I will add an overview of the features of all involved datasets. The feature@userobj_accounting and feature@project_quota are not supported by FreeBSD 12.0 and are not part of feature list of FreeBSD as annexed, but they are active in Ubuntu. Why? I don't use them and don't intent to use them ever, so they should not be active but enabled. However I would not expect, that these features have any influence on the send/receive
feature@large_dnode is active in my FreeBSD pool, but according to your feature overview it is not supported by FreeBSD, so I assume that overview is not completely up-to-date. However I can send/receive with my archives datapool, like I said before. That archives datapool has the feature@large_dnode enabled but not active. So the incompatibility is in the feature@large_dnode. Unfortunately that is the default chosen by Ubuntu for rpool. So if the issue is not solved, I can never backup my 250 GB of virtual machines anymore, that are stored on rpool. Rsync is completely unusable for this type of incremental backup of 10-40 GB vdi files. I have seen that a new update of Ubuntu is available since a few hours, so I will update my system this evening. I also planned a week ago to upgrade FreeBSD 12.0 to the new 12.1. I hope that one of the two will solve my problem. I will inform you about the result. ** Attachment added: "zfs-bug3" https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1854982/+attachment/5309670/+files/zfs-bug3 -- 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
