Advice how to prevent data loss on JFS

  • Please, don't use JFS filesystem with old harddisks. New bad sectors may cause loss of data;
  • Use UPS to protect against power leaps;
  • Don't fill JFS volume completely. Always keep freespace (10% of total volume size);

If you don't follow this simple instructions then purchase JUne - utility to rescue/undelete data from JFS volumes.
