On reboot the last disk to be added to the array is kicked out of it and the array starts in degraded mode. Long story: My setup is with six disks on a Promise TX4 serial ata controller. I have a working system on one of them, and am trying to set up a working RAID setup on the other five (leaving the first one as a spare). The 5 disks are each partioned into two; a 50 MB boot partition and a ~200 GB RAID partition. The RAID partitions are then run in RAID 5, then I run LVM on top of RAID. As my root I would like to use a LVM root partition. I've sucessfully used Debian's mkinitrd to create an initrd that has root-on-LVM support, and the system boots fine. However, the last disk that I added is never present in the array after a boot. I know that it is not a disk failure because there are no log messages about such a failure and also I've tried adding the disks in different orders, and it is always the last one that fails. After booting I can re-add the disk to the array, and after syncing it will operate as part of the array until the next reboot, when the same disk is kicked out again. However, when booting with the root from the original disk that is not a part of the array, it will recognize all five disks in the array without any problems. I'm running Debian testing, and the filesystem is ReiserFS.
