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?
