I've been trying to install ubuntu with a zfs as root filesystem. But it seems that GRUB 2.xx which has ZFS support doesen't support compression, so i disabled it. However i keep running in to the same problem.
Installing ubuntu is pretty easy, but booting it seems to be a pain in the neck.
After booting the 15.04 live CD i issued the following in the terminal:
Get the zfs support packages installed
# apt-add-repository --yes ppa:zfs-native/stable # apt-get update # apt-get install debootstrap spl-dkms zfs-dkms ubuntu-zfs
Create the zfs pools/datasets
# zpool create -o ashift=12 -m none -R /mnt ospool mirror sdb sdc # zpool create -o ashift=12 -m none -R /mnt storage raidz1 sdd sde sdf sdg sdh # zfs create -o mountpoint=/ ospool/root # zfs create -o mountpoint=/boot ospool/boot # zfs create -V 8G -b 4k ospool/swap # zfs create -o mountpoint=/var storage/var # zfs create -o mountpoint=/home storage/home
Bootstrap the base system, and chrooting in
# debootstrap vivid /mnt # chroot /mnt /bin/bash --login
I have a boot device (SDA) which has an ext2 and a bios boot partition on Mounted on /mnt/boot/grub
At this point i installed the same zfs packages which works just fine. But GRUB fails to install complaining about not being able to find the device og canonical path, so grub2-common and grup-pc never finishes.
So my question is how, do i get grub installed with zfs support?
if i manually install grub with grub-install and reboot into the grub shell, i can see that zfs is supported. But can't reference the kernel with the linux path/to/kernel command.
