Installation issue: after installing Ubuntu 9.10, it hangs on boot

[Mario Abajo]

Hello,
   I had the same problem even with 9.04 and in my case i found a
tricky solution. I have a motherboard with a fakeRAID soution based on
an
intel ICH10 but i prefer to use the software RAID that come to linux.
The problem is that the dm_raid45 module necesary to use fakeRAID that
i
"don't" activate during installation is really activate and in some
manner blocks the linux software raid. The solution in my case was
easy when
i got to find the problem :)
   - Boot from other media (i used the ubuntu alternative install cd)
   - Mount the root, the boot and proc partitions
   - chroot to the installed ubuntu
   - apt-get remove dmraid

In the process it re-make the initrd boot image without the tools and
modules of the dmraid and after rebooting it boots perfectly.

Hope it helps you.
Mario


| Hi @ll,
|
| I hope this is the correct platform to discuss my problem, otherwise
please point me in the right direction.
|
| I installed Ubuntu 9.10 (being new to Ubuntu, but not to Linux in
general). After finishing the installation (from an USB pen drive),
the
| installer told me to reboot. But the system hangs on boot with
merely a blinking cursor on the screen, no loader messages (I chose
grub2 as
| boot loader), nothing.
|
| Since the mainboard does not feature IDE ports and my SATA hdds seem
not to be willing to boot, I am only able to use USB pendrive for
| diagnostic purposes, for instance the Super Grub Disk. However, I
did not succeed to find any useful information to my problem.
|
| Could somebody give me a hint what I can do to either solve the
problem or at least diagnose it in more depth?
|
|
| Some facts:
| During Ubunut installation, I configured a software RAID:
| My 3 HDDs are partitioned having a 4 GB and a 1,5 TB partition each.
| Two of the 3 4 GB partitions are used a RAID1 system disk (root
filesystem), the 3rd as a Swap Area.
| The remaining three 1,5 TB partitions will then be used as RAID5 but
this is a second issue.
|
| Once again:
|   hda1 ... 4 GB added to RAID device #0 (RAID1)
|   hda2 ... 1,6 TB added to RAID device #1 (RAID5)
|   hdb1 ... 4 GB added to RAID device #0 (RAID1)
|   hdb2 ... 1,6 TB added to RAID device #1 (RAID5)
|   hdc1 ... 4 GB added to RAID device #0 (RAID1)
|   hdc2 ... 1,6 TB added to RAID device #1 (RAID5)
|   RAID device #0 ... ext4, mounted at /
|   RAID device #1 ... ext4, mounted at /data
|
| The BIOS boot sequence is: only from HDD (I disabled booting from
removable media or CD-ROM).
|
|
| Thanx a lot in advance,
| Andi
