Slightly OT: Distributed filesystems

[Christian Rishøj]

Hi,

In my previous experience, OCFS2 (on DRBD shared storage) involved a  
rather substantial overhead. I suggest testing such a setup with a  
realistic load before putting it into production.

Also, consider if the added complexity of introducing a distributed  
filesystem (with its distributed lock manager, quorum service et al)  
is really worth what you gain.

Best regards,

Christian
