Made a mess of my partition scheme

I had just received my new late 2012 iMac, and transferred over all the information from my old iMac to the new one via Setup Assistant.
I went into Disk Utility to take a look at my Time Machine backup and noticed what seems to be a huge mess in the man hard drive.

I stupidly then attempted to erase the disk2s1 and the disk1s1 partitions, and then allocate that space back into the Macintosh HD, which didn't work (and now they are just empty volumes).
This is what I get in Terminal running the diskutil list command:

That being said, Find My iMac is now greyed out, and the Recovery HD (while bootable) doesn't seem to be recognized properly for iCloud and Filevault settings, etc.
Thank you very much for your help!
P.S. I also get "This disk doesn’t contain an EFI system partition. If you want to start up your computer with this disk or include it in a RAID set, back up your data and partition this disk." when trying to repair disk.
This applies to both “APPLE HDD ST3000DM001 Media” as well as “APPLE SSD SM128E Media”.

You Broke the Fusion drive, which is what I stated in an earlier post. There is only one thing to do and that is to completely break up the Fusion driver into two completely separate drives, SSD and Mechanical Hard drive, then try to Re-Create it.
If you do a Google search there are articles on breaking up fusion and re-creating it. You will need to follow one of those to get it back. Or use it as two independent drives/partitions.
Then Do NOT try to Partition it again. A Fusion Drive is a Combination of two physical drives and Can NOT be partitioned any other way then One Large, Combined, Drive/volume.
Or you can leave them as 2 separate drives/volumes and then you can partition either any way you want.

I can't install OS X Mountain Lion due to wrong partition scheme.

I just bought and downloaded Mountain Lion on my Mac. Now I'm trying to upgrade but seems to fail.
I made a second partition on the same drive last year to put in Gentoo (unix) on one and by so used a double boot. When i released Gentoo from the harddrive i could no longer make it one partition.
Now it says that I don't have the right partition Scheme and tells me how to change it. Only problem is that I can't change the partitions. At all.
What should I do? Clean install? How?

In Disk Utility, where you were, in the left hand column in the window highlight the Hard Drive that the Partitions are on>in the upper right portion of the window click on the betton "Partition">below that a diagram showing your hard drive with its various partitions will appear> click on one of the Partitions shown that you want to Remove, to highlight it, and click on the "Minus" symbol at the bottom of the column>this action will Remove That partition only. Repeat these steps for each Partition that you want Removed. Do NOT remove the Partition that your Main OS is on that you want to keep. And Removing each of those Partitions will of course DELETE ALL THE DATA contained on each one. Make backups before you start of anything you want to keep off of them.
Hope this helps

Choosing an External drive partition scheme

I have a 1 TB LaCie drive that I am currently using with a MBR partition scheme. It has two partitions: one for time machine and one for windows.
What I want is to use this drive to hold my time machine back ups in one partition for Lion, which I am about to switch to and install on the iMac internal drive, my windows stuff in one partition, and a third partition in which I would put a clone (CCC) of my current internal drive (Snow Leopard) that I could boot from when desired. This would enable me to run Lion normally from the iMac's internal drive, switch to the windows partition (holding down the option key when powering on) on occasion when I want to work in a windows only app, and using the same option key on power on trick, boot into Snow Leopard when I need to use old, apps that won't run on Lion.
For this, I assume that I should use the GUID partition scheme. Am I right? Is there a better way to accomplish my goal?

Just a cautionary word about putting all your backups on the same drive: hard drives fail - they all do; some sooner than others....... I have several partitions on mine; however, I have three external drives, so everything is backed up x 3 (redundancy is good for backups).
Having said that, I don't run Windows, so I can't help with that part; for an external to be bootable with a Mac, yes, you need GUID partition scheme. It's also a great idea to put a bootable clone of your Snow Leopard install on one just in case - that is the easiest way to revert if a major problem arises. I've heard there are some external drives which cannot boot a Mac, so make sure yours is. And, you may want to have another partition for your new (not yet installed) Lion install...... so I think I just made you run out of available space on your external

Partition Scheme

Hello everyone,
I would like to install Arch and want to confirm that the following partition scheme looks appropriate for a regular desktop environment. Please feel free to suggest any changes.
I have 118 GB to spare:
/ 30 GB [ext 4]
/boot 100 MB [ext 2]
/var 12 GB [reiserfs]
/home 76 GB [ext 4]
I don't plan to include a swap since I have 6 GB of RAM and don't use hibernate on my laptop, only suspend.
Is there any good reason why I would need to make a separate /usr or /tmp - would the security/stability/speed advantages be significant? I would like to keep the partition setup as simple as possible.
Thank you in advance.

