I cant seem to find any reason for dump(8) to fail. Yet it does. We have a system that runs perfectly. However, when dumping (level 0) filesystems, we sometimes get strange errors with dump. A log of a failed dump follows at the end of this mail. We get no related kernel messages when this dump runs. These errors occur sometimes, and on different filesystems ( though appear only at /usr/ and /home; both larger partitions: Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/sd0a 49383 15619 31294 33% / /dev/sd1h 1572894 915801 578448 61% /home /dev/sd0e 99143 5406 88779 6% /tmp /dev/sd0f 847006 324963 479693 40% /usr /dev/sd0g 192547 77409 105511 42% /var /dev/sd0h 346863 127634 201885 39% /var/spool procfs 4 4 0 100% /proc /dev/sd2h 1928593 1655129 177034 90% /var/spool/news (news isn't dumped). I tried several dd's on these filesystems (dd if=... of=/dev/null bs=32k e.g.) and that all works okay. Further we don't see any strange behaviour on other programs whatsoever. -Guido DUMP: Date of this level 0 dump: Fri Mar 31 06:26:12 1995 DUMP: Date of last level 0 dump: the epoch DUMP: Dumping /dev/rsd1h (/home) to /dev/nDAT DUMP: mapping (Pass I) [regular files] DUMP: mapping (Pass II) [directories] DUMP: estimated 950618 tape blocks on 0.54 tape(s).
