Hi, I found a regression on current: The problem is meet with dd but I'm not sure it's the root cause. Here is how to reproduce the problem easily with 3 commands: dd if=/dev/zero of=/tmp/SOURCE.img seek=100000 count=0 mdconfig -a -t vnode -f /tmp/SOURCE.img dd conv=sparse if=/dev/md0 of=/tmp/DEST.img bs=64k => This last "dd" works great on 10.0-BETA3 and older but failed on -current (r258675 and r259096) with the message: dd: /dev/md0s1: Input/output error Regards, Olivier
