Partitioning two HD's

Postby Salorian on Fri Apr 03, 2009 9:50 am

Hello Everyone!

Tired of Windows, Ubuntu feels too bloated with crap, Mint sounds like a good in between!

I have 2 250gb HD's and am wondering what the most effecient\safest way to install Mint would be...

I'd like to have a very easy way to back up all of my data, should I need to upgrade\re-install at some point.

I'm thinking of the following...

HD 1:

/boot = 6gb ext3
/root = 12gb ext3
/swap = 8gb, I have 8gb of ram

HD 2 = backup, with random data partitions formatted to ext3. Going to leave about 80gb unallocated should I want to re-install Vista for some unknown reason.

My real question is, will I see any benefit in dividing up the /boot, /root, /swap partitions amongst both partitions? Or, is it better just to leave them all on the same drive?

I'm still a little funky on how the whole /home thing works, I assume that functions as my Program Files folder on Windows correct? Ideally, I'd just like a safe, yet effecient way to partition my drives in the event of a failure. (Just recovered my Raid 0 crapping out)

you'll want to leave them all on the same drive, you probably don't need more than a couple of hundred MB swap. /home contains any and all user-level customisations (any you wouldn't need to type your password to change) as well as all your data, see also: viewtopic.php?f=46&t=23980&start=0&st=0&sk=t&sd=a&hilit=partitioning

I would say:
HD1
/root = 10gb
/swap = 4gb
/home = the rest of the 250gb disk

HD2
/home/backup = 170gb *
/home/vista = 80gb *

* : these are mount points that you setup during the install.

To be honest, depending on what you're going to be doing with your OS, a 10gb / partition may be ok. But if you will be adding a lot of stuff to expand your OS, you may want something a little higher than that. I have my / partition set at 20gb, which leave a lot of room for my OS to grow should I desire to.

An 8gb swap is actually very high, considering you have 8gb of ram installed in your system. Mine is set at 256mb, and I have 4gb of ram installed in my system. Runs fine.

But you definitely want to have a separate /home partition should anything happen to your / partition and you won't lose anything.

atlef did a good layout for you to go by, but remember the majority of partition setups are personal preference, minus the swap and / partitions. You don't want too much, but you also don't want too little.

This is how I have my hard drive partitioned to give you something to go by, but this is not a be all end all solution for you, mileage and use may vary:

I have a 320gb drive in my laptop by the way.

Swap = 256MB (I have 4GB of RAM installed in my system)

/Boot = 256MB - formatted to ext2

Everything else is formatted to ext3

/ (root) = 20GB which should give me more than enough space for my OS to grow

/home = 25GB

/home/Pictures = 25GB

/home/Documents = 25GB

/home/Downloads = 25GB

/home/Music = 150GB ( I have a lot of music!)

/home/Videos = 25GB

Then whatever I have left over, I can put to use at a later time.

I copied this from another thread I posted in, so it looks exactly as I wrote it there.

Hope this helps you on your quest for the perfect partitioning scheme.

I don't compile a lot, and when I do it is cookie-cutter so I don't save the logs. I've yet to fill a 10gb partition, except for a brief period when Ubuntu Hardy was doing freaky things.

I had Intrepid installed with kubuntu-desktop and xfce-desktop on top, same partition, plus a dumptruck load of other stuff. Came close to 8gb. My typical installs are <4gb base, and well under 6gb fully loaded. So a 10-12gb partition for /boot / /home is, in my book, ample. Of course, this is with a seperate data partition and typically with symlinks of all the major directories in /home.

An 8gb swap is actually very high, considering you have 8gb of ram installed in your system.


Ridiculously high. An 8gb swap would be needed if you wanted to do hibernate and all 8gb of ram was full. But hibernate would be glacially slow to enter and leave because the entire state of the 8gb ram would need to be frozen and cached to swap and then thawed later.

Seriously, 8gb ram? If you're even touching the swap you're probably doing it wrong.

But you definitely want to have a separate /home partition should anything happen to your / partition and you won't lose anything.


I'm happy without a seperate /home simply because I don't store anything in /home except for .config and .pref files/folders.

So then I can say that my /home partition would be rather large, but then again I use a lot of brushes for GIMP and on the occasion I run Photoshop and other Windows apps in Wine. I tend to have a ton of brushes and other presets for Photoshop there too.

But to each his own I say. No one is going to get a "perfect" answer when it comes to partitioning, and I am far from being a Linux guru in any sense.

Absolutely! What I do works for me, but may not work for you. And versa-vica.
