CTDB Design
? one daemon ctdbd on each node
? smbd talks to local ctdbd for messaging and TDB access
? ctdbd handles metadata of TDBs via the network
? ctdbd keeps local TDB copy (LTDB) for fast data reads/writes
? persistent and normal TDBs are handled differently
? management features Samba, NFS and other services
