Re: partitioning in %pre

[james oden tekelec com]

James,

What version of RedHat are you using.  RH 9.0 has a couple of problems in
this
area:
      1) it does not  installing over the top of pre-existing raid devices
                   and trying to setup raid very well (think python
exception).
      2) It does not handle installing over the top of prexisting raid
devices, and
          not using raid (think of it using the wroing devices when it
mounts things;
          seems to prefer raid devices to non-raid devices).

The answer to one is to tell mdadm to clear the raid superblock, and use
tune2fs to clear the filesystem label.  The answer to the second problem is
all of the above, but to also clear the non used drives partition table.

There was a long question about this on the anaconda list recently but it
got no response.

Cheers...james

I'm trying to setup a 50MB partition in %pre that will house the Compaq
System Partition.  Here's what I've got so far:

####
%pre

#create the disk device

mknod /dev/cciss/c0d0

#wipe out current disk

echo | fdisk /dev/cciss/c0d0 << EOF
o
w
EOF

echo | fdisk /dev/cciss/c0d0 << EOF
n
p
1

+50M
t
1
12
w
EOF

###

Unfortunately when I do this, anaconda fails when it tries to partition the
disk.

Any pointers?

Thanks,
