Comment 2 Len DiMaggio 2006-12-08 18:35:32 UTC 
RHEL5 GA requirement = Cluster configuration with Luci, CGA-0200 - Creating a
cluster (http://intranet.corp.redhat.com/ic/intranet/RHEL500ReleaseCriteria#Conga)

Impact statement - the user add the node to the cluster outside of Conga
Comment 3 Len DiMaggio 2006-12-08 18:37:11 UTC 
The text of the error displayed is:  Unable to determine the cluster OS for the
<cluster name> cluster
Comment 5 Ryan McCabe 2006-12-11 15:13:48 UTC 
I have a fix for this that's checked into -HEAD.
Comment 6 Len DiMaggio 2006-12-11 16:08:15 UTC 
That's great Ryan - can you also check on deleting a node from a cluster? It
seems to be broken too.
Comment 7 Ryan McCabe 2006-12-11 16:42:03 UTC 
I just checked with the latest tree (-HEAD), and it is working there.
Comment 8 Stanko Kupcevic 2006-12-13 19:25:57 UTC 
There is also a problem with modclusterd where it seqfaults during "add node"
action (under certain circumstances), making it impossible to complete the
operation. 

Commited to -HEAD and -RHEL5

Comment 9 Len DiMaggio 2007-01-09 17:39:23 UTC 
Stan indicated that this bz was fixed in luci-0.8-26.el5/ricci-0.8-26.el5, but
it's still failing - this error is written to the luci log:

Jan  9 10:41:02 tng3-5 luci[2430]: vACN8: local variable 'e' referenced before
assignment

Is it actually fixed in 0.8.27?
Comment 10 Ryan McCabe 2007-01-09 19:52:59 UTC 
The fix is in -27, not -26.
Comment 11 Len DiMaggio 2007-01-19 17:51:00 UTC 
Verified in:

luci-0.8-29.el5
ricci-0.8-29.el5
