Description of problem:

My nfs share I've setup on RHEL6 Cluster Suite does in fact work... however, it keeps "failing":

Jan 18 15:49:50 cdtg-rtp-sun-1 rgmanager[6559]: Recovering failed service service:CDTG-NFS-share
Jan 18 15:49:51 cdtg-rtp-sun-1 rgmanager[23610]: Adding export: xxx.18.188.0/25:/data/cluster-storage/ (fsid=40050,rw)
Jan 18 15:49:51 cdtg-rtp-sun-1 rgmanager[23683]: Adding IPv4 address xxx.18.188.202/25 to bond0
Jan 18 15:49:54 cdtg-rtp-sun-1 ntpd[6419]: Listening on interface #1969 bond0, xxx.18.188.202#123 Enabled
Jan 18 15:49:54 cdtg-rtp-sun-1 rgmanager[6559]: Service service:CDTG-NFS-share started

From another machine, I can see that the NFS service is up:
#showmount  -e xxx.18.188.202
Export list for xxx.18.188.202:
/data/cluster-storage xxx.18.188.0/25

... then about a minute later...

Jan 18 15:51:00 cdtg-rtp-sun-1 rgmanager[24355]: nfsclient:CDTG-NFS-Service is missing!
Jan 18 15:51:00 cdtg-rtp-sun-1 rgmanager[6559]: status on nfsclient "CDTG-NFS-Service" returned 1 (generic error)

Jan 18 15:51:20 cdtg-rtp-sun-1 rgmanager[6559]: Service service:CDTG-NFS-share is recovering
Jan 18 15:51:24 cdtg-rtp-sun-1 rgmanager[6559]: Service service:CDTG-NFS-share is now running on member 2

... why is this?  The export works, but is continuously failed-over by rgmanager on both nodes! :-(

Not sure if this has any bearing on the issue, but I found this similar complaint:

Comment 4 joshua 2011-01-18 22:51:05 UTC 
The xxx.18.188.202 IP address didn't have a hostname before, and and such "clufindhostname -i xxx.18.188.202" would fail with error code 2.  I've added a reverse lookup entry for it, and the clufindhostname is much happier now, and exists with error code 0.  However, this doesn't stop the failing-over of an otherwise working service from happening.

Ah ha -

clufindhostname is not working right; also, remove the trailing slash from your mount point name in your fs resource.
