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.<br>
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?<br><br>Matt Temple<br><div class="gmail_extra"><br clear="all">------<br>Matt Temple<br>

The connection break behavior is to be expected - the TCP<br>
connection<br>
doesn't handle the switch of host. I didn't expect the NFS<br>

I can't answer this directly but I did notice something in the 3.3.1<br>
change<br>
log which might be relevant:<br>

"nfs: make NFS filehandles deterministic<br>
<br>
If you're not on 3.3.1 already, it could be worth trying.<br>

<br>
Thank you. I have just realized that there's a built-in NFS server -<br>
but I set this up with the /etc/exports.<br>
<br>
I'll try to use the built-in and see if the problem persists, then try<br>
3.3.1 if it does.<br>

<br>
So I tried to use the default NFS settings, with no luck.<br>
Then I upgraded to 3.3.1, still with no luck.<br>
<br>
Seems like the NFS connection is unable to perform a failover. I would really love to hear if someone have this working.<br>
<br>
The reason I want this is to use glusterfs to store virtual machines for VMware.<br>
