@mafoelffen I'm sure the developers are hard at work with this and other issues.
Ubuntu LTS, I believe, does not yet have coreutils v9, so it is unlikely to be affected. This bug is actually extremely old (possibly going back almost two decades), but recent changes, such as a change to zfs_dmu_offset_next_sync and use of SEEK_HOLE in cp of coreutils increased the likelihood of this bug manifesting. According to recent comments by OpenZFS contributors, this bug actually seems unrelated to block cloning, though they are keeping it off by default to be safe (https://gist.github.com/rincebrain/e23b4a39aba3fadc04db18574d30dc73) in case there are other unknown bugs/interactions. So 2.2.1 is actually a false patch, and 2.2.2 is the real one, grounded in more evidence and investigation of the bug. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-hwe-6.5 in Ubuntu. https://bugs.launchpad.net/bugs/2044657 Title: zfs block cloning file system corruption Status in linux-hwe-6.2 package in Ubuntu: Confirmed Status in linux-hwe-6.5 package in Ubuntu: Confirmed Status in zfs-linux package in Ubuntu: Confirmed Bug description: OpenZFS 2.2 reportedly has a bug where block cloning might lead to file system corruption and data loss.
