Hi, guys:
I found that when disk errors happened, it is more likely to locate in
md super block area. Kernel messages are like this:
end_request: I/O error, dev sda, sector 1953525000
md: super_written gets error=-5, uptodate=0
In some cases, I check if disk is really failed using 'dd' command and
found that it is OK for read and write on those sectors.

I know that md super block information is located in the end of a
disk, but is it related with this problem? Is it safer to put md super
block in the start area of a disk?
