HI, Fabian -
I've been toying aroudn with both NFS and GFS, but NFS does leave me with a single point of failure. I'd rather not use something like drdb, however. I'm still researching GFS to see if it's a viable alternative for what I'm looking for.
Thanks! -dant
GFS can do the job, but in this case you should have a real shared storage to permit all the servers to access the shared data in the same time ... If you don't want to invest a lot, you can still use iscsi but the single point of failure still exists ...
