Nick,

You can run "rpm -ql zfs" to get a list of all the files in that package to see where the zfs module was installed.

When I am trying to modprobe zfs this is the error I am getting
I have rebooted the server




[root at 1u user]# modprobe zfs


modprobe: FATAL: Module zfs not found in directory /lib/modules/4.18.0-425.3.1.el8_lustre.x86_64






FYI
[root at 1u user]# cd /lib/modules/4.18.0-425.3.1.el8_lustre.x86_64/extra/lustre-osd-zfs/fs
[root at 1u fs]# ls
osd_zfs.ko






Can you help with the error?
