I've been using DRBD with OCFS2 on top. It's been very stable. No file system corruption. We have had some issues with DRBD rebooting the nodes, but I think those were more related to network problems that caused each node to think the other was offline.
Overall it's been pretty stable. bb On Tue, Mar 27, 2012 at 7:57 PM, Mathew Snyder <[email protected]> wrote: > On Tue, Mar 27, 2012 at 7:52 PM, Mathew Snyder <[email protected]> > wrote: >> On Tue, Mar 27, 2012 at 7:00 PM, Robert Hajime Lanning >> <[email protected]> wrote: >>> On 03/27/12 15:17, Miles Fidelman wrote: >>>> Mathew Snyder wrote: >>>>> Has anyone ever implemented this in a virtual environment?
