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