CTDB

[Andrew B. Lundgren]

I am evaluating setting up a several terabyte cluster on Linux.  I am 
currently working to select the cluster software to use and have a few 
questions about CTDB and samba.
 
I guess the first one should be how stable is CTDB?  Would you consider 
it production ready?
 
Given a 4 node cluster, with file A residing on node 2.  When a windows 
client requests file A, how does the data get to it?
 
Will the client go to any random node in the cluster and request the 
file A and then be directed to node 2 to pull the file, or will the file 
be pulled to the random node from node 2 and then sent to the client?  
 
I have not settled on the clustering technology to use.  I think I have 
narrowed a little bit down to lustre, gluster or RHES/CentOS 5 cluster 
file system.
 
I like the fact that RH includes the cluster with the distro.  
I like that from what I can tell, gluster does not require a custom kernel.
I like that lustre is one of the primary test beds for CTDB.
 
Are there any stark differences with CTDB and these clusters that should 
drive a preference of one of them?
 
Thank you!
