I've been testing both, Ubuntu Server and Debian in VM's to make a decision for installation for a production server.
One of the tests I ran was exactly this: Using mirroring for all of the system's partitions, including the OS.
I reproduced exactly the same steps for both OS's like 3 times each.
After each installation, I tried shutting down and removing one of the disks.
For Debian, succeeded all times. Reconnected the disk and resynchronized the disks and everything went OK.
For Ubuntu Server, failed all times, taking me to busy box shell. I could connect the disk back and boot it up without doing anything else.
Thought I've installed Ubuntu Server much more than 3 times before trying Debian out, I have further info about this behavior.
Twice, after reconnecting the disk back, I could see the disk resynchronizing, but at about 16% or so, I got kernel panic due to inability to synchronize disks in RAID1.
About the VM's:
Running latest VMware Server.
Ubuntu Server 7.10 - i386
Debian 40r3-i386
Hope it is of some use while pursuing a definite solution for this issue.
Best regards,
