If look well, you are missing nfsexport in the second services <div class="gmail_quote">2012/5/14 Randy Zagar <<a href="mailto:zagar@arlut.utexas.edu" target="_blank">zagar@arlut.utexas.edu</a>> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div bgcolor="#FFFFFF" text="#000000"> I have an existing CentOS-5 cluster I've configured for High-Availability NFS (v3). Everything is working fine. I've included a simplified cluster.conf file below. I originally started with 3 file servers that were not clustered. I converted to a clustered configuration where my NFS Clients never get "stale nfs" error messages. When a node failed, all NFS exports (and their associated IP address) would move to another system faster than my clients could time out. I understand that changes to the portmapper in EL6 and NFSv4 make it much more difficult to configure HA-NFS and, so far, I have not seen any good documentation on how to configure a HA-NFS configuration in EL6. Does anyone have any suggestions, or links to documentation that you can send me? -RZ p.s. Simplified cluster.conf file for EL5... <blockquote> <pre><?xml version="1.0"?> <cluster alias="ha-nfs-el5" config_version="357" name="ha-nfs-el5"> <fence_daemon clean_start="0" post_fail_delay="0"
