In terms of a compact reproducer, does this work: # Create a temp pool with large_dnode enabled: truncate -s 1G lp1854982.img sudo zpool create -d -o feature@large_dnode=enabled lp1854982 $(pwd)/lp1854982.img
# Create a dataset with dnodesize=auto sudo zfs create -o dnodesize=auto lp1854982/ldn # Create a send stream sudo zfs snapshot lp1854982/ldn@snap sudo zfs send lp1854982/ldn@snap > lp1854982-ldn.zfs sudo zpool export lp1854982 cat lp1854982-ldn.zfs | ssh 192.168.1.100 zfs receive zroot/ldn If that doesn't reproduce the problem, adjust it until it does. You were using `zfs send -c`, so maybe that's it. You may need to enable more pool features, etc. But if this can be reproduced with an empty dataset on an empty pool, the send stream file is 8.5K (and far less compressed). Attach the script for reference and the send stream to a FreeBSD bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1854982 Title: Lost compatibilty for backup between Ubuntu 19.10 and FreeBSD 12.0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1854982/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
