I have installed the openstack one machine with conjure-up, in the start up guide "http://conjure-up.io/docs/en/users/#getting-started" said the localhost recommend "250G SSD with a seperate block device for ZFS. Our recommendation for that device is 100G." , how to setup the 100G ZFS block device to be used in openstack?
Don't know if this helps; but I've found useful informations at https://www.howtogeek.com/175159/an-introduction-to-the-z-file-system-zfs-for-linux/
If you have a second HD (say /dev/sdb) without any partition table and you want tp create a pool named "geek1" this is the command you have top use:
sudo zpool create -f geek1 /dev/sdb
If you are only configuring ZFS because you think you need to do it for a minimal dev install of Openstack, you can skip that.
From a clean install of Ubuntu 16.04.2:
sudo snap install conjure-up --classic
Then you can pretty much go "next next finish" through getting Openstack to run inside LXD. It takes a while to run. Note the Openstack URL on the last page of the procecss. Also, from the main host,
is a helpful command.
If not a clean install of Ubuntu, you might have to clean up juju, lxd, or conjure-up. I prefer the wipe/reinstall method. But a derivative of the following could be useful:
sudo apt-get remove --purge juju sudo apt-get remove --purge conjure-up sudo apt-get remove --purge lxd
