I found some discussion on the Internet https://discuss.linuxcontainers.org/t/lxd-5-12-zfs-stopped-working-in- lxd-error-required-tool-zpool-is-missing-when-kernel-zfs-module- version-0-8/16753/17
It looks like it's the 5.0 stable lxd on Jammy is too old for this $ sudo snap list Name Version Rev Tracking Publisher Notes core20 20230801 2015 latest/stable canonical✓ base lxd 5.0.2-838e1b2 24322 5.0/stable/… canonical✓ - snapd 2.60.3 20092 latest/stable canonical✓ snapd If I remove lxd and install it again, this will work. So I think we can fix our test case with: sudo snap refresh lxd --channel=latest -- You received this bug notification because you are a member of Canonical Platform QA Team, which is subscribed to ubuntu-kernel-tests. https://bugs.launchpad.net/bugs/2036861 Title: shiftfs-lxd.sh test in ubuntu_overlayfs_smoke_test failed with J-oem-6.5 Status in ubuntu-kernel-tests: New Bug description: This was failing due to the lack of ZFS support (LP: #2031269). With ZFS support added to the kernel in 6.5.0-1004 this is still failing: Running 'sudo -iu ubuntu /home/ubuntu/autotest/client/tmp/ubuntu_overlayfs_smoke_test/src/overlay-shiftfs-tests/tests/shiftfs-lxd.sh' Error: Required tool 'zpool' is missing Creating c1 Error: Failed loading storage pool "zfs": Storage pool not found Error: Instance not found FAIL Error: Instance not found Error: Failed checking instance exists "local:c1": Instance not found Error: Storage pool not found We have also fixed the lxd update issue https://git.launchpad.net/~canonical-kernel-team/+git/overlay-shiftfs- tests/commit/?id=13d28992b5513c984c7c8b1467e6bd8d66ee5c93 And the zpool command exists.
