Hi all,
I realise this is the gentoo forum, but I've had this problem out on the sabayon forum (which is not as busy as here) and got no feedback as yet. So, I'mputting my question out here as well.

I just went to upgrade to 3.4 loop 1 (live/install DVD) and it won't detect my existing Sabayon 3.3 installation.

Simply put the 3.4 DVD doesn't load or recognise my s/w RAID sets. Therefore it can't find my existing installation and wants to re-partition the disk by default.

Here's some info from my running 3.3. system to see if it's a contributing factor:

=======================================

I've done a bit more research on this and if I load the raid sets manually in a terminal before running the installer it finds them - then aborts!

Here's the commands to find them (causes mdadm to look for valid raid partitions on all devices)
mdadm -Ebsc partitions

If they look ok do
mdadm -Ebsc partitions >/etc/mdadm.conf
to write a conf file

then
mdadm -A --scan
to read the conf file and start the raid sets.

Now I run the installer. It fails on an /etc/fstab mounting error.

Now /dev/sdg is just a usb stick and when I re run the installer without it installed it still fails on an /etc/fstab mounting error. I've also tried this on the Sabayon 3.3 dvd and get the same results as above.

Any advice on how to resolve this one?

Thanks Russ
