Red Hat Install Problems
hey guys
While trying to install RH8 i get this error report when trying to set partitins/formating them -" The Kernel was unable to re-read the partition table in dev/hdb (device was busy). This means linux knows nothing about the modification u have made."

I am trying to install in a old ata 33 HDD which I have made a slave in the Primary IDE connector. The mobo is Asus A7V333R and 1900+ Cpu. Its strnage because if i do proceed. it will go on its business of installing it. But i just can't boot into Linux.

I made partitions in Partition Magic 8. On the old HDD, 256 MB for /boot, 256mb for swap and the rest of the 4.3gb for / (or root).
and then I CD booted to install.

Any1 know what this is and how can i get round this problem?
Any help appreciated.

Hey Bud :)

You need at least 4 partitions :angel:


Note that swap should be the amount of RAM you have.
You don't really need boot (especially THAT large, 70 megs is enough). You don't need boot because you can install LILO (linux boot loader on hda, your first hard drive). This will boot both Linux and Windows :)

I don't know your system architecture but I've done some different LILO configs in past and putting LILO into MRB is the best thing IMO. Remember to have those 4 partitions :)

Unwritten "Rules"

So what kind of partitions should you make? It is always a good idea to make the swap partition first so you specify an exact size for it. It is also a good idea to make seperate partitions for /, /home, and /usr. People will tell you many things about how to divide up your disk, but it really comes down to what you want. There are many good reasons to breaking it up into /, /home, and /usr. For example:

Home directories are always on their own partition and you can upgrade the distribution without having to backup the home directories.
/usr is where software goes, so you can keep that whenever you upgrade distributions.
The root directory should really remain untouched, except for the modified files in /etc and root's home directory.
Others may tell you that you must have a seperate /var partition so log files won't fill up the root filesystem or so that the mail spool gets its own partition. Really, the choice is yours. Experiment with it, you can always change it later.

I assume you have ~4.5 GB HD (as you posted: 256 swap + 4.3 rest)

swap - should be really the amount of RAM you have. You can set it 100 megs less, it wont hurt the performance if you have 512. But if you have 256 MB of RAM make your swap partition 256 :)

/ - this is home dir for root, config files, logs etc. Make it about 1 GB

/usr - where all your programs go. You should probably make it around 2.5 GB's

/home - where your user files/configs/games may go. Make it 1 GB or whatever it's left

BTW which Redhat version ?
