X-Mailer: NeoMail 1.2.1 X-IPAddress: 209.202.83.2 MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1 Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG I tried to do another zero level dump this evening, on a tape which I had previously used for a zero level dump. It dumped about 1.8gigs, and then asked for the second tape volume; the drive is a DDS-2 (4gig/8compressed) internal Seagate SCSI DAT. I used the command: dump -0au /server; when I do a df, the partition /server has only got about 2.1gigs used (out of a possible 4.3 on a RAID array (mirrored via hardware controller), so I know it shouldn't be a capacioty issue). What I'm not sure of though, does dump over-write what's on a tape, or append to it? If the latter is true this would make sense; but if not then how exactly to I force dump to either overwrite with a new volume on the tape each time, or erase the tape beforehand? I also thought, that maybe since I've forced dump to auto-detect the capacity of the tape that it a_may not be compressing the data to achieve the 8gig capacity of the drive, or b-may be somehow screwing up, or as previously assumed appending to an existing volume. Any thoughts, ideas, or further locations for which to seek some insight would be greatly appreciated. I will try again this evening (this time with a brand-new unused tape), to see if the same happens. Seeing as how approx three weeks before this attempt the origional worked; I am assuming that it's not a capacity issue. -- Nathan Vidican Nathan@Vidican.com http://Nat To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
