kernel-ml suppoert

[slavonnet]

I not understand .... zfs can compile and work on 5.13 ....

https://elrepo.org/bugs/view.php?id=1111

What do they have to introduce?

[rincebrain]

If I'm reading it correctly, they're not willing to provide binary kernel module packages of anything out of tree because they'd need to rebuild them every kernel update, since kernel-ml doesn't provide the same guarantees as vanilla RHEL kernels that they can keep using a driver built against an older one in the same release.

It's not OpenZFS-specific, and I don't think it's something OpenZFS can fix. (OpenZFS could, in theory, cut its own kernel-ml kmod packages, but I would strongly doubt that they would, because they don't provide kmod packages for Fedora for the same reason.)

Has something happened with kernel-ml DKMS as well:

 dkms --force install zfs/2.1.5

Kernel preparation unnecessary for this kernel.  Skipping...

hmm, or it's still 5.19 support missing instead?

grep -Hnr "CONFIG_MODULES="  /usr/src/kernels/5.19.1-1.el7.elrepo.x86_64/
/usr/src/kernels/5.19.1-1.el7.elrepo.x86_64/.config:850:CONFIG_MODULES=y

It seems so. This machine is just trying to downgrade ZFS to FUSE, while the kernel upgrades to 5.19:

$ dnf upgrade | grep -B 1 'zfs|kernel'

Kernels at 5.19 will become available with the 2.1.6 release. This commit can be found in the 2.1.6-staging branch:

57e1052

It will allow for Linux 5.19 build hosts:

zfs/META

Line 9 in 57e1052

Linux-Maximum: 5.19
