I can confirm problems relating to this ticket while transferring ZFS clones with zfs send and receive. This impacts on most Docker and LXD installations using ZFS.
Reproduced on: Operating System: Ubuntu 20.04.3 LTS Kernel (HWE): Linux 5.11.0-40-generic ZFS Packages: 0.8.3-1ubuntu12.13 ZFS Kernel Module: 2.0.2-1ubuntu5.4 The problem can be reproduced with the attached script (zfsbug_with_hwe.tar.gz). The error is sporadic so you have to start the script several times until the following occurs: "cannot receive: local origin for clone dummypool2/dataset1/clone2@snap3 does not exist" -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to zfs-linux in Ubuntu. https://bugs.launchpad.net/bugs/1939210 Title: When using HWE, zfs-kmod and zfs user tools versions must match Status in zfs-linux package in Ubuntu: Confirmed Bug description: Ubuntu 20.04.2 LTS I ran into a problem recently (https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1939177) due to mismatched versions when HWE upgraded the kernel from 5.8 to 5.11 where the userspace tools don't match the zfs-kmod version. After the update the system ended up with zfs-0.8.3-1ubuntu12.12 and zfs- kmod-2.0.2-1ubuntu5 My understanding from asking in the OpenZFS github is that the two versions must match. This bug is to figure out what to do for those of us who use HWE and zfs.
