Basically I backup every weekend again from my 64-bits Ubuntu to my 32-bits FreeBSD. I solved the issue by setting the property dnodesize=legacy for the datasets I wanted to backup. I also reloaded those datasets once to get the storage with the right dnodesize everywhere.
The problem has been incompatibility of chosen dnode related settings of the datapool and dataset between Ubuntu and FreeBSD. With Openzfs rel 2.0, it might be easier, esp0ecially if both system can agree on using the same defaults. -- 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
