# Test activation behaviour with devices missing.
# - snapshots and their origins are only activated together; if one fails, both
#   fail
# - partial mirrors are not activated (but maybe they should? maybe we should
#   instead lvconvert --repair them?)
# - linear LVs with bits missing are not activated
