There's more trouble. I just copied several TB of data by zfs send | zfs recv from a 20.04 machine to this new machine. Worked well for hours, but at the end some crash messages, see attached second dmesg.
ZFS as it comes with 21.10 is definitely not production ready. ** Attachment added: "dmesg output of kernel problems" https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1947498/+attachment/5534455/+files/dmesg2 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1947498 Title: zfs/zpool encryption crash on server 21.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1947498/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
