# Specify the iqn for ALL gateways. This iqn is shared across the gateways, so an iscsi
# client sees the gateway group as a single storage subsystem.

# gateway_ip_list provides a list of the IP Addrresses - one per gateway - that will be used
# as an iscsi target portal ip. The list must be comma separated - and the order determines
# the sequence of TPG's within the iscsi target across each gateway. Once set, additional
# gateways can be added, but the order must *not* be changed.
gateway_ip_list: 0.0.0.0

# rbd_devices defines the images that should be created and exported from the iscsi gateways.
# If the rbd does not exist, it will be created for you. In addition you may increase the
# size of rbd's by changing the size parameter and rerunning the playbook. A size value lower
# than the current size of the rbd is ignored.
#
# the 'host' parameter defines which of the gateway nodes should handle the physical
# allocation/expansion or removal of the rbd
# to remove an image, simply use a state of 'absent'. This will first check the rbd is not allocated
# to any client, and the remove it from LIO and then delete the rbd image
#
# NB. this variable definition can be commented out to bypass LUN management
#
# Example:
#
#rbd_devices:
#  - { pool: 'rbd', image: 'ansible1', size: '30G', host: 'ceph-1', state: 'present' }
#  - { pool: 'rbd', image: 'ansible2', size: '15G', host: 'ceph-1', state: 'present' }
#  - { pool: 'rbd', image: 'ansible3', size: '30G', host: 'ceph-1', state: 'present' }
#  - { pool: 'rbd', image: 'ansible4', size: '50G', host: 'ceph-1', state: 'present' }
rbd_devices: {}

# client_connections defines the client ACL's to restrict client access to specific LUNs
# The settings are as follows;
# - image_list is a comma separated list of rbd images of the form <pool name>.<rbd_image_name>
# - chap supplies the user and password the client will use for authentication of the
#   form <user>/<password>
# - status shows the intended state of this client definition - 'present' or 'absent'
#
# NB. this definition can be commented out to skip client (nodeACL) management
#
# Example:
#
#client_connections:
#  - { client: 'iqn.1994-05.com.redhat:rh7-iscsi-client', image_list: 'rbd.ansible1,rbd.ansible2', chap: 'rh7-iscsi-client/redhat', status: 'present' }
#  - { client: 'iqn.1991-05.com.microsoft:w2k12r2', image_list: 'rbd.ansible4', chap: 'w2k12r2/microsoft_w2k12', status: 'absent' }
