Description of problem:
This was the 10th iteration of this test so this certainly doesn't happen every time.

./mirror_sanity -l /home/msp/cmarthal/work/rhel5/sts-root -r /usr/tests/sts-rhel5.5 -R ../../var/share/resource_files/taft.xml -e segmented_pvmove

SCENARIO - [segmented_pvmove]
Create a couple small segmented lvs and then pvmove them
Running lv_seg on taft-02 to create the segmented volumes
taft-02: /usr/tests/sts-rhel5.5/lvm2/bin/lv_seg -v mirror_sanity -n segment
Deactivating segment0 mirror
Moving data from pv /dev/sdc1
taft-02: pvmove -v /dev/sdc1
    Finding volume group "mirror_sanity"
    Executing: /sbin/modprobe dm-log-clustered 
    Archiving volume group "mirror_sanity" metadata (seqno 53).
    Creating logical volume pvmove0
    Moving 273 extents of logical volume mirror_sanity/segment0
    Moving 219 extents of logical volume mirror_sanity/segment1
