Re: Considerations before you install

Post by GuttaMan »

Now let me ask, If I already plan on creating a separate /usr, /opt, /var, and /home partition, how big (or small) does the root partition need to be? I'm thinking about re-installing Daryna for now, and I'm looking at my current partition and wondering since I got all these separate partitions, does the root really need to be 10 GBs?

Well, the truth is that most of the space used in / is in /user. /var is a work area, and unless you are compiling programs and putting them in /opt, then /opt is going to be empty. Some games may install in /opt, but none that I know of in the repos. My /opt has zero, nada, nothing in it. Ubuntu doesn't use /opt for any of its' default installs, to my knowledge.

If it was me, I wouldn't put but about 4 Gig. in /. No more than 5 Gig. That is over kill just to make sure /tmp doesn't ever overload anything.

I am using the KDE version, which is bigger than Gnome. I have lots of extra programs on mine for testing and play. As an example, I have three different office suites installed. My total install, including /home is only 7.5 Gig. Of course I use data partitions for my data. My /user is 5.3 Gig. That is where all your program files go. As you can see everything else including the /home config files is only a bit over 2 Gig.

In your case, since you want to split it up, I would probably go with 8 - 10 Gig. /user, 2 Gig. /var, 4 - 5 Gig. /, 8 - 10 Gig. /home, and your data partitions. If you think you will have a lot of special programs that you will put in /opt then make an /opt partition of whatever size you think is appropriate. As you can see that gives you lots of expansion room.

The bottom line is, you know your needs better than I do so size according to what you think is best. One thing you can do to conserve resources is to use the ext2 file system on the /user partition. /user is very seldom written to so a journaling file system on /user doesn't buy you much and costs you cpu cycles and drive space. Just remember. The larger your partitions are and the farther they are from the top of the partition table, the slower they will be. Also, there is no law that says you can't expand a partition later if you need more space. You don't have to commit all your space up front. You can always save some unallocated space to use later where ever you need it.

Have fun, :-)

Fred, I got myself a good learnin from that last post. I installed a nice bunch of different applications since I did the reinstall and the /opt partition didn't get touch one time, so I'll just leave that alone from now on. Other than that, I will utilize this thread again and that last post when I fool around with these partitions again. Preciate it man! 8)

Okay, I keep my partitioning very simple. 3 partitions:

sda1: documents/music/pictures/etc - 40-45 GB
sda2: os - 10-15 GB
sda3: Linux Swap 1-1.5 GB

All except sda3 is an ext3 partition. I keep it simple and easy to upgrade.

What an interesting thread!

Fred, you said in one of the posts that one could leave some space unallocated and then add it to another partition when the need arises... am i right?

how do we do this?

for explanation's sake... lets say we have a hardisk partitioned like so

sda1 - swap - 1GB
sda2 - / - 8GB
sda3 - / 20GB
sda4 - unallocated - 10GB

now if / is full and we need more space how can we add the unallocated space to / ? or only part of it...?

shane,

Using the latest stable version of Gparted, you have the option of shrinking, expanding, or moving a partition. In your case, let's say you want to add 2 Gig to your sda2 partition. You would move your sda3 partition down 2 gig. You would then expand your sda2 partition to use up the 2 Gig you just made available.

Hope that answers your question. The url below will take you to the site where you can download the latest stable version of the Gparted live cd iso.

oh like that... i thought there was some way to create a 2GB partition after /home and have that and sda2 be recognized as one... i think there is a way to do that if i'm not mistaken... like how they have RAID stacks... if thats what they call them...

but coming back to gparted... i have tried editing partitions from ubuntu live cds but i wasnt able to change the starting point/sector of a partition... only the end. maybe i was just doing something wrong...

i didn't know about the beginning of the hard disk being faster... i would have thought the end would would be faster... i.e. at the edge of the spinning platter so the speed is faster than towards the middle... and about swap on multiple hard drives... thats what i used to do till some guys on linuxquestions.org told me it wouldn't improve performance... but logically thinking it should, right?... btw i used to do that in windows too with pagefiles... oh the bad old days of tweaking Windows :lol:

No, you have been misinformed. You can expand the partition size but you can't run 2 partitions mounted to the same mount point.
but coming back to gparted... i have tried editing partitions from ubuntu live cds but i wasnt able to change the starting point/sector of a partition... only the end. maybe i was just doing something wrong...
Please reread my post. You need a later version of Gparted than used in the install cd. Use the latest stable version, as I indicated.

