Description of problem:
When trying to upgrade my RH8 installation to RH9, after I choose manually
partition with disk-druid, I get the following message

"The partition table on device /dev/hda is of unexpected type loop for your
architecture. Do you want to reinitialize the drive?"

/dev/hda6  is the /home & /dev/hda7 is the / of my RH8 installation.

My partition table looks like

Disk /dev/hda: 255 heads, 63 sectors, 3737 cylinders
Units = cylinders of 16065 * 512 bytes

   Device Boot    Start       End    Blocks   Id  System

How reproducible:

Steps to Reproduce:
1.Boot from cd
2.choose custom installation
3.choose manual partition

Actual Results:  partitions are not visible after the error message.

Comment 1 Michael Fulbright 2003-05-12 18:47:34 UTC
This would be something related to parted.

Comment 2 Pavan 2003-05-19 17:08:39 UTC
The output of parted /dev/hda print on the console provided by the installer
shows this
Disk geometry for /dev/hda: 0.000-29314.687 megabytes
Disk label type: loop
Minor    Start       End     Filesystem  Flags
1          0.000  29314.687  fat16       

Information: Don't forget to update /etc/fstab, if necessary.

I've Smart Boot Manager installed on my disk and that seems to be the problem.
When I remove SBM, parted recognises the partitions correctly. RH8 parted does
not have this problem.

Comment 3 Matt Wilson 2003-05-19 18:04:37 UTC
can you copy off the first 1024 bytes of your hard drive when Smart Boot Manager
is installed with:

dd if=/dev/hda of=part bs=1024 count=1

and attach it?

Comment 4 Pavan 2003-05-20 17:33:52 UTC
Created attachment 91832 [details]
The 1st 1kB of the hard-disk with SBM installed.

IIRC, SBM installs in the 1st 32kB of the hard-disk which is generally unused.
Also the SBM-parted problem seems to be reproducible on atleast one another
system I tried.

Comment 5 Matt Wilson 2003-05-20 18:12:10 UTC
great info.  I'll have a look.

Comment 6 Thomas Gebert 2004-03-11 16:03:02 UTC
I have the same problem upgrading a RH 7.1 / RH 8.0 to Fedora Core 1.
But my configuration is quite different :
The disk the installer complains about is /dev/sdb1, which is part
of a software raid device /dev/md0.
An upgrade from RH 7.1 to RH 8.0 was possible, but not to Fedora Core 1
and it's the same from RH 8.0 to Fedora.
My /etc/raidtab :
raiddev             /dev/md0
raid-level                  0
nr-raid-disks               3
chunk-size                  64k
persistent-superblock       1
#nr-spare-disks     0
    device          /dev/sdb1
    raid-disk     0
    device          /dev/sdc1
    raid-disk     1
    device          /dev/sdd3
    raid-disk     2
And a fdisk -l /dev/sdb shows :
Disk /dev/sdb: 42 heads, 61 sectors, 1023 cylinders
Units = cylinders of 2562 * 512 bytes
   Device Boot    Start       End    Blocks   Id  System
/dev/sdb1             1      1023   1310432+  fd  Linux raid autodetect

The other partitions, which are part of the raid device, are
also of type "fd  Linux raid". This RH installation is the only
installation on this system (no other OS).
What is the problem here ?
