I created a new test FS on the 8.2 machine with a single file in it and = it reproduces the problem. I did some tests with an md(4) backed zpool and it works on = 11.3-RELEASE-p5 and fails on 12.0-RELEASE-p10. Also, it appears I can 'launder' the send through the 11.3 machine, ie = recv on it then send to the 12.2 system and it works. Tested with the following: truncate -s 100M /tmp/zfs.1 sudo mdconfig -t vnode -f /tmp/zfs.1 sudo zpool create testtank /dev/md0 curl http://www.gsoft.com.au/~doconnor/test.zfssend.gz | gzip -d | sudo = zfs recv -vd testtank sudo zpool destroy testtank sudo mdconfig -u md0 -d rm /tmp/zfs.1 -- Daniel O'Connor "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum
