Bug#519760: Also, is it safe to mount rw during search phase?

["Bobi B." <606u@dir.bg>]

One more thought: is it safe to mount individual partitions from a RAID1 
array for read-write? Could this make RAID1 array to go out of sync? I'm 
not sure in what I'm saying, but if unmount modifies file system's 
meta-info (like unmount time stamp) both partitions from the array could 
become different, effectively damaging the array.
