View Full Version : F11 on ICH10R raid 0

Hello

First of all - I'm not experienced in linux systems.

I tried to install F11 on a P5Q Turbo MB with 2x1Tb Seagate Hdds - the raid is set from bios.
Southbridge ICH10R controler is used.
The partitions are like this:

100Mb - primary for boot
200Gb - Xp - primary
the rest is a extended partition
=====================
200Gb - vista - logical
700Gb - storage1 - logical
700Gb - storage2 - logical
95GB - ext3 for /
4gb - swap
=====================

The partitions for fedora were already made with a windows tool prior to this install.
I only choose to format them from the installer to ext3 format and swap.

In the installer the raid is well seen as mapped in /dev/mapper/isw_ideagdggg_Volume0.
Partitions are like /dev/mapper/isw_ideagdggg_Volume0px.
The install is working well, I select the GRUB to go in MBR.

After install at the first boot, I simply get the Vista loader screen as before install.
If I boot in rescue mode from the dvd to the linux install I can see that there is in fact no /etc/fstab file.
With a fdisk /dev/mapper/isw_ideagdggg_Volume0 I see something curious, /boot, / and swap partition are seen as FAT16 (!)

If I make a fdisk on /dev/md-0 I see the same FAT16 /boot, / and swap partitions but in this case, the partitions are displayed like /dev/dm-0px but in /dev/ there are actually /dev/dm-x files for partitions.

On grub, I fail to root, with the unknown partition type problem either if I use the /dev/mapper files or /dev/dm-0 ones.

To me, it looks like there is an incompatibility problem betwee dmraid and mapper modules... (just my opinion :) )

1) Would be ok if I make some symlinks in /dev/ for dm-0 files?

2) Did anyone managed to install F11 on existing raid 0 array?

3) From what I've understood mdraid is better than dmraid, at least for isw_ controllers - is there a way to use this instead of dmraid at install time?

I would be interested to see how this pans out. I also was running RAID0 on an ICH10 raid controller, however Anaconda crashed every time it got to the detecting drives section of the installer. Taking out the RAID0 was the only thing I could do to make it work, however I might have one drive that is failing, as the installer only saw 2 of the three total drives in the system (750GB storage drive, 2x320GB RAID drives).

Good luck, you got farther than I did.

For me it worked this way:
- intstall first the Fedora 9 with basic configuration
- then install over it Fedora 11 - format all partitions(linux only) (not upgrade) and do not re-partitionate with F11 anaconda

That's all
I found this clue on a web page that I don't remember now...

or maybe this one:

The 2nd of the two is the better of the two. It applies to F10, F11 and F12.
Your mileage may vary.

I've also posted this info in some of my many bug reports on bugzilla.

I'm using ICH10 and RAID0 -- but Linux software RAID rather than BIOS RAID.

I boot from sda1 and have / on the RAID.
