Bug#865976: mdadm destroys my LSI Megaraid software raid

[Christoph Pleger]

Package: mdadm
Version: 3.3.2-5+deb8u2
Severity: critical

Dear maintainers,

I created a virtual drive in the the RAID-Setup of a computer with LSI 
Megaraid software raid support. Then I booted from my self-created 
installation DVD (that has mdadm installed), let it partition the 
virtual drive and installed a basic system on the drive. But at the next 
boot, when I wanted to start from the basic system on the drive, that 
was not possible because the virtual raid drive had disappeared, that 
means the drive was neither shown in the boot order list, nor in the 
RAID setup routine of the computer.

My temporary solution was to switch back to dmraid, which handled my 
RAID setup without destroying it.

Regards
   Christoph
