After postponing an upgrade from 7.2 to 8.0 for some time, I now am attempting to make the transition. In the 7.2 install, I have one "dangerously dedicated" disk used only for backup (the accommodation of which is why I postponed the install in the first place), as well as a boot disk that was set up using slices. In addition, I have an external USB mass storage device that I have placed level 0 dumps of all filesystems upon. When I install 8.0 to a fresh disk (which is then set up using sysinstall), I can boot off the fresh disk and see all of the just-installed files perfectly. Here is the puzzler: if I boot 8.0, and mount any filesystem that was created by 7.2 or earlier, I cannot see any files. This includes both the non-DD internal disk (which is the boot disk for 7.2), as well as the external USB mass storage (formatted using UFS, but also not a DD setup). To add to the puzzle, df reports a usage number that reflects the block allocation, but ls does not report any filesystem entries. My primary objective is to make the dump files available under 8.0, so I tried booting 7.2 again, mounting my new (empty) /home partition and placing the files there -- this seemed to work as seen under 7.2, however when I rebooted using 8.0, there are again no files visible in this partition. Does anyone have any ideas on: (a) what the underlying problem could be (noting that although I have a DD disk, it is not involved in this process in any way) -- especially given that it seems to affect the filesystems on the external drive, or (b) what a path might be to getting the dump files to the new system so that I can use it? (I should mention that the dumps are rather huge (~100Gb), so a network based solution is rather unpalatable). Any input appreciated, Andrew.
