Keeping debian from auto-assembling

Keeping debian from auto-assembling

[Dexter Filmore]

I'd like to assembla manually to investigate why the bloody 5th disk flies 
from the array at EVERY boot time (third so far, wonder how much stress the 
disks take) but I can't seen to disable it.

All 5 disks are 0xFD, but I passed raid=noautodetect to the end of the kernel 
line, I set "assemble at startup" in /etc/defaults/mdadm to "false", I 
cleared the mdadm.conf - still it assembles the array. No idea why.

Hints? I'm currently pretty much down with my nerves on this issue.

initrd or udev?

Since you shutdown and booted another distro to see == Events then it's not a
bad shutdown process.

On reboot it looks like something is assembling the array partially.
I'd upgrade udev, then test and then upgrade initrd-tools.

you need to rebuild your initramfs after you make those changes to 
/etc/defaults/mdadm ... easiest is:

dpkg-reconfigure linux-image-`uname -r`
