Frontend cephfs

• Create both system datastore directories:
  

mkdir -p /onefs/{dc1,dc2}                                                       

• Add system datastores to fstab:
  

10.16.5.40:6789,10.16.5.41:6789,10.16.5.42:6789:/onefs /onefs/dc1 ceph name=one,secretfile=/etc/ceph/dc1.client.   one.key 0 0
10.16.4.40:6789,10.16.4.41:6789,10.16.4.42:6789:/onefs /onefs/dc2 ceph name=one,secretfile=/etc/ceph/dc2.client.   one.key 0 0

• Create datastore symlinks:
  

ln -s /onefs/*/* /var/lib/one/datastores/                                       
chown oneadmin:oneadmin /var/lib/one/datastores/*
