** Description changed:

+ Reproducing:
+ 
+ 1. Install Ubuntu 12.04 with md raid.
+ 
+ My system has:
+ 
+ $ cat /proc/mdstat 
+ Personalities : [raid1] [linear] [multipath] [raid0] [raid6] [raid5] [raid4] 
[raid10] 
+ md1 : active raid1 sdb2[1] sda2[0]
+       522048 blocks [2/2] [UU]
+       
+ md0 : active raid1 sdb1[1] sda1[0]
+       10490304 blocks [2/2] [UU]
+       
+ md2 : active raid1 sdc1[0] sdd1[1]
+       805305143 blocks super 1.2 [2/2] [UU]
+       
+ unused devices: <none>
+ 
+ 2. Try running this mdadm command, observe unexpected results:
+ 
+ # mdadm --monitor --scan --oneshot
+ mdadm: Only one autorebuild process allowed in scan mode, aborting
+ 
+ 3. Also cron will send mail:
+ 
  /etc/cron.daily/mdadm:
  mdadm: Only one autorebuild process allowed in scan mode, aborting
  run-parts: /etc/cron.daily/mdadm exited with return code 1
  
- fixed in Debian, please merge from them.
+ 4. Stop any mdadm processes (but only for testing, it is unacceptable to
+ turn off mdadm monitoring.)
+ 
+ # service mdadm stop
+ 
+ 5. Try running, observe expected results:
+ # mdadm --monitor --scan --oneshot
+ (no output)
+ 
+ This issue was fixed in Debian, please d-i this version:
+ 
+ Format: 1.8
