#
# Configure NFS backend for Cinder
#
#
# === Parameters
#
# [*nfs_servers*]
# (required) Array of NFS servers in the form 'ipaddress:/share'
#
# [*nfs_mount_options*]
# (optional) Mount options passed to the nfs client. See section
# of the nfs man page for details.
# Defaults to undef
#
# [*nfs_disk_util*]
# (optional) Use du or df for free space calculation
# Defaults to undef
#
# [*nfs_sparsed_volumes*]
# (optional) Create volumes as sparsed files which take no space.
# If set to 'false' volume is created as regular file.
# In such case volume creation takes a lot of time.
# Defaults to undef
#
# [*nfs_mount_point_base*]
# (optional) Base dir containing mount points for nfs shares.
# Defaults to undef
#
# [*nfs_shares_config*]
# (optional) File with the list of available NFS shares.
# Defaults to '/etc/cinder/shares.conf'
#
# [*nfs_used_ratio*]
# (optional) Percent of ACTUAL usage of the underlying volume
# before no new volumes can be allocated to the volume destination.
# Defaults to 0.95
#
# [*nfs_oversub_ratio*]
# (optional) This will compare the allocated to available space on
# the volume destination. If the ratio exceeds this number, the
# destination will no longer be valid.
# Defaults to 1.0
#
