# CEPH CONFIGURATION #
######################

## Ceph options
#
# Each cluster requires a unique, consistent filesystem ID. By
# default, the playbook generates one for you.
# If you want to customize how the fsid is
# generated, you may find it useful to disable fsid generation to
# avoid cluttering up your ansible repo. If you set `generate_fsid` to
# false, you *must* generate `fsid` in another way.
# ACTIVATE THE FSID VARIABLE FOR NON-VAGRANT DEPLOYMENT
fsid: "{{ cluster_uuid.stdout }}"
generate_fsid: true

ceph_conf_key_directory: /etc/ceph

# Permissions for keyring files in /etc/ceph
ceph_keyring_permissions: '0600'

cephx: true

## Client options
#
rbd_cache: "true"
rbd_cache_writethrough_until_flush: "true"
rbd_concurrent_management_ops: 20

rbd_client_directories: true # this will create rbd_client_log_path and rbd_client_admin_socket_path directories with proper permissions

# Permissions for the rbd_client_log_path and
# rbd_client_admin_socket_path. Depending on your use case for Ceph
# you may want to change these values. The default, which is used if
# any of the variables are unset or set to a false value (like `null`
# or `false`) is to automatically determine what is appropriate for
# the Ceph version with non-OpenStack workloads -- ceph:ceph and 0770
# for infernalis releases, and root:root and 1777 for pre-infernalis
# releases.
#
# For other use cases, including running Ceph with OpenStack, you'll
# want to set these differently:
#
# For OpenStack on RHEL, you'll want:
#   rbd_client_directory_owner: "qemu"
#   rbd_client_directory_group: "libvirtd" (or "libvirt", depending on your version of libvirt)
#   rbd_client_directory_mode: "0755"

#    rbd_client_directory_owner: "libvirt-qemu"
#    rbd_client_directory_group: "kvm"
#    rbd_client_directory_mode: "0755"
#
# If you set rbd_client_directory_mode, you must use a string (e.g.,
# 'rbd_client_directory_mode: "0755"', *not*
# 'rbd_client_directory_mode: 0755', or Ansible will complain: mode

# igw
#
# `igw_network` variable is intended for allowing dashboard deployment with iSCSI node not residing in the same subnet than what is defined in `public_network`.
# For example:
# If the ceph public network is 2a00:8a60:1:c301::/64 and the iSCSI Gateway resides
# at a dedicated gateway network (2a00:8a60:1:c300::/64) (With routing between those networks).
# It means "{{ hostvars[item]['ansible_facts']['all_ipv4_addresses'] | ips_in_ranges(public_network.split(',')) | last | ipwrap }}" will be empty.
# As a consequence, this prevent from deploying dashboard with iSCSI node when it reside in a subnet different than `public_network`.
# Using `igw_network` make it possible, set it with the subnet used by your iSCSI node.

# DEPRECIATED iSCSI TARGET SETUP #
##################################

# WARNING #

# The following values are depreciated. To setup targets, gateways, LUNs, and
# clients you should use gwcli or dashboard. If the following values are set,
# the old ceph-iscsi-config/ceph-iscsi-cli packages will be used.

# 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_iqn: ""

# 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' }
