Description

start() requires 2nd parameter device. If start() is called without the 2nd parameter - the
empty mds1_dev is exported:

start() {
        local facet=$1
        shift
        local device=$1
..
        eval export ${dev_alias}_dev=${device}

and test fails on failover setup with:
CMD: lm0301 loop_dev=$(losetup -j | cut -d : -f 1);
lm0301: losetup: option requires an argument – 'j'

dm_create_dev()
  local real_dev=<empty>
        -> setup_loop_device $facet <empty>

To reproduce the failure just run:
ONLY=160p sh sanity.sh
on failover setup where mds1_HOST != mds1failover_HOST.