I would like to caution you about one thing.
I have /var on it's own LVM Logical Volume. After the change that made systemd's journald start to keep the journal in /var/log/journald Systemd was unable to unmount /var at powerdown, because journald was still writing log's to it. I simply changed it back to writing the journal to /run
Personaly, I think the wiki just says that reiserfs is a good choice for /var simply to make people understand that there is more then just the ext filesystem. However, I looked into reiserfs, JFS, and XFS... to me they all seemed to have some deeply rooted problems that could lead to corruption and/or fragmentation. I simply use ext4 everywhere, aside from the recent ext4 problem, ext4 is basicaly rock solid and has good performance. EXT4 is lightyears ahead of NTFS or HFS+ that's for sure
Also, if you have 6GB of RAM. I highly suggest mounting /tmp as a tmpfs in RAM. Then configuring FireFox to keep it's cache is /tmp
/etc/fstab
tmpfs /tmp tmpfs nodev,nosuid,noatime,size=4G 0 0

3 partition scheme using Lion and Winclone

Hi All,
I used this tutorial to set up a 3 partition scheme to my iMac (OSX Lion):
http://forum.parallels.com/showthread.php?t=88729
I have done everything like the tutorial instructed, but W7 won't boot anymore. I even can't select Windows anymore while booting. The tutorial also describes this, so it is not something weird.
I followed every step of the tutorial, so i made the W7 (Bootcamp) Image. But when i want to restore this image, winclone gives an error. This is what the log file tells me:

Does someone know what to do?
Regards! Guido

I don't do Windoze, but Lion does not like "non-standard" Boot Camp installations, and as I understand it, that means a single OSX partition and the Boot Camp partition as set up by Boot Camp, with no changes to either partition since. Period.

Installing ox s 10.6 but getting error message to change partition scheme to GUID?

Please help, I currently have OS X 10.5.8 and bought OS X Snow Leopard however after inserting the disk I keep getting an error message saying I cannot use Macintosh HD to install Snow Leopard because it does not use the GUID partition table scheme? How do I do this becuase every time I go into my disk utilities i am unable to change the partition scheme? Thanks!!

so I tried what you said however it gives me a message that says "this is the startup volume, it can not be erased" any recommendations?
Use the disk utilities from the 10.6 installer disk.

Note that this will completely erase the disk.
You need to boot from the DVD, not the internal drive

Physical model attribute "Partition Scheme" not saved. (SS2000)

Hello,
I believe this is a bug report.
Scenario:
I have a physical model of a SQL Server database. The model contains partitioned tables, 1 partitioning function and 1 partitioning scheme. If I open the physical model properties of an index or a table, set the "Partition Scheme" attribute, save, close and re-open the model, the "Partition Scheme" attribute is lost. If I don't close out and just re-open the properties page, the attribute is retained. Some how, the attribute is lost in the persistence layer.
If there is a reason the attribute is being reset, please let me know.
Thank for your help, and all the great products you guys make,

Hi Kurt,
If there is a reason the attribute is being resetUnfortunately there is a bug causing the problem. Fix will be available in next patch release.

Shadow tables that have been created via the new partitioning schema

Hi,
     Complete Partitioning :
                In a complete partitioning, the fact table of the infocube are fully converted using shadow
tables that have been created via the new partitioning schema.
               in the above Explanation what is the meaning of shadow tables which perform the
               partitioning of an info cube.

