title: AWS RDS storage-full
body: <p>For some reason, mysql instance on RDS was storage-full, I tried to truncating one of the table used for logging, there were about 9 million data source in this tables, unfortunately, this sql sentence "truncate tableA;" already run over 60 hours! it was still running and this table seemed to be locked, because when I checked the count of this table, it stuck, is there any other way to leave some spaces for mysql, shall me wait until this truncate sentence completed?</p>
  
  <p>thanks in advance.</p>
