Also Gluster have the same tip here:

• Add the following lines to the [global] section of your Samba 
configuration
clustering = yes
idmap backend = tdb2
private dir = /gluster/lock

Can you confirm that "private dir" does *not* have to be set in
smb.conf
to point to a shared FS? If not, would that solve the original problem?

Thanks

No, it does not have to be set. In fact, it is very likely harmful.
ctdb determines where the clustered dbs are located, not samba.

HI Volker,

I've set up the "DR" side of my cluster to "use mmap =
no" and with
"private dir" removed from the smb.conf.

However I still have huge CPU utilisation from winbindd and smbd just
fromtrying to long in a single test XP machine.

I have the MooseFS guys on the case as well. Should I put them in touch
with you or vice/versa?

Many thanks for your gracious assistance,

Alex
