Do you still have the dump files so you can see if the problem is in dump or restore? Did you do something strange like make one of the file systems something other than UFS? > On a side note, why is dump/restore so dead slow?

I don't think speed was a critical factor when they were written, as most dumps went to open reel tapes, which are *slow*. I recall lots of hacks/patches/workarounds to make dump output to streaming tape drives actually stream. > (*) What are they called on BSD? Protectionsbit, modes or flags? Modes. They are bits, but modes is more specific. Flags are different things; see the chflags man page for more information. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
