[Gluster-users] Shared IP address

[Alex Crow]

HI,

Are your PUBLIC_ADDRESSES different from the NODES addresses (they must 
not be used on any real interface)? Is the /mnt/datavol mounted on all 
nodes?

I also found I had to copy /var/lib/samba/private/* to the 
/mnt/datavol/lock area to get samba working.

Cheers

Alex
