Hi there,

two days ago I was trying to grow my existing md raid5 array (with mdadm 
2.6.3 old version in ubuntu hardy). Everything goes well, but after one 
day in process of reshaping got power outage and must restart the 
reshaping process. I learned from some forums, that mdadm 2.6.3 have bug 
for restoring this process, and it's fixed in 2.6.4. So I download and 
make 2.6.4. With this version everything goes well, and reshaping 
process start again.

And now my problem: I do recent upgrade to new Ubuntu release (8.1) and 
system upgraded the mdadm package to 2.6.7. The version 2.6.7 gave me 
segmentation fault when I try to restore reshaping process.
I'm attaching strace of both 2.6.4 and 2.6.7.

oryon@server:~$ uname -a
Linux server 2.6.24-19-server #1 SMP Wed Aug 20 23:54:28 UTC 2008 i686 
GNU/Linux
oryon@server:~$ mdadm --version
mdadm - v2.6.7 - 6th June 2008
oryon@server:~$ /home/oryon/mdadm-2.6.4/mdadm --version
mdadm - v2.6.4 - 19th October 2007

I think the problem is only in 2.6.7. If it's needed, I can try this 
also in 2.6.5 or 2.6.6.

Best,

Vladislav
