# 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

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:

#    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.,
