Description

copytool_setup() {
        local facet=${1:-$SINGLEAGT}
        local lustre_mntpnt=${2:-$MOUNT}
        local arc_id=$3
        local hsm_root=${4:-$(copytool_device $facet)}
        local agent=$(facet_active_host $facet)

        if [[ -z "$arc_id" ]] &&
                do_facet $facet "pkill -CONT -x $HSMTOOL_BASE"; then
                        echo "Wakeup copytool $facet on $agent"
                        return 0
        fi

        if $HSM_ARCHIVE_PURGE; then
                echo "Purging archive on $agent"
                do_facet $facet "rm -rf $hsm_root/*"
        fi

If the $hsm_root variable is not defined, rm -rf /* command will be executed.

Easy way to reproduce (please, be careful!!! files on mounted shares will be deleted as well as on cluster node!)
