Getting ZFS Working on Alpine Linux 3.18: Installing Packages and Modprobe
In this article, we will discuss the steps required to get ZFS up and running on Alpine Linux 3.18. We will cover the installation of the necessary packages, modprobe configuration, and creating a pool with datasets. By the end of this article, you will have a basic understanding of how to use ZFS on Alpine Linux 3.18.
Installing Packages
The first step in getting ZFS working on Alpine Linux 3.18 is to install the necessary packages. This can be done by running the following command:
# apk add zfs zfs-utils zfs-ltsp
This will install the ZFS kernel modules, userland tools, and the LTS kernel modules. Once the installation is complete, you can move on to configuring modprobe.
Modprobe Configuration
Before you can start using ZFS, you need to ensure that the ZFS kernel modules are loaded. This can be done by adding the following lines to the /etc/modules file:
# echo 'zfs' >> /etc/modules
# echo 'zpool' >> /etc/modules
Once you have added these lines, you can load the ZFS kernel modules by running the following command:
# modprobe zfs
You can verify that the ZFS kernel modules are loaded by running the following command:
# lsmod | grep zfs
If the ZFS kernel modules are loaded, you should see output similar to the following:
zfs 16777216 1
zunicode 1228800 1 zfs
zcommon 65536 1 zfs
znvpair 53248 2 zfs,zunicode
zavl 20480 1 zfs
zhash 32768 2 zfs,zunicode
zpool 503316 1 zfs
Creating a Pool and Datasets
Now that you have installed the necessary packages and configured modprobe, you can create a ZFS pool and datasets. In this example, we will create a pool named tank with two datasets:
# zpool create tank /dev/sda
# zfs create tank/data
# zfs create tank/home
You can verify that the pool and datasets have been created by running the following command:
# zpool list
NAME SIZE ALLOC FREE EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT
tank 931G 3.15G 928G - 0% 0% 1.00x ONLINE -
# zfs list
NAME USED AVAIL REFER MOUNTPOINT
tank 3.15G 928G 34.8K /tank
tank/data 34.8K 928G - /tank/data
tank/home 34.8K 928G - /tank/home
In this article, we have discussed the steps required to get ZFS working on Alpine Linux 3.18. We have covered the installation of the necessary packages, modprobe configuration, and creating a pool with datasets. With this knowledge, you should be able to get ZFS up and running on Alpine Linux 3.18.
