 |
|
| Hi, just tried yesterday to install Gentoo on my System. I created 3 partitons with fdisk and everything worked just fine. The only stupid thing was that the partions are all have the name /dev/hadp1, /dev/hdap2 and so on. The Problem now is, in my /dev dir is only /dev/hda so therefore i am not able to format any of these partitions. Is for sure a stupid questuion but so far i was not able to find out where my Problem is. Would be great if someone can give me a hind. |

I think maybe something has been confused somewhere, or something important was left out-- or maybe both have happened.
First of all where did you get the name hdap1 hdap2 etc?
Second did you remember to write your changes to disk before exiting fdisk? (I think the command is 'w' but I am unable to check right now.)
Once you have written the changes to the disk and exited I think you should then be able to see the partitions in your /dev. The partitions should be named /dev/hda1 /dev/hda2 etc. Once you have done all that you just need to choose your file system of choice and initialize the partition with the said filesystem.
Hope that helps!!

Question on top of question...
What do you mean by format? I was under the impression that, in order to partition, you had to format, and that, using fdisk, fdisk took care of formatting for you. (format example: a Windows partition is formatted as FAT16, FAT32, NTSF, etc. formatting simply establishes the type of filesystem of the partition.)

Did fdisk tell you that you may need to reboot in order for the partition table changes to take effect? Did these same problems persist across a reboot? Can you use | Code: | | # fdisk -l /dev/hda |
to tell whether or not the changes you made actually were committed?

Just like in an old Win9x setup you needed to create a partition table first with fdisk, then you had to put a file system onto those partitions. The same holds true with linux, fdisk does not format the partition--it simply writes the partition table to the hard disk. After the partition table is written you still need to declare/format/initialize your partition with a filesystem (XFS, JFS, ReiserFS, etc) and do so with a 'mkfs' type command.

it does sound like you missed a step
assuming you want to partition your first drive
fdisk /dev/hda will open fdisk on /dev/hda
you can press m to get the help screen
you may have to delete some partitions you have already created and didn't/don't want
so press p to print the current partition table to the screen
it should list what is there, if you need to delete a partition
press d it will then ask you which partition you want to delete
it will ask "which partition [1-4]" that's just the number of possible primary partitions, /dev/hda1 would be your first partition, /dev/hda2 would be your second. /dev/hda3 your third. etc...
you can delete them all if you'd like, one at a time
to create a new partiton press n it will then ask you something about extended or primary ( doing this from memory so I'm not sure exactly how it asks
press p to select a primary partition
it will then ask what size...I hope you had already decided what size and which order you wanted your partitions.
I have my swap first ( since it's used by another distro on another disk)...so say you wanted a 128 meg swap space type +128M
it will then ask you where you want it to start the partiton I usually accept the default since its the first space availabe...press enter and you have one partiton of 128 megs
press p to print the table to verify it
the press n again for a second partition
press p for primary
let's say this is for your /boot partition so we'll keep it smallish
lets say +75M and if you want to start iright next to your first partition then accept the defaults
press p to print the table and verify
the rest of your HD can be used for / or whatever part of it you would like
press n again....p for primary and if you want to fill up the remaiming part of the HD just accept the default
press p one last time to verify that you have 3 partitions
then you must press w which will write (create) the partition table
and exit fdisk
To put a filesystem on your partitions you then use
mkswap /dev/hda1 assuming your first partition is your swap
and either mke2fs /dev/hda2 to make an ext2 filesystem on what you want to be your /boot partiton or mke2fs -j /dev/hda2 for an ext3 filesystem
there are instructions in the install guide to get you thru this part
make sure to create a filesystem for all your partitons and to mount your swap, /boot/ and / partitons as described in the Install guide
...as I said this is from memory but it should be enough of a guide
to get you thru fdisk, just press m for the help menu if you forget something

Thanks Bonez,
I stand corrected.

I think we lost Ejoni on this one... no response since the original post.

That really sucks because hwbj did a great job explaining things. Hopefully, someone will find this in a search sometime.
