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

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
