format windows hd's to linux format - anyweb - 2006-03-28


i had a windows 2003 server which i have recently converted to Fedora Core release 4

 

the install basically used the first hdd (as i told it to) and the remaining three hd's still had the original 'dynamic disc NTFS' format on them from Windows 2003 server.

 

I wanted to format all the other three hd's to Ext3 filesystem (for journalling) and to do so i had to first change the partition info from the SFS filesystem to LINUX

 

here's the output before i did anything

 

Quote:[root@localhost ~]# fdisk -l

so above, as you can see,. /dev/hda1 is already in linux format (actually it's a LVM logical volume manager format which Fedora Core defaults to) and i want to change the other three hd's from SFS (dynamic disks in windows 2003 server) to Ext3 linux.

 

first off, i need to re-partition the hard disc's one by one, so i started with /dev/hdb

 

login as root and do this

 



Code:
fdisk /dev/hdb




 

you will now be given some info like this

 

Quote:The number of cylinders for this disk is set to 14593.There is nothing wrong with that, but this is larger than 1024,

and could in certain setups cause problems with:

1) software that runs at boot time (e.g., old versions of LILO)

2) booting and partitioning software from other OSs

(e.g., DOS FDISK, OS/2 FDISK)

 

Command (m for help):
now type the letter 't' as follows:- 



Code:
Command (m for help): t
Selected partition 1
Hex code (type L to list codes):




 

and now tell it what filesystem you want (83=linux)

 



Code:
Hex code (type L to list codes): 83
Changed system type of partition 1 to 83 (Linux)




 

finally you need to write those changes so do that with a simple 'w'

 



Code:
Command (m for help): w
The partition table has been altered!




 

 

to verify that the changes are made as root do

 



Code:
fdisk -l




 

as you see below, /dev/hdb is now type 83=linux

ok, now that's all done, you need to format the hdd to your chosen filesystem, i chose ext3 and this is how i did it

 



Code:
mkfs.ext3 /dev/hdb1




 

it won't take long, and once done you'll see something like this scroll by,,

and that's it, only two more hdd's to go ! 

thanks to znx and omegaevil for assistance with this, and below please see the 5 line version of this howto ;-)
