Hi there,

I'm following along with the example in Software RAID Configuration in Chapter 24, but something weird is going on...

I created my disk as instructed, and it worked and md0 was created etc etc, but upon rebooting, RAID works... but is showing up as /dev/md127 instead of /dev/md0. Minor issue but really annoying...

wings@lfcs-ubuntu-srv:~$ sudo cat /proc/mdstat
Personalities : [raid1] [linear] [multipath] [raid0] [raid6] [raid5] [raid4] [raid10]
md127 : active (auto-read-only) raid1 sdc1[1] sdb1[0]
      8382400 blocks super 1.2 [2/2] [UU]
        resync=PENDING

    I figured it out. Once you add the array to /etc/mdadm/mdadm.conf (on Ubuntu), you must run "update-initramfs -u" as instructed by that file. Then it comes up as md0 instead. Solved!

    Pretty well! I'm glad you solved it.