You are both right and wrong here. The outside of the disk is the beginning of the partition table, and the left side of the Gparted graphic. The outside of the disk or the first partition on the disk is faster than one located close to the inside of the disk or at the bottom of the partition table.

The speed difference used to be much greater than it is with modern drives however. Drives used to have a single, large diameter platter. Now they are made with several smaller diameter platters, which reduces the speed difference from outside to inside of the platter.

And yes, you can use 2 swap partitions. It only improves performance if they are located on different drives. If you need 2 Gig of swap, two 1 Gig swap partitions located on different drives will be much much faster than a single swap partition. Linux can strip across drives on swap partitions. It is similar to a two disk RAID 0 set-up.

Fred,
How do I mount my NTFS partition, or any other data partitions in the Home folder. Is there a tutorial somewhere explains this?

big_dog1968,

I don't know that there is a real how-to, but I have explained it a number of times in various posts. To keep you from having to look it up, here is the short version. :-)

Create a folder in your /home directory. As an example, we will call it "NTFS_Data". (no spaces in the folder name)

Open /etc/fstab for editing and put this stanza, corrected for your system of course, in it anywhere, save and close.

That's it. When you reboot you will be able to open the folder in your home and see the contents of that partition.

# /dev/sda1
/dev/sda1 /home/Nice_Dog/NTFS_Data ntfs defaults,umask=007,gid=46 0 2

Hope that helps you.

Thanks Fred,
I got it to work, but now I have an icon for the drive on my desktop.

Is there a way to do what I just did without having the icon for the mounted drive on my desktop? I plan on doing several partitions as you suggested (video, mp3, pics...etc), and don't want to see them all on the desktop if that is possible.

I may try to look it up at some point anyway, because although the quick help was greatly appreciated, I also want to learn more about linux. I have dreams of someday being a Fred-like guru myself! :D

Thanks again.

Apparently, It placed a link on the desktop. You should be able to just put it in the trash.

Fred,
I ran into a hick up when I tried to add more partitions. It defaults to Primary and I didn't realize there was a limit to the number of primaries and then I couldn't figure out how to fix it so I wound up deleting all but XP's partition and starting from scratch this time being careful to select Extended and then adding Logical partitions. It works great now. I even added a couple of extra partitions in case I want to try other flavors of mint or distros without formating my Mint Partition. I took the suggestion and made the data folders NTFS, so now they are shared with XP. Beautiful.

From now on I will think of you as Obee-Fred-Kinobe, because you are the jedi master of partitioning! :lol:

Hello All readers of this thread.
I'm really welcome fred's suggestions as they compare with my experience in many installations -- mostly.
The best way for Gamers might be an extra partition /usr/local for installation.
I really surprised that this Partition is not mentioned by anyone else.
Most, if not all Games which comes with installers -- as they are commercial or free -- recognize if they do have write permission to
/usr/local In Ubuntu and Linuxmint, the normal User does not have write permission to it.
So I am changing this with a simple sudo chmod -R bed:bed /usr/local/. (bed is my login name)
This is not recommend for a multiuser system but for a Desktop PC I think this security downgrade is bearable.
Now, the games will be installed in /usr/local/games and make a link to /usr/local/bin/gamename.
So what is the plus for my approach?

Code: Select all

 /          --> 12 G
/usr/local --> 90 G
/home      --> 90 G
  • This meet fred's suggestions to use more smaller partitions.
  • A new Linux Installation does not imply new Installation of Games in /usr/local (ever installed UT2004 twice?)
  • Now in /home there is private stuff only, no Games
Just my two cents

Wh1sper,

Greetings Sir,

Your suggestion is a reasonable one for a serious gamer. Actually, the recommendations here are for basic first or second time GP installs and do not take into consideration the many special needs of some users, gamers being one of them. :-)

I would only make one suggestion in your case. Go one step further and change the permissions for the /games folder only, instead of the whole /user/local folder.

Wow! 90 Gig of games! You must really be into games. :-)

Enjoy life,

Fred

Fred,
How can I label the partitions for easy reference? In XP you had a volume label. These are NTFS drives created in gparted. There may be something simple I am missing, but so far I have not figured out how.

big_dog1968,

There are a couple different ways, but it would probably be the easiest to do it with the latest stable version of Gparted live cd, which can be found at the link below. It is a good idea to have a Gparted live cd around anyway so it won't really be wasting a cd for this one task.

http://sourceforge.net/project/showfile ... _id=271779

There is an option available to label the partition without doing anything else to it. It will change the UUID if you are still using UUIDs however.
