There's a script called /lib/rcscripts/addons/raid-start.sh. In there, create_devs() { local d for d in $@ ; do d=${d/\/dev\/} [[ -e /dev/${d} ]] && continue mknod /dev/${d} b ${MAJOR} ${d##*md} >& /dev/null done } is used to create any missing md device nodes at startup. It is assumed that the device name is /dev/md<number> where <number> is the minor number. However, devfs is using /dev/md/<number>, so in case this function has to create the device node, it fails as it cannot use the string /<number> as a minor number. Suggested fix: create_devs() { local d for d in $@ ; do d=${d/\/dev\/} [[ -e /dev/${d} ]] && continue minor=${d##*md} minor=${minor##/} mknod /dev/${d} b ${MAJOR} ${minor} >& /dev/null done } This way it would work with both /dev/md<number> and /dev/md/<number>. Reproducible: Always Steps to Reproduce: Use devfs, configure it to be mounted automatically at boot. Create a RAID device that does not get auto-started. For example use this configuration to create a RAID-0 stripe set - 9 - from two RAID devices (I used two RAID-1 groups - 7 & 8 - that do get auto-started): raiddev /dev/md/7 raid-level 1 nr-raid-disks 2 chunk-size 32k persistent-superblock 1 device /dev/sda8 raid-disk 0 device /dev/sdc8 raid-disk 1 raiddev /dev/md/8 raid-level 1 nr-raid-disks 2 chunk-size 32k persistent-superblock 1 device /dev/sdb8 raid-disk 0 device /dev/sdd8 raid-disk 1 raiddev /dev/md/9 raid-level 0 nr-raid-disks 2 chunk-size 32k persistent-superblock 1 device /dev/md/7 raid-disk 0 device /dev/md/8 raid-disk 1 Then reboot. Actual Results: /dev/md/7 & 8 get auto-started (if the partition type is set correctly), however /dev/md/9 does not exist, and if it is included in /etc/fstab, it will not be mounted. * sys-fs/raidtools : [ ] 1.00.3-r4 (0) [ ] 1.00.3-r5 (0) [ I] 1.00.3-r6 (0)
sync up and re-emerge raidtools ive fixed this already
