This is the second time I step into this crap. Let’s save some handy commands for the future. After updating the distribution of my Ubuntu Server box, the ZFS kernel module is missing. I get the following error during the upgrade:
configure: error: *** Please make sure the kmod spl devel <kernel> package for your *** distribution is installed then try again. If that fails you *** can specify the location of the spl objects with the *** '--with-spl-obj=PATH' option.
I’m not sure what exactly helped, but installing all updates, rebooting and reinstalling zfs-dkms finally solved the problem:
sudo apt-get update sudo apt-get upgrade sudo apt-get install --reinstall zfs-dkms
