Public bug reported: https://github.com/openzfs/zfs/issues/12462
Ubuntu 20.04.2 LTS Kernel: 5.11.0-25-generic #27~20.04.1-Ubuntu zfs-0.8.3-1ubuntu12.12 zfs-kmod-2.0.2-1ubuntu5 Trying to run zfs send | receive and getting an error: # zfs send 'rpool/home'@'autosnap_2020-08-01_00:59:01_monthly' | zfs receive -s -F 'nas/rpool_backup/home' cannot receive: failed to read from stream cannot receive new filesystem stream: dataset does not exist This used to work before the recent Ubuntu kernel update from 5.8 to 5.11 Ubuntu updates that broke it: Upgrade: linux-headers-generic-hwe-20.04:amd64 (5.8.0.63.71~20.04.45, 5.11.0.25.27~20.04.10), linux- image-generic-hwe-20.04:amd64 (5.8.0.63.71~20.04.45, 5.11.0.25.27~20.04.10), linux-generic-hwe-20.04 :amd64 (5.8.0.63.71~20.04.45, 5.11.0.25.27~20.04.10) Sending the zfs send part to a file works, but then sending the file to zfs receive also fails. The dump file size seems reasonable but the contents may not be correct. ** Affects: zfs-linux (Ubuntu) Importance: Undecided Status: New ** Tags: zfs zfs-kmod -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1939177 Title: Ubuntu 20.04.2 LTS kernel 5.11.0-25 zfs send | receive broken To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1939177/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
