program exited with error

with the fix.

the issue is

do cleanup and exit.
cleanup () {
local exit_status=$1
local host
case=${case:-"disk"}
shift
for ((i = 0; i < $ndevs; i++)); do
host=${host_names[$i]}
if [ -n ${do_teardown_ec[$i]} ]; then
^^^^ use single [] here will be true when do_teardown_ec does not exist
teardown_ec_devno $host ${client_names[$i]}
fi
done

will provide a patch soon
