drives and starting fresh? I hope not since since I've already got a ton of stuff on there. Anyway, thanks in advance for any and all help you might offer. Keep up the good work. -Glyph

    Thanks for your quick responses. So are you saying that if my OS isn't on the RAID array then I don't need the RAID drivers during setup? That's interesting. It's not how I understood it to be (not to say your wrong though). I'm pretty sure I needed them in WinXP, though it's on a different disc as well. Now that I think about it, maybe I could've waited and installed them through device manager with the same end result? I guess I'll try it and find out. And are there any ideas regarding the 2nd part of my question re data loss? I'd really hate to start from scratch at this point.

    Sorry I numbered them to show the flow of information, this was also just a place for me to store info as I worked through it. I managed to get it to work by creating a partition that takes up the whole drive and is actually 22 GB larger than all the other drives (since I found out that the had root, swap and home partitions that are no longer needed).
    I should be able to resize the other partitions without a problem, correct? They're EXT4. Should I unmount the raid array and do them individually, remount the array, let it sync and do the next? Or just unmount the array, resize all of them, mount it and let it sync?
