  At least you'r lucky it's your test-server...

  Try a "show bfo 0 243145". If you'r lucky, this command shows something like:

  Storage Pool ID: xx  Volume ID: yy  Volume Name: 'volume_name'.
  If yes, you can try a "audit vol 'volume_name' fix=yes".

  If not, try a "auditdb". (How big is your database?).

  And if yes or no, always call your local Support immediatly, these errors
  are damn serious.

  Cheers,
