Dear, I have a system with the following raid setup: root@astra:~# df Filesystem 1K-blocks Used Available Use% Mounted on /dev/md_d0p1 3906116 3712624 193492 96% / /dev/md_d0p3 976476 32848 943628 4% /tmp /dev/md_d0p5 488236 55208 433028 12% /var/log /dev/md_d0p6 3906116 3630292 275824 93% /usr/src /dev/md_d0p7 7666192 42128 7624064 1% /home root@astra:~# cat /proc/mdstat Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] md_d0 : active raid1 sdb1[1] sda1[0] 17920384 blocks [2/2] [UU] The unit boots over ethernet, with the following stansa in pxeconfig: default astra-2.6.27.6 noinitrd load_ramdisk=0 prompt_ramdisk=0 root=/dev/md_d0p1 raid=part ro prompt 1 timeout 1200 display astra.f1 F1 astra.f1 So far, so good. Now as soon as i switch to kernel 2.6.28.2, it fails and the kernel is not able to find the root device. Anyone an idea what is happening here? relevant section from config: CONFIG_MD=y CONFIG_BLK_DEV_MD=y CONFIG_MD_AUTODETECT=y CONFIG_MD_LINEAR=y CONFIG_MD_RAID0=y CONFIG_MD_RAID1=y CONFIG_MD_RAID10=y CONFIG_MD_RAID456=y CONFIG_MD_RAID5_RESHAPE=y # CONFIG_MD_MULTIPATH is not set # CONFIG_MD_FAULTY is not set CONFIG_BLK_DEV_DM=y # CONFIG_DM_DEBUG is not set # CONFIG_DM_CRYPT is not set # CONFIG_DM_SNAPSHOT is not set # CONFIG_DM_MIRROR is not set # CONFIG_DM_ZERO is not set # CONFIG_DM_MULTIPATH is not set # CONFIG_DM_DELAY is not set # CONFIG_DM_UEVENT is not set # CONFIG_FUSION is not set Cheers, Rudy -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
