  /test:
        dev             = /dev/test_lv
        vfs             = jfs
        log             = /dev/loglv01
        mount           = true
        account         = false
        options         = rw,nointegrity

mount /test and enjoy faster rw-speed (BUT, take the risk of permanent data loss...)
