[Linux-cluster] high availability with GFS

[Michael Gale]

Hello,

	From your e-mail I am really not sure what your intended goal is ? Do 
you have a shared storage device you want to make accessible through 
what ever Samba server is master ?

Check the list archives ... there is a issue with Samba and GFS, 
something about how Samba caches file metadata. Not sure if it affects 
you or not.

Michael.
