[lustre-discuss] Centos 7.7 upgrade

[Pascal Suter]

Hi

where you using the rpms from the whamcloud repo?

if so, check if you have installed the kmod-lustre-osd-zfs and 
lustre-osd-zfs-mount packages.

IIRC i had the same errors when the kmod-lustre-osd-zfs package was 
missing on my system.

cheers

Pascal
