How Will Yosemite Logical Volume Group Affect Two-Partition Drive?

After installing Yosemite, my Macintosh HD became a Logical Volume Group. Now, in Disk Utility, both the Drive and the Volume have the same name — Macintosh HD. I want to use one of two partitions on an extra internal drive in my Mac Pro (Mid 2010) as a bootable clone of my Yosemite startup drive, using SuperDuper!. When cloning is complete, will my spare drive become a Logical Volume Group with a renamed drive? Will that effect the other partition, which is a bootable Mavericks clone?

Thanks for the tip. I see its a common trouble. But i stuck a problem that cannot be solved with this method cause i dont have revertable logic volume.
SO i cannot install system now. There's  no visible disk any more.

  • OSX Yosemite Logical Volume Group - FIX!

    Hey guys,
    For anyone wondering or concerned about why, when entering Disk Utility, the SSD name has been changed and you now see Macintosh HD and Macintosh HD below. The one above is listed as a Logical Volume Group with an "online" status while the one below that is your physical HDD (so normal as with previous OS's.
    I must note that I do not have any recovery partition when holding option when booting (after installing straight onto Mavericks, nor when making my own bootable copy).
    However, I did find a way to fix the Hard Drive name issue and revert it back to original format (I did find this fix online, and it has worked for me).
    I included pictures below as well.
    First one shows original Yosemite SSD name change (from Apple SSD to Macintosh HD with 18.9MB available)
    Second shows your normal HHD name unchanged.
    Go to Terminal and enter the following:
    diskutil cs list
    then you will see a bunch of volumes jump up
    enter: diskutil cs revert "UUID"
    under "UUID", enter the the Logical Volume code number without brackets.
    Do not copy and paste it from terminal into your new terminal line. Write it out.
    Hit enter and it will ask to reboot your Mac.
    Once, rebooted, your old SSD/HDD name with reappear as in Mavericks.
    My entire terminal line is shown in the picture attached.
    Either way (SSD name changed or reverted) did not changed how the system performed. Everything is running as it should.
    Final result shown in last picture!
    Hopefully this is just a bug that Apple will fix.
    Please ignore the DiskMaker drive (I was making a bootable copy on my external!!)

    Thanks for the tip. I see its a common trouble. But i stuck a problem that cannot be solved with this method cause i dont have revertable logic volume.

  • Failed to revert logical volume group while merging partition

    Hi All,
    Previously, on my macbook pro, I partitioned my disk for win7 for my dual operation system and only left 120 GB for OS, now I want to delete win7 and return disk space to OS. Currently my OS is yosemite.
    I have already deleted disk space for win7 and merged it back to disk0s3. And, I had a problem to merge disk0s2 with disk0s3.
    I was told it is because I need to revet my Logical Volume Group. I am blocked at reverting it.
    This is my disk info:

  • Logical Volume Group.

    My 1TB SSD main drive on my MBP Retina volume has changed to Logical Volume Group and the Partition is named Logical Partition.  Now it works fine but was wondering why it has changed from Mac OS Extended (Journaled).  If I want to partition the drive, it is grayed out with no options.  I'm not pleased that I can't control my own drive.  Any answers?

    FileVault is not activated, although it was at one point.  I deleted the partition and...
    I believe that may have caused the problem when I attempted to load the operating system on a new partition from the drive.  I deleted it and thought I reformatted it to Mac OS Extended, but I had major issues because it was locked at one point.  Just recently, I restored to a TM backup which should have formatted the drive correctly but this is what I ended up with.  Like I said, the option is grayed out now.

  • Error message when installing Yosemite OS: this core storage operation is not allowed on a sparse logical volume group

    I was updating my Macbook Air (i7, 4mb RAM, 256 gb) to Yosemite OS when the process was interrupted. After retry, my computer is showing the following message: "this core storage operation is not allowed on a sparse logical volume group". I tried to restart several times, but the problem goes on with error. It would be my computer damaged?

