System: * Ubuntu 8.10 amd64 (not installed yet) * Intel Software Raid from ICH9R southbridge, ASUS P5K-E motherboard * 4 hard disks with two raid arrays (one RAID0 array and one RAID5 array).
I am trying to install Ubuntu Intrepid on the fakeraid but none of the solutions worked for me. Dmraid fails with this error (repeated 8 times, one time per disk and array): ERROR: isw device for volume "zerovol" broken on /dev/sda in RAID set "isw_baeaijeeda_zerovol" ERROR: isw: wrong # of devices in RAID set "isw_baeaijeeda_zerovol" [8/4] on /dev/sda I have tried these: * Solution to the live CD. I have tried booting with break=top and adding /etc/modprobe.d/libata-options and with /etc/modprobe.d/options but dmraid prints the same error message. * Using a USB persistent startup disk. I have changed /etc/modprobe.d/libata-options and /etc/modprobe.d/options and rebooted, the changes in that files are permanent, but dmraid fails. So I have followed a workaround to be capable of executing "update-initramfs" without "You are executing from a live CD" limitation. (see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/292159) I have copied the output initrd.gz to the flash USB stick on /casper/initrd.gz, but dmraid still fails. Any ideas on how to install Ubuntu to a RAID5 without any other hard disk outside the raid arrays? I have an older Ubuntu 8.04 already installed and working on the raid0 and capable of read/write the raid5 array, it could help. Regards. NOTE: with Ubuntu 8.04 release candidate dmraid works wells, but raid5 kernel module had incorrect name, so I could not install. With Ubuntu 8.04.1 module had correct name, but dmraid did not work well, so I could not install. With Ubuntu 8.10 kernel module is correct, but dmraid has another problem. I cannot remember which stupid think failed in Ubuntu 7.10. Conclusion: Fakeraid support is too poor, raid is wide extended even in desktop users. We need better support please!! -- HPA ( Host Protected Area ) interferes with dmraid https://bugs.launchpad.net/bugs/219393 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
