Q: Loner: "Your disk could not be partitioned" error. Please help

Hey, Loner

 

After recovering the disk space, I tried to run BCA. I used an 64bit Win10 .iso downloaded from Microsoft. BCA created the install disk, downloaded the support files, and allowed me to choose my partition size (even split) on my 3TB Fusion drive. Then I got the error.

 

I reset SMC

Rest PRAM

 

No external devices are plugged in.

 

I repaired the drive in disk utility, as well as rebooted in single user mode and performed a /sbin/fsck -fy repair.

 

Also, I booted into safe mode to try BCA from there, but it couldn't find the Win install disk even though disk utility could find it.

 

Here is my current diskutil list:

diskutil cs list

That is as far as my current research into the problem has brought me. I do remember seeing a bunch of odd disks added to diskutil when run in repair mode. There were about ten of them. I am not sure if they were repaired during the previous processes.

 

Ideas? Thanks!

A:

We built your CS volume/volume group by hand, so there are no individual disks as they are not part of the CS setup. In Internet Recovery, click on Utilities -> Disk Utility and select the outermost disk, and click erase. Once it is erased, try your TM Restore.

    As a test, can you use Disk Utility to create a FAT partition of 1TB or larger, and check the output of diskutil list disk1 and sudo fdisk /dev/disk1 and check if it works. If it does, you can always delete the partition and use BC Assistant.

    Thanks. I tried to add a 1TB Fat partition that failed. I went into recovery to look at diskutil list. I took of a photo of the screen because I have no idea how to screenshot from recovery.

    I am not sure how exactly to use sudo fdisk /dev/disk1. From recovery?

    There is a tedious mechanism in Recovery Console of 'switching' between applications like Safari and Terminal by quitting the current application (say Terminal) and start a different application (e.g. Safari). This can potentially avoid taking photographs.

     

    If the FAT partition creation failed, then there is no need for the fdisk command. "sudo" is needed under normal OS X boot up, but Recovery console does not need the "sudo" part since you have root privileges in Recovery console.

     

    Do you have a backup of your OS X partition via Time Machine (or another mechanism) on an external disk? If not, please create one, before we try to fix this issue.

    Can you post a text version of the diskutil cs list output, so I can cut-and-paste the values into commands?

    Recovery will give you identical information. This will work.

     

    1. Boot into Internet Recovery (not Local Recovery) using Command+Opt+R.

    2. Erase the Macintosh HD Logical Volume - diskutil cs deleteVolume 13D6F74D-5EC4-4E76-8B61-F6060A2BCDBE

    3. Erase the Macintosh HD Logical Volume group - diskutil cs delete 23B74634-AC44-45FC-9C0C-6667F41B0DF9

    4. Erase the the SSD part of the Fusion drive - diskutil eraseDisk jhfs+ SSD disk0

    5. Erase the HDD part of the Fusion drive - diskutil eraseDisk jhfs+ HDD disk1 (Please ensure disk1 is your HDD)

    6. Re-create the CS LVG - diskutil cs create OSX-Macintosh-LVG disk0s2 disk1s2 (please ensure the SSD disk is first, otherwise you will have bad performance).

    7. Re-create the CS LV - diskutil cs createVolume TheLongStringFromStep6 jhfs+ "Macintosh HD" 100%

    8. Restore OSX from TM Backup.

    9. Retry your Windows installation using BC Assistant.

    Hey, Loner.

     

    All has gone well. I am stuck on step 7.

     

    I enter:

     

    diskutil cs createVolume OSX-Macintosh-LVG Jhfs+ "Macintosh HD" 100%

     

    and it returns

     

    Error creating CoreStorage Logical Volume: Not a valid CoreStorage Logical Volume Group UUID (-69778)

     

    Thoughts? Thanks!

    You need TheLongStringFromStep6 as shown in step 7. Please post the output of diskutil cs list.

    Loner, you'll have to forgive me.

     

    Am I reading this correctly that I replace TheLongStringFromStep6 with a string in step 6, ie., something other than OSX-Macintosh-LVG? If so, please clarify because I am confused.

    1. diskutil cs delete E552F8B9-D1CF-4BC4-AD31-A3274A1F6D75

    2. diskutil cs create OSX-Macintosh-LVG disk1s2 disk0s2 (the order MUST have the 121GB disk first, otherwise the performance is really bad).

    3. Step 2 will generate a new long string (UUID) similar to E552F8B9-D1CF-4BC4-AD31-A3274A1F6D75. Copy this string.

    4. diskutil cs createVolume PasteTheStringFromStep3Here jhfs+ "Macintosh HD" 100%

    That step succeeded, but now I am getting an error when I try to restore. It tells me:

     

    An error occured while adding a recovery system to the destination disk.

    Restart your computer, and then try restoring again.

     

    Thanks!

    Can you run a SMC and NVRAM Reset and boot into Internet Recovery and then try to restore your TM backup? Please disconnect the USB once you have booted in Internet Recovery.

    Hey. I reset SMC and PRAM. But same error when trying to restore. You said to disconnect the USB during recovery. I did, but I had to plug it back in for my backup, which is a on an external hard rive.

     

    Thoughts?