    If you don't already have a current backup of all data, back up before proceeding. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
    Start up in Recovery mode. When the OS X Utilities screen appears, select Disk Utility.
    In the Disk Utility window, select the icon of the startup volume from the list on the left. It will be nested below another disk icon, usually with the same name. Click the Unlock button in the toolbar. When prompted, enter the login password of a user authorized to unlock the volume, or the alternate decryption key that was generated when you activated FileVault.
    Then, from the menu bar, select
              File ▹ Turn Off Encryption
    Enter the password again.
    You can then restart as usual, if the system is working. Decryption will be completed in the background. It may take several hours, and during that time performance will be reduced.
    If you can't turn off encryption in Disk Utility because the menu item is grayed out, you'll have to erase the volume and then restore the data from a backup. Select the Erase tab, and then select
              Mac OS Extended (Journaled)
    from the Format menu.
    You can then quit to be returned to the main Recovery screen. Follow these instructions if you back up with Time Machine. If you use other backup software, follow its developer's instructions.
    Don't erase the volume unless you have at least two complete, independent backups. One is not enough to be safe.

  • Installing OS X Yosemite has changed my Macintosh HD type to Logical Volume Group

    I have just installed OS X 10.10 Yosemite on my late 2013 MacBook Pro with Retina Display,
    The installation has worked perfectly and my computer is now running fine. However after opening disk utility I have noticed where previously my HD would be named "Apple SSD...." and the partition underneath would be named Macintosh HD, both are now the same. Also, previously the HD was GUID type and now they have changed to Logical Volume Group and Logical Partition.
    I installed the software by creating a bootable memory stick with OS X 10.10 and completed a clean install by completely erasing the HD and then installing the new software. After the HD had been erased, Disk Utility still showed the HD as "Apple SSD...." with the partition "Macintosh HD" below and with Type: GUID. It wasn't until after the installation was complete and I had set up the computer and then gone back into Disk Utility when I released it had changed to both labels being "Macintosh HD" and the format type being Logical Volume Group and Logical Partition.
    I have no clue if this is normal and was a planned changed (i.e the software was designed to change it) or if my installation has gone horribly wrong. Can the HD format type be changed back or does Yosemite have to run on Logical Partition and Logical Volume Group formatted HD's.
    Any help would be appreciated as I'm not an expert and I have tried googling for hours and can't find anything helpful/useful or that will work.

    It's a designed change during the Yosemite install process. John Siracusa's excellent review of Yosemite over at Ars Technica provides some commentary on the change, specifically this page: http://arstechnica.com/apple/2014/10/os-x-10-10/2/

  • Can't delete a logical volume group created from a blank disk image

    Hi all,
    I'm a recent convert from Windows, so do bear with me while I grapple with all the new terminology.
    Basically, here's the problem: I've been trying to create an encrypted drive and have been at it for a few hours now. I ended up with two 'logical volume groups' created from blank disk images, neither of which are password-protected, and one of which I quite stupidly named "hidden folder" and can't rename now. Anyways, I decided to throw it all away and start right from scratch, but now disk utility won't let me delete these two logical volume groups despite me dismounting both devices, trying to trash the containing folder, etc. Some searching about online has gotten me into the belief that there should be an 'erase' tab in the disk utility window which is not showing up when I click on those drives (however, the erase tab does appear when I click on the indented partitions on each drive). Here's a screenshot to give you guys an idea:
    -Here's the disk utility window. The two drives I'm trying to get rid of are "Hidden Folder" and "HD2"
    -Here's what I suppose would be called the 'containing folder' in which both drives reside
    -And finally my setup, just in case it's relevant
    Oh and btw this would be my first post here! How exciting
    Thanks in advance,
    Arthur

    That is as it should be. If you select "Move to Trash" does it move the folders to the trash? If so, do the following from my previous post:

