Description Torsten Kurbad 2010-01-20 13:03:36 UTC 
With mdadm one is advised to no longer rely on kernel level autodetection of raid arrays, but to use mdadm --assemble instead. To accomplish this task, sys-fs/mdadm installs /etc/init.d/mdraid.

This script needs some adjustment, if you want to be able to properly use a raid array on bootup that has been encrypted using dmcrypt. In fact, it is vital that mdraid is being started before dmcrypt.

Find attached a patch to /usr/portage/sys-fs/mdadm/mdraid.rc that does just that and works for me.

Regards,
Torsten

some people do raid-on-dmcrypt while others do dmcrypt-on-raid.  there is no way to satisfy everyone.  if you need dmcrypt before raid, then set the dependency in your own conf.d file.  use rc_need as documented in `man 8 runscript`.

I wasn't aware of that option, or at least I got the wrong idea on how to use it. Works like a charme now, thank you!

ive added a tip to the conf.d file about rc_need
