My ongoing disk battle...
Hi, Markku,
I attempted to follow the instructions on the site you quoted here, but
the command e2fsadm is not on my system. I am running yum whatprovides
now to get it. Here is what I have done so far:
[root at localhost ~]# fdisk /dev/hdb
The number of cylinders for this disk is set to 36481.
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)

Does anyone else have anything to add to my process here?
I am still waiting for results of the yum whatprovides e2fsadm.
