Cannot upgrade from FC6->F7. No upgrade option given in install screen. (and RAID remnant)

[Lou Spironello]

Dear Jim:

Please forgive me for not responding sooner.  I began this reply the day you
sent me the message and got sidetracked.

Thank you again for your lengthy, well thought out, consistent and
technically
sound response!

I apologize if my responses were not clear.   I beg you for great
forgiveness.

Again, all me methods I've used and you've suggested have been taken
because I've been under the assumption that anaconda saw remnants
of past lvm or raid devices based upon the docs in the installation guide
and I believe in the release notes.

I thoroughly read the article at www.issociate.de.  I found a slew of
pointers
which I can possibly use in the future and I tried to use some of the mdadm
command suggested there.   however, since there are no physical partitions
associated
with the raid device /dev/md0 mdadm will not operate on that device.
Moreover
the partitions originally associated with the device have been deleted.

I've run find on my udev directories looking for "md" but nothing appeared
relative
to raid devices.

I have also noticed a complete md0 tree located in /sys/block/md0 and I
suspect
that anaconda might be reading that and thinking that an raid device exists.

re: the 4GB split on files.
I'm assuming that was mentioned with the intent to burn to a DVD.
I don't have a DVD burner nor a CD burner on my linux box.  My cd
burner died a while back and I'm only using a CD reader.  I only have
a CD burner on an older windows box.

Thanks for the info regarding the incremental label naming of paritions, i.e.
/usr1 etc.

Re: the reference to the f7-updates.img.
it apparently found it across the net when I specified it
on the command line since anaconda prompted me for the IP address
of this local machine along with the gateway and dns which were both my
local
router.  I'm assuming that since I didn't receive an error after that that
the f7-updates.img file was used but I'm only guessing.

Again please forgive me.  The fstab I included in the previous e-mail did
not have label
references for partitions on drive /dev/hdc or /dev/hdd even though
partition labels
do exist for all parititions.

Well, I changed the physical device references for all partitions on
/dev/hdc and /dev/hdd,
neither of which have any OS software, and voila!  I rebooted with the
rescue
CD and I eventually received the install / upgrade window!  Hmm.  I think
there should be some mention in anaconda as an informational message
or as an error message flagging that as a potential "non-install" issue.

The upgrade continued from there until it reached the
selinux-policy-targeted rpm
at which point it appeared to have stalled.  I checked the drive light and
apparently
there was disk activity and I assumed that selinux-policy-targeted was
changing file
attributes or assembling policies for selinux, so I waited.  I was tempted
to do
a hard reset but I resisted.   1 1/2 hours had already passed and the
install was
not finished yet.  More than 2 hours later and the install finally
finished.  The machine
rebooted and I received an error, in that it couldn't find my F7 install.
So I rebooted
again and explicitly selected the F7 option from the grub boot menu (there
was only
one other entry, that of the FC6) and the F7 boot continued from there.  I
was then
presented from pirut with over 975 upgrade packages.  So  I spent most of
Sunday
wading through those.  I'm now checking through the package manager to
ensure
check for other installs.  I still have to wade through my rpm list for
legacy fc6 rpms
that F7 didn't remove.

Thanks very much for your help.

Regards,
Lou
