creating partition

[skmdu]

hi,

I have a linux machine with 64bit os installed.

[root]# uname -a
Linux sc-s1-172-16.a.com 2.6.18-128.el5virttest5 #1 SMP Thu Jan 22 12:14:52 EST 2009 x86_64 x86_64 x86_64 GNU/Linux

Is it possible to create new partition in this machine and format that partition alone to 32 bit. (that partition alone should be like 32 bit)..

Is it possible? If possible how to do this?

Please give your ideas..

Hi and Welcome !

What do you mean by "format partition alone to 32bit"? Patition or Filesystem has nothing to do with 32/64 bit.

Why do you want to create new partition?
Lets check partition structure of your harddisk. Post output of fdisk -l command here.

[skmdu]

scenario is like this:

A) assume that i have a machine with 32 bit OS installed.
and 4 partitions are available in that.
Now upgrading the machine to 64bit except one partition.
so now one partition is 32 bit all the remaining is 64bit.

I believe you got my above point..

B) Now I have the following.
one machine in 64bit os installed. ( whole 64bit).

I would wanted to make my machine i,e 64bit like A (first point).
(one 32bit partition and all remaining is 64bit).

Am trying to make that setup.

This is my requirement. Give your ideas that how can i make this setup?

Please ask if you are still not claer..

Hi devils casper,

You asked for fisk -l, am posting my output here.

[root]# fdisk -l

As Devils Casper said,I also believe partition has nothing to do with 32/64 bit machine.

Just create partition using usual procedure (fdisk) and then install both 32 and 64 bit OS.

I believe 32-64 only differs in CPU speed and memory addressing related to RAM ...I'm not heard anything about file system/partition..

check this link :

thanks for your valuable reply lakshmipathi.

I understand that, 32bit/64bit is not related to filesystem/partition.

Kindly clarify me one thing..

As i explained my scenario,

I have a 32bit machine. and upgrading this machine to 64bit except one partition.

Now will all 64bit applications can read the files from that partition which is not upgraded ? will it be a problem?

64-bit - Wikipedia, the free encyclopedia
Running 32-bit Applications on 64-bit Debian GNU/Linux

I checked few sites but response mostly seems to be yes...but it also depends the application you are running....if you provide more details about which machine (intel/amd) you are using ? Whats the main application you are running on system ? what's the distro?

someone can provide you more info.

hi,
let me give my whole requirement details over here.

as i posted my scenarios in prev post,

let me explain in very detail...

1. I have a machine which is 32bit, in mysql 3 is running.
all the DB files are there in one partition.

2. Now am upgrading this machine to 64 bit except that DB files partition. bcoze that partition is having very huge data.

3. After upgrading to 64bit, now mysql 5 will be available.
Is this mysql 5 can be able to read that DB files in a partition which is not upgraded to 32 bit? This is my doubt.

If you're upgrading the OS to 64-bit, all 32-bit apps should still run properly.

[skmdu]

yes 64bit mysql application will run.
But DB files are still 32bit.
64 bit mysql can read 32bit DB files and work?
