This package adds a zfs dracut module +to the /usr/share/dracut/modules.d/ directory which allows dracut to +create an initramfs which is zfs aware. + +2) Set the bootfs property for the bootable dataset in the pool. Then set +the dataset mountpoint property to '/'. + + $ zpool set bootfs=pool/dataset + $ zfs set mountpoint=/ pool/dataset + +Alternately, legacy mountpoints can be used by setting the 'root=' option +on the kernel line of your grub.conf/menu.lst configuration file. Then +set the dataset mountpoint property to 'legacy'. + + $ grub.conf/menu.lst: kernel ... root=ZFS=pool/dataset + $ zfs set mountpoint=legacy pool/dataset + +3) To set zfs module options put them in /etc/modprobe.d/zfs.conf file. +The complete list of zfs module options is available by running the +_modinfo zfs_ command. Commonly set options include: zfs_arc_min, +zfs_arc_max, zfs_prefetch_disable, and zfs_vdev_max_pending. + +4) Finally, create your new initramfs by running dracut. + + $ dracut --force /path/to/initramfs kernel_version |
