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

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!!

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.

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.

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.

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.

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

Unable to change to GUID partition scheme so Snow Leopard can be installed

Upgrading from OS 10.5.8 to Snow Leopard 10.6.3 on Macbook 4.1 with Intel Core 2 Duo, 2GB RAM. Instructions state "Macintosh HD" can't be used because it does not use the GUID partition Table Scheme. Use Disk Utility to change the partition scheme. Select the disk, use the Partition Tab, select the Volume Scheme, and then select Options.
Problem: The Options button is grayed out. The Partition Map Scheme is Apple Partition Map.
Note: Macbook purchased in 2008, but the hard drive was replaced in April 2011. Hard drive Information:

How do I change the partition scheme to GUID?

This requires that you repartition the entire drive as follows:
Drive Preparation
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. At this point you can quit DU and return to the installer and install Snow Leopard.
If you have data you wish to save then you need to backup before doing the above.

How do partition a hard drive with different partition schemes?

How can you partition an external HD with different partition schemes for different partitions? GUID one one partition and Apple Partition Map on another?
Thanks.

I am trying to add a second partition to my (1TB) external firewire HD. Apparently it was preformatted as "MS-DOS (FAT)" and I started putting lots of files on there. Now the "partition" option in disk utility shows me the one partition that's on there, but all options are grayed-out - I cannot add another partition, it seems, nor change anything on the existing one. Is there any possible solution other than totally erasing the disk and starting from scratch? I would be hard-pressed to find enough disk space to (even temporarily) store the stuff that's already on that HD.

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

TimeMachine Fails with PowerPC / GUID Partition Scheme / 10.5.2

Just a short question to clear something up:
I have an external drive, partitioned using the GUID partition scheme attached to my MacPro. Before the update to 10.5.2, I was also able to back up my PowerBook over the network to this disk.
After the update, I get the following console message:
2008-02-14 18:49:06 /System/Library/CoreServices/backupd[450] Error: Volume at path /Volumes/Satinav does not appear to be the correct backup volume for this computer.
2008-02-14 18:49:06 /System/Library/CoreServices/backupd[450] Backup failed with error: 18
[This article|http://docs.info.apple.com/article.html?artnum=306932] explains that Time Machine disks should be partitioned with the Apple Partition Map when used with PowerPC-based Macs. If that's so – why did the backup work before the update? Any explanations? Any solutions without having to re-partitioning the entire drive?

Repairing the Hard Drive and Permissions
Open Disk Utility in your Utilities folder. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now shutdown the computer for a couple of minutes and then restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger, and 4.1 for Leopard) and/or TechTool Pro (4.6.1 for Leopard) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

How to simply remove Partition Schemes or Partition Functions

Partition: Need help on Partition Scheme

I have question about partition scheme. The partition scheme has a starting partition
filegroup "Inv_200806" which is repeating twice. This scheme and function is already in use on the tables. I was wondering why does this partition
filegroup is repeating twice. Is it normal or recommended to do that?
Also, does this mean that Inv_200806 is a default/primary partition
filegroup after we do purging on the partitions and insert the data again in a table (which falls under purge boundary range)?
FYI: When I checked the boundary range of both Inv_200806 filegroup, first one has NULL boundary range and the second
has "2008-06-01T00:00:00.000'".
Any help /guidance would be appreciated.
Thanks!

I have question about partition scheme. The partition scheme has a starting partition filegroup "Inv_200806"which
is repeating twice. This scheme and function is already in use on the tables. I was wondering why does this partition filegroup is
repeating twice. Is it normal or recommended to do that?
Also, does this mean that Inv_200806 is a default/primary partition filegroup after
we do purging on the partitions and insert the data again in a table (which falls under purge boundary range)?
FYI: When I checked the boundary range of both Inv_200806 filegroup,
first one has NULL boundary range and the second has "2008-06-01T00:00:00.000'".
Any help /guidance would be appreciated.
Thanks!
