Today, I run one round of the lvm2 tests with following script in my VM:
for t in `ls test/shell`; do
         if cat test/shell/$t | grep raid &> /dev/null; then
                 make check T=shell/$t
         fi
done

And the failed tests are:
[root@...ora lvm2]# cat log1 | grep "###   " | grep failed
###       failed: [ndev-vanilla] shell/lvconvert-raid-reshape-size.sh
###       failed: [ndev-vanilla] shell/lvconvert-repair-raid.sh

Then, I revert this set and test above tests again, they still fail. So
I didn't dig into these tests. :)

Thanks,
Kuai
