Hi !
I have a red hat 8.0 & Windows 2000 on a intel box with a 60 GB hard drive .
Only 20 GB has been partitioned into 10 GB of NTFS and 9 GB of Linux , file id 83 ext 3 and 1 GB of Linux swap , file id 82 .
I want to use some free unallocated space from the remaining 40 GB for my linux .
But I could not get fdisk (from the command prompt ) to show me the unallocated space and partition it .
I could see the unallocated free space when I run KDE hardware browser .
I could find the GUI disk druid too .
So How do I partition the unused free space for my red hat 8.0 .
Which utility do I use ?
When ever I use fdisk , and choose option n ( to add a partition ) , it gives an error message saying that I need extended partition or I need to delete old partition to create a new one .
But I have 40 GB of un used space on my hard drive.
Please advice .
Thank you for your help in advance .
cheers, bj
You have a bit of a problem. You'll need to create an extended partition to handle anything beyond the 4 basic partions. Let's make an example:
# fdisk /dev/hda
...blah...
Command (m for help): p
If it shows something like:
Disk /dev/hda: ..blah..
Device Boot Start End Blocks Id System /dev/hda1 1 20480 something 86 NTFS /dev/hda2 20481 40960 something 83 Linux /dev/hda3 40961 41960 something 82 Linux swap
Then you're okay.
Do:
Command (m for help): n Command action e extended p primary partition (1-4) e Partition number (1-4): 4
and that'll create the extended partitions you need.
Then, you can have up to 16 partitions iirc.
If you have all 4 primary partitions full, you have to do a few more steps.
boot into single-user mode (init 1)
# swapoff -a # fdisk /dev/hda
Then, you remove your swap partition, make the extended partition in the hole you made in the partition table, create the swap partition in /dev/hda5 in the same place on the hard drive you had it before. Make whatever other partitions you want in /dev/hda6, etc.
After you are done, do:
# mkswap /dev/hda5 # vi /etc/fstab
and modify the entry for the swap partition from /dev/hda3 (or wherever) to /dev/hda5, and reboot.
To make your life easier, you might want to look at LVM - http://www.tldp.org/HOWTO/LVM-HOWTO/. Came to Linux from AIX.
It's made chaining hard drives and dealing with expanding directories much easier. Windows has similar functionality in Server 2003 and (I think) XP Pro - just haven't played with it enough to be sure.
Good luck, Jim
