I have an DIY Ubuntu NAS (one of the first few linux installs), and I was having aggravations with the zfs-dkms package that I had setup a couple of years ago to host raided pools for my NAS setup. 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.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
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.
|
||||
</p>
|
||||
|
||||
<pre 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="$(</etc/depmod.d/ubuntu.conf)"
|
||||
## Replace "search" with "search extra" to put the extra modules into the depmod path
|
||||
depmod_cont="${depmod_cont/search/search extra}"
|
||||
echo "$depmod_cont" > /etc/depmod.d/ubuntu.conf
|
||||
|
||||
## Build and intall
|
||||
make install
|
||||
</pre>

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 <code>zpool import data && zpool import media</code>
|
||||
</p>
|
||||
|
||||
<p>
|
||||
I was confused because the configs setup by my dkms installation were still valid <code>/etc/defaults/zfs</code>.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
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.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
the services configured in /usr/lib/systemd/system were setup with the path that bsd/unix would use for the zpool.cache file (<code>/usr/local/etc/zfs/zpool.cache</code>) instead of what zfs was configured with on my zfs-dkms installation (<code>/etc/zfs/zpool.cache</code>).

||||

<p>
|
||||
All I ended up needing to do was change the path's that the service files from <code>/usr/local/etc/zfs/zpool.cache</code> to <code>/etc/zfs/zpool.cache</code> (wherever applicable).
|
||||
</p>
|
||||
|
||||
<p>
|
||||
After doing that and rebooting the pools were imported and mounted as they previously had.
