[Gluster-users] GlusterFS failover with UCarp

We tried using this model with last year with VMWare, and found it to
fail. We were using UCARP. I found a number of places on the web
indicating that UCARP, Gluster, and NFS would work for VMWare storage, but
further discussion really convinced me that the people who proposed it as a
solution could only say that it /should/ work, not that it /would/ work.
The same article proliferated all over the net.
So I wonder if anyone has used it successfully. With that said, CTDB
/looks/ like it should work for that, but does it? Has anyone used it?
