Erase "Logical Partition Group" Partition

Hi guys,
I have a 3 TB drive of which I've partitioned into (3) 1 TB volumes. 2 of them read Mac OS Extended Journaled and 1 reads Logical Partition. Is it possible to erase the Logical Partitioned volume, have it read Mac OS Extended Journaled, while keeping the other 2 in intact, with all it's info? For some reason, this happened when I was Carbon Copy Cloning the Marverick drive to 1 of these volumes.
Thanks,
CL

Yes - Disk Utility - select the partition and erase it with the Mac OS Extended Journaled. Hit the Option button and select GUID.

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? Any help is appreciated. I will post some screenshots with the details. Furthermore, here are some terminal commands I ran: /dev/disk0

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.

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

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.

Can I erase the boot camp partition and dual boot snow leopard and mountain lion instead

Please don't double post. Look at your other thread.
If you want to get rid of Windows and the BC partition use the Boot Camp assistant program to remove the Win/BC partition. Don't do it manually with Disk Utility Use the BC A program.

Logical Vs physical partitions ?

Hello BW Experts,
What is the diff between the logical and physical partitions. The partitions that we do on a cube based on 0calmonth / 0fiscyear is that logical or physical.
Suggestions appreciated.
Thanks,
Kalyan

hi,
in bw, physical partitioning done on database level and logical partitioning done with multiprovider. cube partitioning with 0calmonth is physical partitioning.
take a look

Database (or Physical) Partitioning
-Database tables are cut into smaller chunks (partitions)
-One logical database table
-Transparent for user
-Available for the following database management systems
Range Partitioning: ORACLE, Informix, IBM DB2/390
Hash Partitioning: IBM DB2/UDB

*Benefits
-Parallel accesses to partitions
-Read smaller sets of data Fast
-Deletion of partitions (DROP PARTITION instead DELETE FROM WHERE)
*Automatically Partitioned Database Tables (for Range Partitioning)
-InfoCube F-Fact table: partitioned by request
-PSA table: partitioned by request ODS
-Change Log: similar to PSA table
*User Defined Partitioning Criteria (for Range Partitioning)
-InfoCube E-Fact table
-Partition Criteria:
Time characteristics like month or fiscal period
-Note: Both fact tables are extended by the SID of the chosen time characteristic

NGRP_ODS_GBT redistributed on partition groups getting RSERRORHEAD error.

I am trying to distribute the NGRP_ODS_GBT partition group across 3 new partitions that were creted. I am getting the following error/failure on the redistribute CLP job.

Any idea what the issue may be?
System is a NW07 EhhPack 1/SP3 BI system on DB2 9.5

The partitioning key is used to determine on which data partition a particular row is located. Use
ALTER TABLE .... ADD DISTRIBUTE BY HASH ()
to add a partitioning key. The columns must be part of all unique indices defined for the table.
See the online documentation on ALTER TABLE for further reference.

Hi Donald,
RSERRORHEAD
If a record in PSA has a green status then no info is recorded anywhere.
In case of yellow or red status the info is written into RSERRORHEAD table. If a field 'ERROR' has 'X" then this record will be marked in PSA with the red status. If a record has been changed and before SAVE had a yellow status then 'X' will be in the 'CHANGED' field. There is also 'DELETED' field. And 'REQUEST' field is a name of the request related to this PSA load. It's the same name as you see to the right from a PSA icon in PSA area of RSA1.
There is also a RSERRORLOG table which contains parameters for error messages.
Revert for further info..
Cheers,
Tanish

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/

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.

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

Hi there,
Thanks very much for helping out with this, much appreciated.

Hi again OGELTHORPE.
I've already run two hardware tests. One quick one and one extended one. It was unable to pick anything up.
It's like everything is running perfectly, but when I go to erase the HDD or partition it, it pops up with the error message. Even when I try to erase and partition using "Terminal", I received the same error message.
It's beginning to do my head in, but will see if replacing the SATA cable will make any difference. If it doesn't, I'll hazard a guess it could be the Logic Board.
Thanks again for your suggestions!

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.
SO i cannot install system now. There's no visible disk any more.
