I'm not sure if userobj_accounting and/or project_quota have implications for send stream compatibility, but my hunch is that they do not. large_dnode is documented as being an issue, but since your receiver supports that, that's not it.
I'm not sure what the issue is, nor what a good next step would be. You might ask on IRC (#zfsonlinux on FreeNode) or the zfs-discuss mailing list. See: https://github.com/zfsonlinux/zfs/wiki/Mailing-Lists Not that it helps now, but this will get somewhat better in the future, as FreeBSD is switching to using the current ZFS-on-Linux, which will be renamed to OpenZFS, codebase as its upstream. So Linux and FreeBSD will have feature parity, outside of the usual time lag of release cycles. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to zfs-linux in Ubuntu. https://bugs.launchpad.net/bugs/1854982 Title: Lost compatibilty for backup between Ubuntu 19.10 and FreeBSD 12.0 Status in zfs-linux package in Ubuntu: New Bug description: After I tried to back-up my datapools from Ubuntu 19.10 to FreeBSD 12.0 as I have done since June each week, I found out it did not work anymore. The regression occurred after I reinstalled Ubuntu on my new nvme drive. I also had to reorganize my own datapools/datasets, because they either moved to the nvme drive or they had to be located on 2 HDDs instead of 3. I had one datapool that still works, the datapool containing my archives and it is the datapool, that has NOT been reorganized. I tried for a whole long day to get the backup working again, but I failed. I compared the properties from datapool and dataset, but did not see any problem there. Only a lot of new features and properties not present before and not present in FreeBSD. I used FreeBSD, because I use for backup an old 32-bits Pentium. I have two complaints: - the Ubuntu upgrade did cost me the compatibility with FreeBSD. Open-ZFS? :( - the system transfers the dataset and at the end of a long transfer it decides to quit and the error messages are completely useless and self contradicting. On the first try it say the dataset does exist and on the second try it says it does NOT exist. One of the two is completely wrong. Some consistency and some clearer error messages would be helpful for the user. See the following set of strange set error messages on two tries: root@VM-Host-Ryzen:/home/bertadmin# /sbin/zfs send -c dpool/dummy@191130 | ssh 192.168.1.100 zfs receive zroot/hp-data/dummy cannot receive new filesystem stream: destination 'zroot/hp-data/dummy' exists must specify -F to overwrite it root@VM-Host-Ryzen:/home/bertadmin# /sbin/zfs send -c dpool/dummy@191130 | ssh 192.168.1.100 zfs receive -F zroot/hp-data/dummy cannot receive new filesystem stream: dataset does not exist A 2nd subset of my backup is stored on the laptop and that still works. I also compared the properties with those of my laptop, that still has its original datapools of begin of the year. I aligned the properties of FreeBSD with those of my laptop, but it did not help. I attach the properties of the datapool and dataset from both FreeBSD and Ubuntu.
