# 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

# 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 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.
