This is an update post to making an Ubuntu 14.04 (Trusty Tahr) OS work with ZFS root volume. Mostly the instructions remains the same as a previous post so this is a shortened version:
\nhttp:\/\/blog.ls-al.com\/booting-ubuntu-on-a-zfs-root-file-system\/<\/p>\n
Small warning I did this 4 times. It worked the first time but of course I did not document it well the first time and when I tried again I had grub issues.<\/p>\n
Step 1:<\/span><\/strong><\/p>\n ** Don't need grub ppa as per github instructions???<\/span><\/p>\n ** Will take quite a while kernel modules compiles!!<\/span><\/p>\n Step 2:<\/strong><\/span><\/p>\n ** Make partitions as follow<\/p>\n Step 3:<\/strong><\/span><\/p>\n Step 4:<\/strong><\/span><\/p>\n WTF: ** System seems hung. I see on a different terminal there was a messages system restart required. Weird. If you get this after debootstrap you have to redo Step 1 and Step 4.1 then...Is this because of only 2G RAM?<\/span><\/p>\n Step 5:<\/strong><\/span><\/p>\n Quick note on grub issues. \u00a0During the install I had to create soft links since I could not figure out the grub-probe failures. \u00a0From memory I think I created soft links as follow and purged grub2-common grub-pc and re-installed:<\/p>\n Update 5.6.14:<\/span> \u00a0After I had time to look at it closer I see my grub issues all came from the fact that there is no trusty grub ppa and the apt-add-repository command above is setting up a trusty repo. \u00a0Quickest way to fix this is after the apt-add-repository --yes ppa:zfs-native\/grub command fix the file manually to use raring. As follow:<\/p>\n Now ready to continue on.<\/p>\n Step 6:<\/strong><\/span><\/p>\n Step 7:<\/strong><\/span><\/p>\n Post First Reboot:<\/span><\/strong> TODO:<\/strong><\/span> This is an update post to making an Ubuntu 14.04 (Trusty Tahr) OS work with ZFS root volume.

\n- Made a VB snapshot of course
\n- apt-get install ubuntu-desktop
\n** grub issues again so I remade the link again. Later fixed with the grub ppa repo pointing to raring instead.
\n- create a user
\n- install VB Guest Additions<\/p>\n
\n- Check into grub issue and having to create soft links. Something to do with grub not following soft links.<\/p>\n","protected":false},"excerpt":{"rendered":"