Hi
Shadow tables have the namespace /BIC/4F<Name of InfoCube> or /BIC/4E<Name of InfoCube>.
Complete Partitioning
Complete Partitioning fully converts the fact tables of the InfoCube. The system creates shadow tables with the new partitioning schema and copies all of the data from the original tables into the shadow tables. As soon as the data is copied, the system creates indexes and the original table replaces the shadow table. After the system has successfully completed the partitioning request, both fact tables exist in the original state (shadow table), as well as in the modified state with the new partitioning schema (original table). You can manually delete the shadow tables after repartitioning has been successfully completed to free up the memory. Shadow tables have the namespace /BIC/4F<Name of InfoCube> or /BIC/4E<Name of InfoCube>.
You can only use complete repartitioning for InfoCubes. A heterogeneous state is possible. For example, it is possible to have a partitioned InfoCube with non partitioned aggregates. This does not have an adverse effect on functionality. You can automatically modify all of the active aggregates by reactivating them.
Hope it helps and clear

GUID Partition Scheme - Need clean install: can I restore files from TM?

So, here's my problem. I have an Intel PowerMac (first series after the G5) and when I try to install SL I get the following error message: "Can't Install Snow Leopard Since Disk Does Not Use GUID Partition Scheme". I guess it's something related to the fact thet I previously upgraded from an old iMac with a PPC processor (Apple partition vs. GUID partition).
Anyway, accoding to my understanding, the only solution for me is to do a clean install by wiping the HD and re-partitioning it.
Now, my question is: can I use my current TM backup to later restore apps/prefs onto the new SL system? I believe that TM now has an Apple partition scheme that reflects the one I have on Leopard 10.5. Is that right? Will I encounter any problem because of the different partition type of TM?

"Anyway, accoding to my understanding, the only solution for me is to do a clean install by wiping the HD and re-partitioning it."
Right, except that your drive will automatically be erased when you set up the GUID partitiion.
"Now, my question is: can I use my current TM backup to later restore apps/prefs onto the new SL system? I believe that TM now has an Apple partition scheme that reflects the one I have on Leopard 10.5. Is that right? Will I encounter any problem because of the different partition type of TM?"
Your TM backup should work. But, there are not many guarantees in life. You could tranfer you TM backup temporarily to your internal and then make a bootable clone of your internal on your external. Afterwards, you could transfer the TM backup back. Then, you'd have two sources from which you could restore items.

Made a mess with Migration Assistant, Two user accounts. Help!

I got a new MacBook Pro Retina with Yosemite. Tried to use migration assistant to take files from my old 2008 MacBook (I only wanted photos, videos, music and documents - no applications, etc). After an excrutiatingly long time, I've made a mess of my new MacBook Pro. I now have two user accounts with my name. How do I delete the second? I have tried going into system preferences > users and push the delete key. This DOES NOT work! It makes that ping noise. I am computer slow so please help me with step by step directions on how to delete the extra user.
Also, I have now realized that this awful new MacBook Pro Retina has no disc drive and I have a 2008 Microsoft word CD I want to install. What can I do here?
For the record, I'm hating this new computer.
Thank you guys!

1. Log out of the account you want to delete, unlock the Users & Groups pane, select it, and then delete it.
2. Use an external optical drive such as Apple's USB SuperDrive, or one inside another computer.

Exporting/Importing partition schema

Hi,
We are trying to manage multiple repositories for a project and in
particular we use a devopment/test rep and a production rep ( containing a
production plans snapshot ).
When a plan is moved from a development repository to the production one,
the partitioning previously done is lost. In this case developers have to
partition from scratch.
Moreover in our repository management policy ( apart clean up ) , we
destroy periodically development repository and import saved plans in a new
created one. This procedure causes the same problem described before.
Is there any chance to export the partition schema done in development
repository in order to re-apply the partitioning to the same plan in new
one, using fscript ?
Is there any other way to do it ( maybe via repository hooks and a tool
application ) ?
Thanx
Fab

Fabrizio,
We have a tool that will do this, and a number of other things for you. It
not only saves partitioning information, but it also:
* Reads your application defintion, along with the partitioning information
from the repository,
* Creates deployment and installation scripts,
* Analyzes your application for over 20 different performance and
scalability problems,
* Captures the supplier plan relationships for each partition as well as
for the entire application,
* Graphically shows partitioning structure, similar to partition workshop,
along with all partition and service object properties,
* Has Web and IIOP property sheets which are read from the application,
* Saves operational information, such as outage schedules and external
interfaces,
* Records special runtime properties of classes in your system
We offer this as part of our "Designing for Deployment" workshop. You can
send me a separate message for information about the workshop and the tool.

