Re: Mdadm not starting at boot

you know I had/have the same problem ...

I finally broke down and wrote my own init script that I run in
runlevels 2-5 that basically has 

mdadm -A -s
vgchange -A y

And then my mounts in it ... I run it as an S19 so it starts right
before Samba and NFS which are what my raid array exports.

As for the bad superblock, it could be a hardware problem, or it could
be the power issues you've had ... if it persists even with clean
shutdowns, I'd start looking at the hardware.   Hope that helps.
