[opensuse-factory] First install went well, but raid1 bootloader problem?
My first installation went without a hickup and everything looks good, after a quick glance anyway. Thanks!! I left the grub settings at the suggestion made by yast. root fs is /dev/md2 (it's a spare partition). Boot loader was installed to md2. System bootet fine - with the grub menu from the 10.2 installation on that system (which I had forced into mbr). Does this mean there would have been nothing much but a black screen on first boot had the previous boot loader not been there? How many people boot from a Linux software raid1? The booting works fine, but few releases of 8.x, 9.x and 10.[012] do install it functionally in my experience.

Hi, I installed 10.3 onto a 8 drive combo HW and MD raid. I have been beta testing and found I needed to regress to kernel .25 other than that it is GM. I needed to go back to .25 kernel due to the driver for the HW raid controller driver which hasn't caught up to all of the changes yet <frown> . I am running off of pure MD raid partitions for the Linux OS including the MBR, /boot and / (root). If you are interested, I've included links to screenshots of the partition table, fstab and GRUB setup for this installation. There is no external partition used to boot as everything is contained in the MD raid structure. The swap is raid 0, the boot and root are both raid 1 and home is raid 5. The HW array /raidbox is also raid5 and formatted ext3. Version 10.2 was the first SuSE version to support installation to MD software raid I believe. One problem remains, a serious one: The repair function doesn't know squat about fixing a MD raid installation if it has a problem, so you are kind of on your own if it breaks, but it is being worked on.

Me too. Safed by bacon twice already, and makes disk upgrades very painless (I only use raid for / and /home, but not /bigphat).

Oh no! 8.x installed / to md0 just fine, but one had to watch where yast wanted to put the boot loader (mbr always worked). While other distros were giving intricate spiels about how to boot from md raid, SuSE just did it (if you told yast mbr). Some versions 9.x were even able to install grub on each of the 2 raid1 disks. The limitation in 8.x was that yast could only create md0, but it would install on multiple mdX partitions if they already existed. The boot loader GAUs however have turned this fine piece of engineering into something not really usable by non-geeks. :(( Volker -- Volker Kuhlmann is list0570 with the domain in header http://volker.dnsalias.net/ Please do not CC list postings to me. --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
