hi, I'm testing the new CentOS 8, seems latest kmod-kvdo-6.2.0.293-50.el8.x86_64 does not contain modules for latest kernel kernel-4.18.0-80.7.1.el8_0.x86_64
The kmod can be built against an older kernel and used on the more modern version. That is, unless the symbols in use had a signature change, which would signal to the kernel module that they may not work with the newer kernel.
rpm -ql kmod-kvdo-6.2.0.293-50.el8.x86_64 /etc/depmod.d/kvdo.conf /lib/modules/4.18.0-79.el8+2.x86_64 /lib/modules/4.18.0-79.el8+2.x86_64/extra /lib/modules/4.18.0-79.el8+2.x86_64/extra/kmod-kvdo /lib/modules/4.18.0-79.el8+2.x86_64/extra/kmod-kvdo/uds /lib/modules/4.18.0-79.el8+2.x86_64/extra/kmod-kvdo/uds/uds.ko /lib/modules/4.18.0-79.el8+2.x86_64/extra/kmod-kvdo/vdo /lib/modules/4.18.0-79.el8+2.x86_64/extra/kmod-kvdo/vdo/kvdo.ko /usr/lib/.build-id /usr/lib/.build-id/4d /usr/lib/.build-id/4d/fae93dd1945f44167de4f5e60bc6dcac0aed54 /usr/lib/.build-id/af /usr/lib/.build-id/af/e99d52bb67273e1bca049b950ea37044005aa8 /usr/share/doc/kmod-kvdo/greylist.txt
This should be fine, I see the two kernel modules in the list.
it is clean install without external repo. I'm missing something ?
Can you run as root (or with sudo) `modprobe kvdo`?
Thanks, Andy
