Hello,

If I remember correctly, you can increase the ctdb log level in the ctdb 
config file (ctdb.conf). So you may find more info on what is going on.

The last time I used ctdb :
- it was not necessary to have a shared private dir, ctdb maintain a 
database on each node
- you just need to join the whole cluster and not each node individually
- it is possible to let ctdb manage winbind for you (really usefull)

I was using gfs2 on a shared FC disk array. The ping pong test was not 
that fast but the final setup was fast enough for our need.
I remember that during the setup I've started by running a simple http 
server on each node until the FS and network configuration was OK 
(switching on/off each node after the other). I then started to setup 
samba on it.

hope this help
