Situation: i created software raid 1 configuration. Boot, swap and root on different partitions. After that i am trying to emulate haddrive problem. For this i am using virtualbox machine. I simply remove harddrive from system and trying to boot.

What expected: system boots normal.

What happened: First time after deletion system boots normal, but second time it drops into initramfs. I see that md devices exists in system and i can mount them. And array marked as degraded. When i return disk back system loads normal, but raid is checked as degraded and i need to add partitions to raid again. But if i don't do it system drops to initramfs again. So looks like system loads with degraded raid only if hardware configuration changed. Here few screenshots.

Screenshot when system stops booting:
