** Description changed: 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 + This used to work before the recent Ubuntu kernel update from 5.8 to 5.11 + Kernel 5.8 came with zfs-kmod-0.8.4-1ubuntu11.2 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.
