I am trying to install ZFS on Redhat 8.1 but sudo lsmod | grep zfs returns nothing, and when i run sudo modprobe zfs I get FATAL: Module zfs not found in directory /lib/modules/4.18.0-193.6.3.el8_2.x86_64

Here are my installation instructions

yum install http://download.zfsonlinux.org/epel/zfs-release.el8_1.noarch.rpm
yum-config-manager --disable zfs
yum-config-manager --enable zfs-kmod
yum install zfs
reboot

Looks like you are runing CentOS 8.2.2004 (wich was released yesterday).
Take a look at /etc/redhat-release on your system.

There are no kmod packages for 8.2 at this point.

I have tried on both Redhat 8.1 and CentOS 8.1, and it seems you are right, at some point the system is getting upgraded from 8.1 to 8.2

$ cat /etc/redhat-release 
CentOS Linux release 8.2.2004 (Core)

i opened #10466 for the issue of the missing packages for 8.2

Thats great!!! Right now a simple update of the system breaks everything. Thanks for your help.

Just wanted to get back and say thanks, 23 hours later, its working. My first issue was downloading driver 8.1 for 8.2, then installing 8.1 and updating to 8.2 as part of my initial server setup. doh!!!

Did you manage to update the kMod zfs driver from the 8.1 repo? Or are you using DKMS?

I couldn't update from 8.1 the kmod package as it's still compiled for 4.18.147. :(

On the ZFS page is particular instructions for upgrading, I am doing this on a fresh install. This is how I am doing this, note don't run yum update or dnf update as that will mess things up.

$ yum install yum-utils
$ yum install http://download.zfsonlinux.org/epel/zfs-release.el8_1.noarch.rpm
$ yum-config-manager --disable zfs
$ yum-config-manager --enable zfs-kmod
$ yum install zfs
$ reboot
