zfs Module Notes

There are a few considerations to be aware of when enabling the zfs module

• You must provide zfs kernel modules or kernel support on the ISO for the zfs module to function
  • The zfs kernel module must be loaded prior to the partition module running
  • One way to achieve this is by running modprobe zfs
• Support for zfs in the partition module is conditional on the zfs module being enabled
• The config for the default pools and datasets is configured and described in modules/zfs.conf
• If you use grub with zfs, you must have ZPOOL_VDEV_NAME_PATH=1 in your environment when running grub-install or grub-mkconfig.
  • Calamares will ensure this happens during the bootloader module.
  • It will also add it to /etc/environment so it will be available in the installation
  • If you have an scripts or other processes that trigger grub-mkconfig during the install process, be sure to add that to the environment
• In most cases, you will need to enable services for zfs support appropriate to your distro. For example, when testing on Arch the following services were enabled:
  • zfs.target
  • zfs-import-cache
  • zfs-mount
  • zfs-import.target