Closed captions + SDH made a mess by Apple TV 6.0. Any fixes?

We've found that the Apple TV 6.0 software update made a mess of closed captions + SDH . It suddenly changed the size and color and font on its own. To make things worse, when we try to send them right with the new customizable closed caption style settings, we can't make them look like they did before the 6.0 software update. The customizable choices are too small, too large, or much too large than they were before.

The movies are not orphaned. There is a flaw in the latest version. There are several posts on this issue. Actually be happy they are on AppleTV. Several of us have purchased through iTunes. We sync, but when the computer loses the link with ATV requiring a new code. When the code is entered it re-syncs itunes and ATV, but you lose the movies that were transferred to ATV requiring you to move movies back to ATV.
They are probably working on a fix.

Can't format SSD to GUID Partition Scheme

I can't format my SSD to GUID Partition Scheme with Mac OS Extended(Journaled) but Master Boot works fine. When i try, it stucks even i tried Recovery HD. You can see issue in picture. What should i do?
MBP Mid 2012 OS X Yosemite 10.10.2
SSD is Samsung SSD 840 EVO

c_arslan wrote:
Toshiba is the current boot drive. I can't use the SSD because of the format of it. So there is SSD inside without format, filesystem etc.
In that case, since the SSD likely came with an MBR Partition Map, at the beginning of your format process, did you choose the Partition button, pull down the drop-down menu under Partition Layout, and choose 1 Partition, and then, using the Options button at the bottom, select GUID?

Questions concerning new partitioning scheme

Hi
Since I'll be upgrading my home and office workstations soon, I've decided to tinker a little with my current "go-to" partition scheme to better serve my current project needs.
Let's start with the office workstation. Here's the current scheme:
[256GB SSD]
sda1 # Windows boot
sda2 128GB # Windows system
sda3 ext2 500MB /boot
sda4 # encrypted
vault
vg # LVM
lv_root ext4 28GB /
lv_swap swap 8GB swap
lv_opt ext4 6-8GB /opt
lv_var etx4 24GB /var
lv_tmp ext2 2GB /tmp
lv_home ext4 [free-10GB] /home
free
And here is my current concept:
[256GB SSD]
sda1 # Windows boot
sda2 128GB # Windows system
sda3 ext2 250-500MB /boot
sda4 # encrypted
vault
vg # LVM
lv_root ext4 26-30GB /
lv_swap swap 4-8GB swap
lv_var etx4 12-16GB /var
lv_varlib etx4? 24-36GB /var/lib
lv_vartmp etx4/reiserfs? 2-4GB /var/tmp
lv_tmp ext2? 2GB /tmp
lv_home ext4 [free-10GB] /home
free
Basically the whole concept behind the change is to maximize /var flexibility/performance with applications like VMs (KVM) and containers (Docker). Was thinking about substituting LVM model with btrfs subvolume model, but I'm not convinced with it's maturity for production (will be a good choice for home workstation do).
Questions
1. Is separating /var/lib a good idea in those terms?
2. If so, what fs would fit in?
3. Should I consider creating separate partitions for other locations?
4. Any other tweaks/ideas that might come in hand?
5. (bonus) Which filesystems would You recommend for better compilation performance (ReiserFS/Reiser4/tmpfs)?

2 grubs because I was reading the wiki quickly and probably misread the section on bootloaders.
2 arch installs because I want one as my "stable" and one as my "unstable" installation. I'm taking this laptop with me overseas for work for a bit over a year and it will be replacing my desktop. I love to tweak my machine but I need to make sure I can do so without risking loss of everything. The idea is I can play with things in my "unstable" install and move them to "stable" if I like them. Honestly, the distro on that partition will likely change occasionally just so I can play around a bit.
I know I could just use a virtual machine but that's not how I want to do it right now.
