Actually, it may not be an issue even for Jammy HWE. My copy shows block cloning as an option that's off. -- 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/2044657 Title: Multiple data

This issue is different. It's another problem with block copy. But that's known to still be an issue. It's why block copy is disabled in 2.2.1. This is only an issue for the Jammy HWE, which has 2.2.0. No one should be shipping 2.2.0 with anything. It should be replaced with 2.2.1 at least. -- Yo

Since I was just referenced, note that I wouldn't favor putting 2.2 into Jammy. I would, however, prefer to see the latest 2.1.x. 2.2 is still seeing a substantial number of bug fixes. It will probably be ok by the release date of 24.04, but I still wouldn't change major versions for Jammy. -- Y

it's likely to take a while. It's been committed but not released. They chose to cherry pick the patch, so the version will still show as 2.1.5. A lot of us would prefer going to 2.1.14, but there are enough other changes that Ubuntu staff didn't want to do it. I'm considering building my own zfs m

For what it's worth, we've been running a file server for several weeks with the 2.1.14 .ko files in 22.04 with no problem. I didn't try to cherry pick the one fix as I'd prefer to have the whole 2.1.14. -- You received this bug notification because you are a member of Kernel Packages, which is s

Furthermore, slurm doesn't actually use the log data that the kernel would pass back. So my code is better even with kernels that work. Why pass a log buffer that you aren't going to use? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to lin

I'm concerned with the security implications of being frozen on a kernel we can't update. I suspect we should start testing an HWE kernel. That raises other issues, since there are lots of other features we also need to work, so it's going to require a fair amount of testing. I'd accelerate our mov
