Which distro are you running specifically?
zfs-2.1.15 builds on AlmaLinux 9.4 with the latest 5.14.0-427.16.1.el9_4.x86_64 kernel:

Distro: Centos Stream 9, with Centos-Stream 9 kernel-5.14.0-444.el9.x86_64 compile is fine.
Counter point. CentOS Stream is previewing the upcoming changes to RHEL, AlmaLinux, and RockyLinux. Those distros will soon pick up this backported kernel version 6.9 change (which I know 6.9 isn't fully supported yet either). I've tracked down this particular code change to this commit. https://github.com/torvalds/linux/commit/e97d06a46526d9392cbdbd7eda193091e1af2723 If there's a "Support kernel version 6.9" issue somewhere, I think we could mark this a duplicate of that ticket.
Additionally, downgrading to kernel 5.14.0-444.el9.x86_64 will work for CentOS Stream 9 users. So it's only this brand new 446 kernel package that has new code.
Maybe someone is interested for Centos 9 you can easily assemble zfs-2.2.4 from srpm fedora 40, with kernel 446 everything seems to work.
@smusich you should also be able to install the EL9 dkms packages as well. That should alleviate the issues when the RHEL/Alma/Rocky/Stream kernel version numbers are not 100% matched up.
@smusich I simply used the Fedora 38 repo. Works without any further changes. Just needed to hardcode the fedora release version.
@tonyhutter I believe we are both already on zfs-dkms via epel/zfs-release-2-3.el9 as instructed in the current "Getting Started" section.
Btw. since I was not aware that Centos-Stream was not supported, that might be sth. to clarify on that Getting Started page. Since Stream has existed for a while and the non-Stream variants had been discontinued, I simply counted "CentOS-Stream" as covered under "CentOS-based distros".
@ramonwirsch I use Fedora 40 repo. I'm currently running a test from the package zfs-test.
You can cherry-pick these commits and it seems to build again (they cherry-pick cleanly)
https://github.com/openzfs/zfs/commit/cfb96c772b8448dca6eaeb66a540b8bb39c9908c https://github.com/openzfs/zfs/commit/e3120f73d0481a5e0779e45da83518373d60dcff
What goes inte CentOS Stream usually ends up in the next RHEL release. On RHEL 9.5 beta (currently kernel-5.14.0-503.2.1.el9_5.x86_64), zfs-2.1.15 does build with the two cherry-picks suggested above.
Are there still plans to release zfs-2.1.16? If so, will it be supported on RHEL 9.5?
Using zfs-testing worked for me. Current kernel - 5.14.0-522.el9.x86_64
dnf install https://zfsonlinux.org/epel/zfs-release-2-3$(rpm --eval "%{dist}").noarch.rpm
dnf install -y epel-release
dnf config-manager --enable zfs-testing
dnf install kernel-devel zfs
This will install zfs-2.2.6 instead of zfs-2.1.15. Will compile kernel modules and zfs-dkms. Manual build from source zfs-2.2.6 also works.
Don't forget to rebuild initrd:
dracut --regenerate-all -f
AlmaLinux 9.5 has been released with kernel 5.14.0-503.11.1.el9_5.x86_64 and compiling zfs 2.1.15 sources fails with
checking whether bdev_open_by_path() exists... configure: error:
*** None of the expected "blkdev_get_by_path()" interfaces were detected.
Will there be an official 2.1.16 release?
If not, is it safe and sufficient to apply patches cfb96c7 and e3120f7? I've successfully built a custom 2.1.16pre RPM including those patches, but I don't know if this may cause issues on production servers later on.
