[linux-lvm] merge two lvms on same VG

[tariq wali]

thanks for the reply , but wouldn't that merge LV's from two different
volume groups and for some weird requirement I wanted to merge LV's from
the same VG , say

merge /dev/vg0/data and /dev/vg0/data1 into a  merged volume without any
data loss .
