# The 'cluster' variable determines the name of the cluster.
# Changing the default value to something else means that you will
# need to change all the command line calls as well, for example if
# your cluster name is 'foo':
# "ceph health" will become "ceph --cluster foo health"
#
# An easier way to handle this is to use the environment variable CEPH_ARGS
# So run: "export CEPH_ARGS="--cluster foo"
# With that you will be able to run "ceph health" normally

# ENTERPRISE VERSION RED HAT STORAGE (from 1.3)
# This version is only supported on RHEL >= 7.1
# As of RHEL 7.1, libceph.ko and rbd.ko are now included in Red Hat's kernel
# packages natively. The RHEL 7.1 kernel packages are more stable and secure than
# using these 3rd-party kmods with RHEL 7.0. Please update your systems to RHEL
# 7.1 or later if you want to use the kernel RBD client.
#
# The CephFS kernel client is undergoing rapid development upstream, and we do
# not recommend running the CephFS kernel module on RHEL 7's 3.10 kernel at this
# time. Please use ELRepo's latest upstream 4.x kernels if you want to run CephFS
# on RHEL 7.

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

## Ceph options
#
# Each cluster requires a unique, consistent filesystem ID. By
# default, the playbook generates one for you and stores it in a file
# in `fetch_directory`. 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.
fsid: "{{ cluster_uuid.stdout }}"
generate_fsid: true

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"
#
# For OpenStack on Ubuntu or Debian, set:
#    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
