[SOLVED] Upgrade from Mageia 2 to 3

[RoyD]

As the docs suggested it says to make sure that device map and menu.lst points to Sda. Mine is sdd. I have 4 physical drives so I thought I would remove the drives /backup, /vmm and /driveb. Mageia failed to boot correctly it went to terminal with the words Emergency words ending in ¨press Control D etc.¨ So I put the drives back in and it booted up fine. I had this problem several times before eg terminal Emergency words ending in ¨press Control D etc ¨with upgrades. I believe I have some thing wrong from the start and it would be good to fix this problem so the upgrades are easy (relative) , and they should be. Should I have the Home,root,swap drive in sata 1 or does it make no difference?
To upgrade I have tried several times with adjusting the fstab , un-mounting the drive then disconnecting the cable but I keep coming back to terminal Emergency words ending in ¨press Control D etc.¨
I wonder if I can fix this for once and for all, so I can upgrade that is not a pain in the a. I do use Mageia as my main system. I don't mine starting from scratch?. Any suggestions would be most appreciated. The following is details is before changes. Thanks Roy

Did you remove the drives physically, meaning you unplugged them? Please only comment them out in your /etc/fstab, change as follows:

# Entry for /dev/sda1 :
UUID=6bf0e665-4a3c-4cbb-83fb-160e1a07a2cd / ext4 acl,relatime 1 1
# Entry for /dev/sdc1 :
#LABEL=backup /backup ext4 defaults 1 2
# Entry for /dev/sda6 :
UUID=4afe422f-47ac-48fe-b8e2-286eb0a0e1c5 /home ext4 acl,relatime 1 2
#/dev/sr0 /media/cdrom auto umask=0,users,iocharset=utf8,noauto,ro,exec 0 0
none /proc proc defaults 0 0
# Entry for /dev/sda1 :
#UUID=86cebd0f-f126-4d48-9499-5afd46e01745 /vmm ext3 defaults 1 2
# Entry for /dev/sda5 :
UUID=824109d0-5dbb-4a12-a37b-36c9ccf568de swap swap defaults 0 0

Also better comment out the cdrom entry, that's not needed and may cause some problems later on during normal use with the CD/DVD drive.

Thank you doktor5000
The instructions really worked well. All drives are now all reconnected back by their sata leads. Changed my Fstab back to orginal (except for the rem on the cd). The distro looks really good. Thanks everybody for producing a fine distro.
Cheers Roy
