Hi all, Since 2.6.8.1 + kernels, the kernel is unable to find my raid arrays. I have searched and found that riadstart is deprecated and broken. (raidstart is what suse uses by default), I have since installed upto date mdadm tools, and tried setting up a /etc/mdadm/mdadm.conf with my raid drives, and also reruning mkinitrd for my new kernels with root specified. But the kernel still refuses to boot my root partition. I boot off a non raided partition sda1 and also have swap on a non raided partition sdb1. My raid setup is as bellow: ARRAY /dev/md1 level=raid0 num-devices=2 UUID=da49e3b8:d0b65de4:7817e388:54c4980d devices=/dev/sda3,/dev/sdb3 ARRAY /dev/md0 level=raid1 num-devices=2 UUID=3702dbfc:1572856f:4f673190:fc5212c4 devices=/dev/sda2,/dev/sdb2 Now I've tried using a number of howto's with sata raid root etc, but nothing seems to work. This is what the last functioning kernel that boots, boot process looks like: ata1: SATA max UDMA/133 cmd 0x9800 ctl 0x9C02 bmdma 0xA800 irq 20 ata2: SATA max UDMA/133 cmd 0xA000 ctl 0xA402 bmdma 0xA808 irq 20 ata1: dev 0 cfg 49:2f00 82:74eb 83:7fea 84:4023 85:74e9 86:3e02 87:4023 88:203f ata1: dev 0 ATA, max UDMA/100, 321672960 sectors: lba48 ata1: dev 0 configured for UDMA/100 scsi0 : sata_via ata2: dev 0 cfg 49:2f00 82:74eb 83:7fea 84:4023 85:74e9 86:3e02 87:4023 88:203f ata2: dev 0 ATA, max UDMA/100, 321672960 sectors: lba48 ata2: dev 0 configured for UDMA/100 scsi1 : sata_via Vendor: ATA Model: HDS722516VLSA80 Rev: V34O Type: Direct-Access ANSI SCSI revision: 05 Vendor: ATA Model: HDS722516VLSA80 Rev: V34O Type: Direct-Access ANSI SCSI revision: 05 SCSI device sda: 321672960 512-byte hdwr sectors (164697 MB) SCSI device sda: drive cache: write back sda: sda1 sda2 sda3 Attached scsi disk sda at scsi0, channel 0, id 0, lun 0 SCSI device sdb: 321672960 512-byte hdwr sectors (164697 MB) SCSI device sdb: drive cache: write back sdb: sdb1 sdb2 sdb3 Attached scsi disk sdb at scsi1, channel 0, id 0, lun 0 mice: PS/2 mouse device common for all mice gameport: pci0000:00:08.1 speed 1187 kHz serio: i8042 AUX port at 0x60,0x64 irq 12 input: ImExPS/2 Generic Explorer Mouse on isa0060/serio1 serio: i8042 KBD port at 0x60,0x64 irq 1 input: AT Translated Set 2 keyboard on isa0060/serio0 i2c /dev entries driver md: raid0 personality registered as nr 2 md: raid1 personality registered as nr 3 md: md driver 0.90.0 MAX_MD_DEVS=256, MD_SB_DISKS=27 device-mapper: 4.1.0-ioctl (2003-12-10) initialised: dm@uk.sistina.com Advanced Linux Sound Architecture Driver Version 1.0.4 (Mon May 17 14:31:44 2004 UTC).

Help! I need keep testing kernels but I can't continue with this fooked up raid.. BTW: This is related to this message: raidstart(pid 473) used deprecated START_ARRAY ioctl. This will not be supported beyond 2.6 Any help and comments are appreciated... A step by step howto do this would be helpfull. Kind regards Joel W New Zealand
