Red Hat Bugzilla – Bug 113503
[PATCH] Daemon properties won't allow changes in 3-member clusters
Last modified: 2013-09-02 01:53:36 EDT
Description of problem:
When you try to change daemon properties in redhat-config-cluster and
there are 3 cluster members, the daemon properties dialog refuses to
close, cited below. When you select the cluquorumd tab, both
tiebreakers are greyed out - as should be (no tiebreaker is necessary
in odd-number clusters). This problem prevents changing daemon log
levels as well as failover time from the GUI.
"Error: Disk Tiebreaker was selected but no Disk Ping Interval was
entered. Please enter a disk Ping Interval (in seconds) for Disk
Version-Release number of selected component (if applicable): 1.0.1-4
How reproducible: 100%
Steps to Reproduce:
1. Create a cluster with three members in redhat-config-cluster
2. Open daemon-properties dialog box.
3. Click 'OK'.
Actual results: Error message.
Expected results: Should work.
- The error is correct for 2 member clusters.
- The cluster GUI should only check for 'disk tiebreaker' in 2 member
clusters. Perhaps it should have some default value. The cluster
back-end software has a default of 2 seconds for the ping interval.
- The cluster GUI should only check for 'IP tiebreaker' in 2 and 4
member clusters - other supported node counts (3, 5, 6, 7, 8) never
need to check for any tiebreaker, as neither is used.
