[Gluster-users] Split Brain?

[Craig Carl]

CountZ -
Some questions to help us troubleshoot -

What version of Gluster?
What is your server /version/kernel?
What is the on-disk filesystem?
Can you md5sum the file on all the storage servers? Is it the same everywhere?

How are you exporting Gluster (Gluster FS, NFS, CIFS, FTP, etc?)
What version of Gluster on the clients, if using it?
What are your clients disti/version/kernel?
If you md5sum the file from a couple of clients are the results the same across the clients and the servers?

Thanks for your help.
