Hi, this is a known issue with Linux 6.11 and zfs 2.2.6. Even if it's considered harmless you should really backport this until 2.2.7 gets released: https://github.com/openzfs/zfs/pull/16539
You can't use the diff from that PR since it won't apply cleanly, but it's easy enough to backport and you reuse my patch from zfs-dkms- staging-git: https://aur.archlinux.org/cgit/aur.git/commit/?h=zfs-dkms- staging-git&id=c0037ba49d9739c753506640a91a716032d6f943 The patch is called "linux610-zfs_log-add-flex-array-fields-to-log- record-structs.patch" and we use it since a couple of weeks without issues. You can also find it here where I constantly rebase on top of the latest staging branch: https://github.com/darkbasic/zfs/commits/zfs-2.2.7-staging-backports/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2082060 Title: memcpy: detected field-spanning write (size 8) of single field "lr + 1" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/2082060/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
