RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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 15:51:10 cdtg-rtp-sun-1 rgmanager[24658]: Removing IPv4 address xxx.18.188.202/25 from bond0

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 -

*** This bug has been marked as a duplicate of bug 661881 ***

Comment 6 Lon Hohberger 2011-03-18 15:11:34 UTC
clufindhostname is not working right; also, remove the trailing slash from your mount point name in your fs resource.
