Hey again :-) I'm starting to suspect that its a bug, since all I did was straight forward and it worked many times before.
When I try to stop the array by executing "mdadm -S /dev/md5", then mdadm stall (i'm suspecting it hit an error - maybe the same one). I also tryed to restart the computer and made sure the array didnt auto-start. I then manually started it and the reshape process it shown when executing "cat /proc/mdstat", but it doesnt proceed (it seems stalled right away). When I try to stop it as shown above, it then stall mdadm like before. So I'm able to reproduce the error. I've tryed with kernel 2.6.18.3, 2.6.18.4 and 2.6.19 - with the same results as described above. In case its a bug, then I would really like to help out, so its fixed and noone else will experience it (and I get my array fixed). What can I do to make sure its a bug and if it is, then what kind of information will be helpfull and where should I submit it? I've checked the source code (raid5.c), but there's no comment included in the code, so I cant do much myself since my code experience with C is very small when it comes to kernel programming.