  • Reformatted Mac HD but it no longer has a Logical Volume Group

    Hi Guys,
    I've reformatted my Mac Pro's main HD, prior to doing a completely new install of Yosemite.
    Having reformatted it, I noticed that in the Disk Utility, there is no longer a main hard drive at the top of the list called Macintosh HD, with a Logical Partition (below it) also called Macintosh HD.
    Instead, the main hard drive is now called by it's SSD product name, which is 1 TB Apple SSD SM10... (etc). When I highlight it, the description in the bottom of the Disk Utility window is the same (1 TB Apple SSD...), whereas it used to be called Macintosh HD and its 'type' a Logical Volume Group.
    I have also noticed also that drive beneath it, Macintosh HD, is not referred to in the description as a Logical Partition now, whereas originally it was. (I've been able to make the above comparisons using my MacBook, which has never been formatted since purchase.)
    My questions are:
    - Is there a problem in not having a Logical Volume Group, but instead just having the hard drive specs as the name?
    - If this IS a problem, what is the best way to restore the drive so that I have a Logical Volume Group and a Logical Partition, both called Macintosh HD?
    If anyone can help me out with a layman's understanding of why reformatting my hard drive has set things up differently to the original configuration, and what the impacts are, I'd appreciate it!
    Cheers,
    Mike

  • Disk Utility formats Hard Drives as Logical Volume Group

    I just replaced a hard drive which had died in my Mac Pro which has OS X 10.9.5. To format the new 3TB hard drive I went to Disk Utility. I used "Erase" in its fastest form and the drive was formatted with the Type: Logical Volume Group.
    I remember this was a problem a few years ago when I first put hard drives in this computer. I think it was considered a bug in the Disk Utility in OS X 10.8 that it would automatically format drives greater than 2 TB as Logical Volume Group. The solution for me was to restart the computer with my OS X 10.6 disk and use the Disk Utility in that to reformat the drive. I never really understood why Logical Volume Group was a problem but I just obeyed what the wise ones of the Internet had to say.
    So, now I am wondering if I should reformat my new Hard Drive as GUID using my OS X 10.6 optical disk again? If it was a bug in the Disk Utility of OS X 10.8 then why is it not fixed in the Disk Utility of OS X 10.9? Is there an actual problem with having disks format formatted as Logical Volume Group? Is this now just Apple's way of doing things?
    Thank you.

    You could do your reformat using your 10.6 DVD. That's a decision that's up to you.
    Not every bug in a previous OS gets fixed in a new OS.
    I don't believe CoreStorage (Logical Volume Group) causes any sort of issues. Whenever one encrypts their Macintosh HD, the format is converted to CoreStorage. Fusion Drives are using CoreStorage and now Yosemite converts portables (laptops) to CoreStorage during the install process. As far as Yosemite is concerned, Apple seems to have gone the route of CoreStorage for portables. Even during the Setup on a portable, FileVault is offered with the default of YES being checked. So, if a customer isn't paying attention and continues with the install, they could encrypt their drive without knowing to uncheck the default checkbox.
    Thank you for your reply.
    I have decided to reformat my new hard drive using my 10.6 disk. I like being able to split it up into more than one volume if need be.
    I understand that not every bug in a previous OS gets fixed, but this strikes me as being really a very large bug, so I think it would be good if Apple addressed it.
    It is useful to know about Yosemite's behaviour. When I upgrade to Yosemite I will be a bit more prepared. In fact my MacBook Pro has FileVault on with Mavericks so Yosemite won't change anything there.

  • Can I Install Multiple Partitions in a Logical Volume Group

    I have a 3 TB Fusion Drive which is not partitioned and type is Logical Volume Group. In Disk Utility I have two tabs First Aid and Partition. In partition I can only divide it into two partitions is there anyway to change this so I can create more partitions?

