Trying to install Mageia 3 to LVM

[Bequimao]

Hello all,

Im a trying to install Mageia 3 to a logical partition of an LVM. By custom, I use the full DVD Mageia-3-x86_64-DVD.iso. Is it possible at all with this installer? I missed the option to choose between grub Legacy and Grub2, and where to install the Bootloader. I dumped to ISO to a pen drive (command dd). I put everything into one partition, no separate /boot or /home.

The installation runs to a point after configuring root and user
Preparing bootloader ...
Internal error sdb10 ... unknown device ...
There is no sdb10 on my hard drive.

Best regards,
Bequimão

Hi, I found now that the selection which grub would occur later.

The messages look very similar to this bug-report: https://bugs.mageia.org/show_bug.cgi?id=9011
although here is no encryption involved.

I will now test an installation from a live system and try to catch the messages.

Some system info

I would suggest you to create /boot partition (200MB or so) and then LVM. Or choose grub2 as your bootloader, that should work too.

I would suggest you to create /boot partition (200MB or so) and then LVM. Or choose grub2 as your bootloader, that should work too.

It doesn't matter, if I create a separate boot partition or not. And as I quoted before, the error occurred before one could choose between grub2 or grub Legacy. Just now I tested the installation with Mageia 4 alpha 1 (KDE amd64, live usb). The installer terminated before configuring root and user, or grub - I didn't see how. But I could start the kernel with grub2 from another linux installation. Then the configuration of all packages started, I configured root and user, rebooted and could even install grub2 in mcc. I guess that I have now a working complete installation of Mageia 4 in the virtual partition of LVM.

Next step, I tried to reproduce the original issue with Mageia-4-alpha2-x86_64-DVD. The bug is still active, it doesn't even matter, if I install to the logical partition of LVM or to another partition. Just the presence of my LVM only leads to the permanent loop.

The message begins with: Prepairing initial startup programs ...
and then

Code: Select all

Internal Error: Unknow device sdb10
MDK::Common::Various::Internal_Error called from /usr/lib/libDrakX/devices.pm:186

There is no sdb10 in my system. When I accept the button OK, than it starts again: Prepairing initial startup programs ...
By the way, the German translation "Initiale Systemstartprogramme vorbereiten ..." is more than awful.

I will attach my report to the original bug report.

Hi all,

I just have a hint what might have happened
Please have a look at
epidemic-4.1-b1-1-amd64.iso is nearly ready for USB stick

...
I myself had to do another change, due to a peculiar hard
disk layout and the mount-facility in your system.

This command stalls forever on my test machine

Code: Select all

mount -o rw -t ext3 /dev/sda15 /mnt/device

The machine has seen several failed installs and some
successful ones of Debian GNU/Linux, FreeBSD, Solaris.
So the existence and state of /dev/sda15 might be an extreme
case.
Nevertheless, mount of Debian 6 does not stall but refuses,
because of ext3 journal problems.

This is exactly what happened on my machine. I used it as test machine for quite many distros. I hope that it gives a clue to somebody how to fix the issue. There are some other bugs with similar error messages. I am nearly confident that all those bugs hang together.

Best regards,
Bequimão
