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 Lon Hohberger 2011-03-29 14:27:39 UTC
+++ This bug was initially created as a clone of Bug #592624 +++

Description of problem:

The monitoring of the nfsexports to nfsclinents goes in to an endless loop. See attached syslog.

When using inheritance in the cluster.conf it looks like /usr/share/cluster/nfsclient.sh can't monitor the export properly.

Problem #1: /var/lib/nfs/etab doesn't have a slash '/' at the end of the export path. Yet $OCF_RESKEY_path contains the end slash '/'. When checking if the export is present in:

  cat $tmpfn | tr -d "\n" | sed -e 's/([^)]*)/\n/g' | grep -q \
                "^${OCF_RESKEY_path}[\t ]*.*${OCF_RESKEY_target_tmp}"
        rv=$?
It doesn't match you try to match:


/nfsexport/lv_app               bamse.niceriver.net

with 

^/nfsexport/lv_app/[\t ]*.*bamse.niceriver.net

No so the monitor is exiting with 1 and the whole thing error out.


Problem #2: Ip doesn't work in the target well you try to make it work here.

declare OCF_RESKEY_target_tmp=$(clufindhostname -i "$OCF_RESKEY_target")

but the fact is that the /var/lib/nfs/etab actually contain the IP address so then it's a no go again due to a miss match..


Anyways here is a version that will work :).. for both IP and hostnames as well as with or without ending '/' -- yes could be more brain behind the regexp but I just made it simple.. 


        declare OCF_RESKEY_target_tmp=$(clufindhostname -i "$OCF_RESKEY_target")
        if [ $? -ne 0 ]; then
                [ "$OCF_RESKEY_use_cache" = "1" ] || rm -f $tmpfn
                ocf_log err "nfsclient:$OCF_RESKEY_name is missing!"
                exit 1
        fi

        cat $tmpfn | tr -d "\n" | sed -e 's/([^)]*)/\n/g' | grep -q \
                "^${OCF_RESKEY_path}[\t ]*.*${OCF_RESKEY_target_tmp}"
        rv=$?

        if [ $rv -eq 0 ]; then
                [ "$OCF_RESKEY_use_cache" = "1" ] || rm -f $tmpfn
                exit 0
        fi

        cat $tmpfn | tr -d "\n" | sed -e 's/([^)]*)/\n/g' | grep -q \
                "^${OCF_RESKEY_path}[\t ]*.*${OCF_RESKEY_target}"
        rv=$?

        if [ $rv -eq 0 ]; then
                [ "$OCF_RESKEY_use_cache" = "1" ] || rm -f $tmpfn
                exit 0
        fi

        OCF_RESKEY_path_tmp=$(echo $OCF_RESKEY_path | sed -e 's@/$@@')

        cat $tmpfn | tr -d "\n" | sed -e 's/([^)]*)/\n/g' | grep -q \
                "^${OCF_RESKEY_path_tmp}[\t ]*.*${OCF_RESKEY_target_tmp}"
        rv=$?

        if [ $rv -eq 0 ]; then
                [ "$OCF_RESKEY_use_cache" = "1" ] || rm -f $tmpfn
                exit 0
        fi

        cat $tmpfn | tr -d "\n" | sed -e 's/([^)]*)/\n/g' | grep -q \
                "^${OCF_RESKEY_path_tmp}[\t ]*.*${OCF_RESKEY_target}"
        rv=$?

        [ "$OCF_RESKEY_use_cache" = "1" ] || rm -f $tmpfn
        if [ $rv -eq 0 ]; then
                exit 0
        fi


        ocf_log err "nfsclient:$OCF_RESKEY_name is missing! at end"
        exit 1
        ;;