    (Instructions for XP Pro and Acrobat 8.0)
    Open the printers folder and click on Add a printer.
    Click Next on the Welcome screen
    Select 'Local Printer attached to this computer', uncheck Automatically detect and install my Plug and Play printer, click Next
    Click on Create a new port, select 'Adobe PDF Port' from the list, click Next
    Select the folder you want the PDF stored in, click OK
    On the Install Printer Software screen click on Have Disk
    Click on the Browse button and browse to 'Program Files\Adobe\Acrobat 8.0\Acrobat\xtras\AdobePDF' (May be different for your setup)
    Select the AdobePDF.inf (English version) and click OK
    Select the Adobe PDF Convertor (there may be several listed, I always choose the top one) and click Next
    If the Use Existing Driver dialog is displayed select 'Keep existing driver' click Next
    Name the Printer i.e. Adobe PDF 1, click Next
    Set the sharing options, print a test page if you wish and finish.
    Now when you print to this printer from within an application it will create the PDF in the specified folder
    You can repeat this process for a number of outputs.
    Hope this helps

  • Logical Volume Group and Logical Partition not matching up in free space

    I was dual booting Windows 7 and Mountain Lion. Through Disk Utility, I removed the Windows 7 Partition and expanded the HFS+ partition to encompass the entire hard drive. However, the Logical Volume Group does not think that I have that extra free space. The main problem is that I cannot resize my partition. I am wanting to dual boot Ubuntu with this. Any ideas?

  • 3TB Fusion & logical volume group

    I'm in the process of fully reinstalling Mavericks - erasing my internal drive and paring my system way down, to resolve some long lingering issues.
    Disk Utility shows the recovery partition as separate (I've booted from it) - but when I went to erase the default Macintosh HD partition I was unable to repartition it as a single partition - it was grayed out - and the TYPE was/is logical volume group - where I was expecting to see GUID.   All I could do at that point was ERASE... which I did - so it remains a logical volume group -
    I'm unsure if, because of the Fusion drive, this is how they come from Apple - or the previous owner messed with it and trouble could loom wth this setup.
    It's a Late 2012 iMac with stock 3TB Fusion Drive.
    I'm in the process of reinstalling Mavericks from the Recovery (Internet recovery I'm guessing since it's taking 2 hours).  I'm not near an Apple Store unfortunately though do have extended 3 year warranty.
    Is it OK to leave the main Macintosh HD as "logical volume group"?????

    Yes. That's the technical name for what Apple marketing refers to as a "Fusion Drive." Don't change it.

  • I need to sudo cs delete an encrypted hard drive but get an error "Not a valid CoreStorage Logical Volume Group UUID"

    Ok so I encrypted an internal HDD with DOE compliant encryption, and forgot the password. I am not using a typical mac bootloader so apple C when its booting will not work to delete it before its mounted. I have to do it through the terminal. The drive I want to delete is HDD2. Here is the screen capture of running diskutil cs list in terminal.
    Then I disconnected everything to avoid problems, leaving my encrypted HDD only, copied the UUID, it's in this format:
    diskutil cs delete XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX
    But I am unsure which group or physical UUID I need to use, there are three associated with HDD2, logical volume group, physical volume and logical volume family. I thought before pressing enter I better ask first ... as I tried it on the physical volume first and I got the error in the title so dont want to start guessing what do to.
    Thanks                       

    Is it not good form for members to advise about using the console? Surely some members are knowledgeable enough to tell me the answer to this .... I know it's easy to bork your system up totally with the console but I'm desparate, my main drive has 1GB free!

  • How will the new OSX Mavericks affect applications already installed and using Mountain Lion?

    How will the new OSX Mavericks affect applications already installed and using Mountain Lion?

    If you're asking about compatibility, that would be something you would need to ask of the app developers, though most apps compatible with Mountain Lion should be compatible with Mavericks. You can also consult the tables here:
    http://roaringapps.com/apps
    though that information comes from user reports and so should not be considered authoritative.
    If you're asking whether installing Mavericks will delete your apps, no, it won't, though a good backup is always highly recommended.
