Re: FW: Kickstart partition woes

Nope, that's not the issue, I'm, beginning to lose hope :o(
I have just about exhausted all different options in the partition section.
Is there nobody that has tried doing this before, it seems like something
that should be easy to do.


All of my attempts have been stabs in the dark, really, Gordon.  I don't
do kickstart installs very often.

It is entirely possible that kickstart doesn't support reusing existing
software RAID devices without reformatting.  I don't see such a
restriction in the docs, but that doesn't mean much.  You might try
checking the bugzilla archives at bugzilla.redhat.com to see if someone
else has run into this and if there's a fix or work around.  If not,
you may have to do the thing manually.  I know it's a pain if you're
doing a network install, but that may be your only recourse.

Sorry I couldn't help more.

Thanks for the reply, to answer your questions, yes it's software raid and
yes /home was on md3, I cannot see why I should not be able to do this new
install since if you try a manual install then you can see all the
partitions and raid devices and the only thing that needs done is to

relabel

the raid devices to reflect the partitions and tell it whether to format

the

raid device or keep the data intact. 


Erp!  I think I found it.  Your lines specifying the RAID layout are
missing some stuff.  In your "raid" lines, I think you must have
"--fstype=ext3" rather than "--fstype ext3".  This may be an issue as
the other partitions are going to be formatted (and ext3 is the default)
while /home is NOT going to be formatted.  I'm surprised it worked at
all with spaces instead of "=" in those lines.  I'd expect some errors
regarding "can't find device ext2" or "can't find device ext3" in the
other lines as well.

Hi

I recently sent the following email to the general Redhat list but got no
reply, I was hoping that someone on this list might be able to help
out...please!

I am currently trying to upgrade a server from Redhat 7.2 to Redhat
Enterprise 3.0, the server is running raid and I would like to keep the
/home partition intact and basically do a full install on the remaining /
/boot and /var partitions.   When I try the install it always errors out
with the error "unable to locate raid device None for /home" but as far as

I


can see the partition section of the kickstart file is fine, does anyone
have any suggestions as to what may be the issue.
Here is a copy of the partition section of the ks.cfg file

#Disk partitioning information
part raid.01 --onpart sda1
part raid.03 --onpart sda2
part swap --onpart sda3
part raid.05 --onpart sda6 --noformat
part raid.07 --onpart sda5
part raid.02 --onpart sdb1
part raid.04 --onpart sdb2
part swap --onpart sdb3
part raid.06 --onpart sdb6 --noformat
part raid.08 --onpart sdb5
raid /boot --level=1 --device=md0 --fstype ext2 raid.01 raid.02
raid / --level=1 --device=md1 --fstype ext3 raid.03 raid.04
raid /var --level=1 --device=md2 --fstype ext3 raid.07 raid.08
raid /home --level=1 --device=md3 --fstype ext3 --noformat raid.05 raid.06


Thanks, any suggestions appreciated 


So, this is a software RAID?  Which device is /home on under 7.2?  From
your ks.cfg file, I'm guessing it's md3 (raid 05/raid 06).

I'm not at all certain you can do an upgrade from 7.2 to ES3 on software
RAID without reformatting.  First, that's one hell of a gear change
(jumping three major releases)  Second, the mechanisms used to support
software RAID changed quite a bit over that time.  I think you're going
to have to back up /home to some media somewhere and let the system
format /home to get past that.

Wish I could help more.
