Guest !Xi! Posted January 25, 2007 Report Share Posted January 25, 2007 Hello I'm planning switching to Linux from Windows and chose Mandriva 2007 Free to be my new OS. I have an ASUS A8V Deluxe motherboard with VIA VT8237 which provides RAID funcionality on SATA drives. During installation process the installer recognizes my RAID setup and asks me if I want to enable it. I answer yes and the partition is available to even install on it. I choose anohter partition on an ATA HDD. Everything goes fine but my problem occurs after successful installation. The partition is not mounted and cannot be mounted. /etc/fstab refers to /dev/mapper/via_dhgdggdbbd5. When I look into /dev/mapper there is only one file: control When I use Knoppix the RAID is recognized and the partition is mounted normally. Any hint about things to do would be much appreciated Quote Link to comment Share on other sites More sharing options...
Ixthusdan Posted January 25, 2007 Report Share Posted January 25, 2007 Does Harddrake report the RAID partition, only unmounted? Configure My Computer=> System=> Hardware, I think! ;) Quote Link to comment Share on other sites More sharing options...
Guest !Xi! Posted January 25, 2007 Report Share Posted January 25, 2007 (edited) Thanks for the reply Ixthusdan The system sees both RAID HDDs as seperate ones and they are unmounted (this is normal sisnce fstab doesn't mount them seperately) When installing Mandriva I was presented with w single RAID HDD after is discovered that I'm using it and asekd if I want to enable RAID. SATA RAID controller is present in the system. Edited January 25, 2007 by !Xi! Quote Link to comment Share on other sites More sharing options...
michaelcole Posted January 26, 2007 Report Share Posted January 26, 2007 We did the same here. We have two HDD mirrored using a ASROCK motherboard THe things we did. Set up raid first Do a full reboot, (the Raid has to set it self up on boot.) Then start the install, install notices raid and asks, SAY yes. Next install it all. After double check where it is trying to install the grub or lilo. Then you shoud be ok. In our case it was trying to install the Grub on my USB Drive, (Where i have the installers.)

Guest !Xi! Posted January 26, 2007 Report Share Posted January 26, 2007 Thanks for the tip, michaelcole. Does it mean that I have to install a software RAID? Could you help me with some specyfic commands? How do I install RAID? Won't I loose data already on RAID partitions? Quote Link to comment Share on other sites More sharing options...
michaelcole Posted January 26, 2007 Report Share Posted January 26, 2007 (edited) Ours were all blank.. But the question from mandi is "should it use the RAID as setup and use the software driver to talk to the RAID setup" Still using the hardware BIOS raid.. Once you are past that question it asks about the partitions there you can specify what you want to do, we selected the bottom option "advanced or custom" not sure what it is but it gives you a display of what partitions you have and what you can do with them. IF YOU HAVE PARTITIONS IT WILL SHOW THEM THERE... We split ours 250GB into 100GB /home/ 30GB for /var/www 40GB for / 4 GB for swap 50 GB for our RSYNC directory (we rsync external mandy site for easy and quick installs internally) 30 GB for /var/ this allows for logs to build up and not disrupt other functions Up to personal preferences for the patitions.

Guest !Xi! Posted January 26, 2007 Report Share Posted January 26, 2007 Can I do this having the OS installed or should I reinstall? If yes, what app should I use? Thx in advance for your help Quote Link to comment Share on other sites More sharing options...
ianw1974 Posted January 26, 2007 Report Share Posted January 26, 2007 Software raid can be configured on an existing system, or it can even be configured before installation. However, if you are using raid for a hardware raid controller, then it has to be set up before you install the operating system. EDIT: Installing software raid mirror - RAID1: https://mandrivausers.org/index.php?showtop...l=software+raid Converting existing system raid mirror - RAID1: https://mandrivausers.org/index.php?showtop...l=software+raid the first exists on my website as well. The second will exist on my website over the next few days when I get it updated. They both work for me, which is why I wrote them :P Quote Link to comment Share on other sites More sharing options...
Guest !Xi! Posted January 27, 2007 Report Share Posted January 27, 2007 Thanks for all the help. I discovered that all it takes is a simple dmraid -ay to be able activate the array and mount /dev/mapper/via_dhgdggdbbd5 It seems that dmraid is never activated when booting. How can I activate it automatically every boot to be available before /etc/fstab is processed? Quote Link to comment Share on other sites More sharing options...
