Going through the RAID install sheet, it says that after you turn on block devices and RAID support in the kernel, upon reboot, you should see something like the following in /proc/mdstat: Personalities : [1 linear] [2 raid0] read_ahead not set md0 : inactive md1 : inactive md2 : inactive md3 : inactive However, I see: Personalities : [raid1] read_ahead not set unused devices: <none> The personalities makes sense (I only turned on RAID-1), but shouldn't the /dev/md0->4 be in that file?
