However, recently during an update I noticed the kernel was updated on the machine to 6.2.0-39-generic which now caused the zfs-dkms to throw errors when apt would run mkinitcpio as the zfs-dkms-2.1.5 module only supported up to kernel 5.19. While it didn't exactly cause any issues with the zfs installation there was currently (it still functioned fine even with the new kernel). I got tired of it so I decided to compile openzfs from source and install it on my system. {{{bash sudo -i git clone https://github.com/openzfs/zfs ## I was missing a few dependencies but installed them like so apt install uuid-dev libblkid-dev cd zfs ## Run the autoconf autogen script ./autogen.sh ## Run the configure script to build the Makefile ./configure ## Build the module to make sure everything goes ok make ## Had to add the extra modules to the depmod search ath depmod_cont="$( /etc/depmod.d/ubuntu.conf ## Build and intall make install }}} == Other issues == === Zpools not importing === ---------------------------- Upon finishing installation and reboot I noticed that when the server rebooted it didn't mount the pools on boot. I always had to import them manually `zpool import data && zpool import media` I was confused because the configs setup by my dkms installation were still valid `/etc/defaults/zfs`. While it took me an hour to figure it out, I eventually figured out what was wrong and why zfs wasn't importing my pools. the services configured in /usr/lib/systemd/system were setup with the path that bsd/unix would use for the zpool.cache file (`/usr/local/etc/zfs/zpool.cache`) instead of what zfs was configured with on my zfs-dkms installation (`/etc/zfs/zpool.cache`). === Resolution === ------------------ All I ended up needing to do was change the path's that the service files from `/usr/local/etc/zfs/zpool.cache` to `/etc/zfs/zpool.cache` (wherever applicable). After doing that and rebooting the pools were imported and mounted as they previously had.
