Hello, I have a greater problem with the 2.4.13 and the ataraid! But first my configuration: 2x4GB HDs mirrored partition1 is my root partition4 is my swap On an Asus P3BF, with a ATAPI CDROM at the intel BX IDE port. I want to upgrade the kernel 2.2.18 to a 2.4.13. For the 2.2.18, I got a Promise module, which created a scsi device sda1 of my mirror. Now I want to move to 2.4.13. I could not find a suitable Promise module for the kernelversion, therefor I tried to use the ataraid. Now my questions: 1. Had anyone tried to use the Promise modules with the kernel 2.4.13? 2. I couldn´t get the kernel up, if I used all the options mentioned in http://people.redhat.com/arjanv/pdcraid/ataraidhowto.html. If I set up this options: CONFIG_BLK_DEV_PDC202X - PROMISE PDC202{46|62|65|67|68} support CONFIG_PDC202XX_FORCE - Special FastTrak Feature CONFIG_BLK_DEV_ATARAID - Support for IDE Raid controllers CONFIG_BLK_DEV_ATARAID_PDC - Support Promise software RAID (Fasttrak(tm)) The kernel hangs (without a kernel panic) directly after recognizing the ide1, ide2 and ide3. But if I try to set it up only with: CONFIG_BLK_DEV_ATARAID - Support for IDE Raid controllers CONFIG_BLK_DEV_ATARAID_PDC - Support Promise software RAID (Fasttrak(tm)) The kernel will come up and my / resides on /dev/ataraid/d0p1. Is the howto outdated or have I a problem with my configuration? What are the options I should use? 3. I use GRUB as the bootloader, and I can only start my kernel if I tell grub, that my rootfs is on /dev/hde1 or /dev/hdg1. After the kernel came up, I got a / fs on ataraid/d0p1, but my data was only written on one disk. The mirroring wasn´t active! I´m sure this point is not a issue of this mailinglist, but maybe someone had a similar problem. Hope you can help! Best regards, Darko
