As if last weekend's UEFI debacle wasn't bad enough, it now seems the latest C8 kernel (4.18.0-193.14.2) is incompatible with the current ZFSOnLinux packages (0.8.4-1). When booted to the latest kernel, ZFS is inaccessible on my C8 storage server. When I back off to the prior kernel (4.18.0-193.6.3), all is well.
If a local ZFS system is unavailable to the C8 kernel support folks, I'll be happy to assist them by volunteering my system as a lab rat.

CentOS doesn't have 'C8 kernel support folks' because CentOS does not offer support.
You would need to file a bug upstream with Red Hat, but I doubt they will be interested as they do not ship ZFS nor support it. I think you are likely on your own on this one.

please open an issue on zfsonlinux github: https://github.com/openzfs/zfs/issues and provide them a reproducible testcase.

Imho, that's out of CentOS scope, unless some people are willing to work on it with zfsonlinux people.

CentOS does not support, and will not support ZFS (unless it is rolled into RHEL).
Whatever packages you got for it .. they were written by ZFSOnLinux, not us. Ask them for an update.
