Hm. This is dump of level 0, on a Monday morning,
when I rm the previous dumps and start anew
- could it be that the free space made by rm
only becomes available a _bit_ late due to softdep?
[ "x$l" = "x0" ] && rm -f $BKPDIR/dump$fsname.?
f=$BKPDIR/dump$fsname.$l
> $f && chown $BKPUSR:$BKPGRP $f && chmod 600 $f
dump -$l -a -u -f - $fs > $f 2> $BKPLOG
Because that happens, right? Create a few huge files
on a softdep FS, then remove them; the free space
only "appears a bit later".
I will try to add a sync in between the rm and the dump -0

No.
