1441447 – Error Moving Cluster Resources

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:

We have a script which either starts our own LSB resources or moves them to the peer node, in a two-node cluster. The move action produces errors, as shown below. The cluster has two nodes: sys70ccg1-app and sys70ccg2-app. There were 16 LSB resources defined and running, most of them on sys70ccg2-app. We tried to move them to sys70ccg1-app using the script. The command we executed was 

    ./activate_cluster_resources_rh7.sh move first_index 1 last_index 16 node sys70ccg1-app

where "activate_cluster_resources_rh7.sh" is the name of our script, enclosed below in its entirety.

Version-Release number of selected component (if applicable): pcs 0.9.152

Additional info:

This is our script, "activate_cluster_resources_rh7.sh":

#!/bin/sh
# Start or move cluster resources
#
# Invocation:
# 
#	activate_cluster_resources_rh7.sh start|move first_index <first_index> [last_index <last_index>] node <node_name>

		# Cleans up the resource in lrmd (useful to reset the resource
        # status and failcount).  This tells the cluster to forget the
        # operation history of a resource and re-detect its current state.
        # This can be useful to purge knowledge of past failures that have
        # since been resolved. If a resource id is not specified then all
        # resources/stonith devices will be cleaned up.
		pcs resource cleanup ${RESOURCE_BASE_NAME}${index}

[root@sys70ccg1 cluster_scripts]#

The same command works in our test lab, using pcs 0.9.143.

Comment 2 Ken Gaillot 2017-04-25 21:10:42 UTC

Reassigning to pcs component. I don't think it's related to the specific script here; it looks like something internal to pcs, possibly in combination with some environmental settings here.

The problem is with the --wait flag: it is internally converted to an int and then this int is put into subprocess.Popen.

Comment 4 Radek Steiger 2017-04-26 08:06:13 UTC

This is a known bug: bz1422667

Comment 5 Tomas Jelinek 2017-04-26 10:59:15 UTC

Support for --wait in the cib-push command has been added in pcs 0.9.152 and the bug was introduced in the very same patch. Therefore this is not a regression. Before pcs 0.9.152 the --wait flag was completely ignored in the cib-push command.
