Requirements

Ceph repo must exist in ../ceph location
Ceph vstart cluster must be running
Read permissions on keyring
- # chmod +r ../ceph/build/keyring
Libvirt
- # zypper install libvirt-devel libvirt-daemon
- # systemctl enable libvirtd
- # systemctl restart libvirtd
Vagrant
- # zypper in ruby-devel gcc make zlib-devel
Optionally, virtual machine manager can be useful
- # zypper in virt-manager

Setup

Get the opensuse-leap-15.1 vagrant box:

# Go to https://download.opensuse.org/repositories/home:/rjdias:/branches:/home:/jloehel:/vagrant:/images/images_leap_15_1/
# Copy the <VAGRANT_BOX_URL> for the `.vagrant.libvirt.box` file
wget <VAGRANT_BOX_URL>

Add the opensuse-leap-15.1 box to vagrant:

vagrant box add opensuse-leap-15.1 <VAGRANT_BOX_FILENAME>

Install the vagrant-libvirt plugin

vagrant plugin install vagrant-libvirt

Usage

Start VMs

vagrant up --provider libvirt

If you experience an error while running vagrant up, try the following: - #zypper in libgcrypt-devel - #systemctl stop vboxdrv - #systemctl start nfs - #SuSEfirewall2 off

Accessing VMs

vagrant ssh node1
vagrant ssh node2

Connect to ceph cluster

Each time you restart your vstart ceph cluster, you have to configure /etc/ceph/ceph.conf and /etc/ceph/keyring accordingly, or simply run:

vagrant provision

Configure iSCSI

To configure iSCSI you need to run the following commands:

# As root, on a iSCSI gateway node, start the iSCSI gateway command-line interface:
sudo gwcli

# Create iSCSI target and gateways
cd /iscsi-targets
create iqn.2003-01.com.redhat.iscsi-gw:iscsi-igw
cd iqn.2003-01.com.redhat.iscsi-gw:iscsi-igw/gateways
create node1 192.168.100.201 skipchecks=true
create node2 192.168.100.202 skipchecks=true

Wait a bit, so the creation of gateways can finish.

# Add RBD image and disk
cd /disks
create pool=rbd image=disk_1 size=90G
cd /iscsi-targets/iqn.2003-01.com.redhat.iscsi-gw:iscsi-igw/hosts
create iqn.1994-05.com.redhat:rh7-client
auth username=myiscsiusername password=myiscsipassword
disk add rbd/disk_1
