Yes, but I also added an unbash_spaces(...) just a bit later in the same file. If you don't apply the second patch and have spaces in any of your Volume names to be restored, you will have similar problems. I recommend adding it too. > > askdir.c > > Remove "dcr->VolumeName[0] = 0;" from method "do_get_volume_info". > > I applied this to the version we are currently using (1.38.9), and tested. It > seems to have solved the problem! OK, many thanks for the feedback. It is nice to have it confirmed. As it turns out, I did make the failure of the SD to access the catalog only a warning message, but what I did not count on was that when the Dir reported no volume, the subroutine had zapped the Volume name, so that the restore then would not work. > > I think we can maintain this modification for the current time, and move up a > full version to 1.40 when available. > > Thanks for all that you do.
