why would this one server be unable to create that file?
If I copy it manually while ctdb is running I see:

50.samba: WARNING: smb.conf cache update failed - using old 
cache file
Node became HEALTHY. Ask recovery master 0 to perform ip 
reallocation

and:

$ ctdb status
Number of nodes:2
pnn:0 10.5.6.32        OK
pnn:1 10.5.6.49        OK (THIS NODE)

but only so far as next stop/restart. What the heck?
