Reply-to: peirce%pernod@gumby.cc.wmich.edu (Leonard J. Peirce) Well, I just installed 3.0 and discovered that either DEC didn't fix the bug that I reported or they didn't understand what I was trying to explain to them. Maybe I'm dumb for doing this; you be the judge. I do our dumps using multiple dump files on mutilple tapes. A breakdown of the dump file and tape boundaries is such: |------------tape 1------------||------------tape 2------------||------- |---dump 1---||---dump 2---||---dump 3---||---dump 4---||---dump 5---||--- The problem shows up when I run restore. restore can find anything in the dump files 1 and 2. However, if I try to get to anything in dump file 3 and up, I get the message Wrong dump date got: Tue Dec 27 11:18:14 1988 wanted: Wed Dec 31 19:00:00 1969 shortly after I insert the second tape. If I force a new tape to be inserted such that any dump file that will require more than one tape starts at the beginning of the tape, restore works fine for everything. Should dump/restore be able to handle the situation I described above? I've got my asbestos thermal underwear on so if I'm being stupid, you can flame me if you want; do it by e-mail, though, so as not to waste everyone's bandwidth. Anything constuctive should be posted. -- Leonard J.

Reply-to: peirce@gumby.cc.wmich.edu (Leonard J. Peirce) Well, I just installed 3.0 and discovered that either DEC didn't fix the bug I reported or didn't understand what I was talking about. Maybe I'm dumb for doing this; you be the judge. The problem is this: I do our dumps using multiple dump files on multiple tapes, with some dump files crossing tape boundaries. A breakdown of the tape and dump file boundaries would be: |------------------tape 1------------------||---------tape 2---------||------ |---dump file 1---||---dump file 2---||---dump file 3---||---dump file 4---| Dump doesn't complain about anything, asking for new tapes when it thinks it needs one. The problem shows up when I run restore. It can get to anything in dump files 1 and 2, but if I try to get to anything in dump file 3 or beyond, I get the message Wrong dump date got: Tue Dec 27 11:18:14 1988 wanted: Wed Dec 31 19:00:00 1969 soon after I insert the second tape. restore works just fine if I force a new tape to be inserted such that if a dump file will require more than one tape, it starts at the beginning of a tape. Am I dumb for using dump the way I described above? I've got my asbestos thermal underwear on so you can flame me for being stupid if you feel like it; just send them directly to me. Anything constructive can be posted. -- Leonard J.

Stick (well insert) tape 2 in the drive on put it online. Then run the restore command "skipping" to the second dump on the tape. For example: restore -ivfs /dev/rmt0h 2 the "s 2" combo will skip to the second dump on the tape. "dump 3", the partial dump is considered "dump 1". > Should dump/restore be able to handle the situation I described above? > I've got my asbestos thermal underwear on so if I'm being stupid, you > can flame me if you want; do it by e-mail, though, so as not to waste > everyone's bandwidth. Anything constuctive should be posted. No flame needed. DEC Ultrix support couldn't help me on this one either. I finally figured it out myself. Good Luck.
