- I made a level 0 dump of my 2.1 system before the 3.0 installation. I can
- restore -i and cd and ls all around the tape, so I know that restore can
- read the table of contents. I can add files to the extract list without
- complaints but restore seems to get confused when I say extract.
-
- % mtset -v -i
- setting tape device (/dev/nrst0) to variable block size mode with illegal
- length reporting inhibited
- % mtinill
- % mt -f /dev/nrst0 rewind
- % /usr/etc/restore if /dev/nrst0

- You have not read any tapes yet.
- Unless you know which volume your file(s) are on you should start

- Here is the unsuccessful result that I get after running mtinill:
-
- % mtinill
- % mt -f /dev/nrst0 rewind
- % /usr/etc/restore xf /dev/nrst0
- ./NextLibrary/Literature/Shakespeare/.dir.tiff

- PS. I'm NOT really trying to get that tiff, it's just an example!
