I updated both Ubuntu and I upgrade FreeBSD to 12.1, but it did not help. Both system remain incompatible.
So what should we learn: - Never break the send/receive compatibility, especially not if you demand during the install the complete disk (Ubuntu) or all complete disks (Raid-0 or 1) (FreeBSD). The minimum improvement I expect for the 20.04 installation, is one size parameter! So that I can limit the part of the disk used by Ubuntu itself (ext4 partition + swap partition + bpool + rpool). For Ubuntu it is like installing on a smaller disk. At least the remainder of the disk could be used to create own datapools with the correct feature settings. - ZFS should give useful not conflicting error messages as explained in my first entry. In the mean time I have to; - backup my dpool (normal files) on my HDDs an recreate dpool with the correct feature set; - restore those normal files to dpool and run the send/receive backup to FreeBSD; - copy my VMs temporarily to that new dpool and delete those datasets on rpool. - snapshot all Ubuntu datasets and send/receive those to an USB drive. - boot from ext4, I'm lucky I have a dual boot with ext4 and zfs. - delete rpool, create a new 20GB rpool version and reverse send/receive Ubuntu from USB to rpool - check UUIDs in /boot/grub/grub.cfg, fstab and resume; reboot and pray - recreate a vpool for the virtual machines with the right feature set and restore those. - run the backup to FreeBSD. My laptop has already large-dnode active as result of an incremental backup, so I have to recreate that datapool too with the right feature set. As last resort I take my last free SATA HDD (80GB) from my 2nd desktop and install Ubuntu on it and use the 512GB NVME SSD for my virtual machines. That Ubuntu Host OS is a minimal install and I only use Firefox, nautilus, the terminal and gedit from it. In practice the Host OS will run completely from L1ARC, surely if I use Firefox from the VMs like I do often. -- 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
