The lvm2 test suite aims at small test resource footprints (few PVs, small PV sizes) to run on tmpfs backed loop device. OTOH, lvconvert-reshape-raid.sh aims to test the maxima of supported total stripes of 64. This patch adds a prerequisite conditional to skip tests using more than 14 stripes. It requires the target version 1.13.1 to avoid deadlocks.
