Hi Neil, only to be sure to have understood everything correctly: Suggestion is to create for example one root partition and a swap partion. And I will create on big "rest of the disk"-partition. The last one will be subdivided with LVM into portions as needed. Since the last big partition is big due to physical reasons (not for logical one): What will happen, if -- for example -- one portion will be not unmounted cleanly and while booting/checking fails to recover? Are all others damaged/lost? Best regards, mcc -- Please don't send me any Word- or Powerpoint-Attachments unless it's absolutely neccessary. - Send simply Text.
