[PATCH]The abolition of distinguishing a node name by a small and capital letter.

Hi,

We committed the following mistakes.

* The host name is a small letter.
* The host name of RULE is a capital letter.
* The host name of STONITH(hostlist) is a capital letter.

By this setting, the resource is arranged definitely, but fails in STONITH(fence opration).

The cause is STONITH distinguishes a node name by a small and capital letter, and to process it.
I think that it is good not to distinguish it in the same way as rule setting.

I created a patch for stonithd.
But, the part revision of stonith-RA becomes necessary for the solution of the problem, too.

I show a revision example of RA of ssh/external next.

---- external/ssh ----------------
reset)
h_target=`echo $2 | tr A-Z a-z`
for h in $hostlist
do
h_list=`echo $h | tr A-Z a-z`
if
[ "$h_list" != "$h_target" ]
then
continue
fi
----------------------------------

Please teach it if there is the revision method that, besides, is good.

Best Regards,
Hideo Yamauchi.

Hi Dejan,

About this matter, how do you think?
Please tell me your opinion.

Hi Hideo-san,

Sorry, missed somehow this post.

You mean converted to lowercase. Yes, somebody even complained
about it lately.

What is "RULE"?

I can't really follow. Can you please give me an example.

I understand that there is somewhere a mismatch in hostname case
handling, but still don't know where.

Re: [PATCH]The abolition of distinguishing a node name by a small and capital letter. [In reply to]

Hi Dejan,

> What is "RULE"?

It is a description of rule in cib.xml.

> I can't really follow. Can you please give me an example.

OK.

It is assumed that there are two nodes.(hostname : node-a and node-b)
The user can write a node name in rule of cib.xml in capital letters.

-------------------------------------------------------------------------
<rsc_location id="domU-xen1-node1" rsc="domU-xen1">
<rule id="domU-xen1-node1-rule-1" score="200">
<expression attribute="#uname" id="domU-xen1-node1-rule-1-expression-1" operation="eq"
value="NODEA"/>
</rule>
</rsc_location>
<rsc_location id="domU-xen1-node2" rsc="domU-xen1">
<rule id="domU-xen1-node2-rule-1" score="100">
<expression attribute="#uname" id="domU-xen1-node2-rule-1-expression-1" operation="eq"
value="NODEB"/>
</rule>
</rsc_location>
-------------------------------------------------------------------------

Rule works definitely.

But, hostlist of stonith does not work definitely when I wrote it in capital letters.

-------------------------------------------------------------------------
<primitive class="stonith" id="Stonith1" type="external/ibmrsa-telnet">
<instance_attributes id="prmStonith1-2-instance_attributes">
<nvpair id="prmStonith1-2-priority" name="priority" value="2"/>
<nvpair id="prmStonith1-2-stonith-timeout" name="stonith-timeout" value="60s"/>
<nvpair id="prmStonith1-2-ip_address" name="ip_address" value="192.168.18.115"/>
<nvpair id="prmStonith1-2-nodename" name="nodename" value="NODEA"/>
(snip)
-------------------------------------------------------------------------

Hideo Yamauchi.

Are node names uppercase? And then stonith doesn't work?

Re: [PATCH]The abolition of distinguishing a node name by a small and capital letter. [In reply to]

Hi Dejan,

> Are node names uppercase? And then stonith doesn't work?

The node name is a small letter.
stonith acts, but it is not carried out because it is not found an target node.

It is caused by a mistake of the setting obviously.
However, for a user, some kind of measures are necessary.

Hideo Yamauchi.

Hm. let me try to summarize my understanding of this thread.

Hostnames are in general case insensitive.

In pacemaker/openais/heartbeat, in most places, this is correctly taken
care of by using strcasecmp(3) or tolower(3) in C code where
appropriate.

some stonith plugins however seem to be case sensitive,
and will just break when one uses hostnames with inappropriate case.

Hideo-san proposes to fix that stonith plugin,
to make it deal with hostnames case insensitive as well
(as the rest of the cluster stack and dns and whatever does),
but to warn about the fact that there is some case mismatch between
spelling in some config file and "hostlist detection" of the stonith plugin.

Hideo-san,
if my understanding of your proposal is correct,
then I think that should just be done.
makes the code more robust,
follows principle of least surprise etc.

there may even be plugins that can only "autodetect" in all caps
because of limitations in the firmware of the hardware used.
I don't know.

but either folding hostnames to all lowercase,
or using strcasecmp, sounds reasonable.

Thanks,

Correctly :) We have a bugzilla open for this, because it
breaks configurations with node names which contain uppercase
letters. But I doubt that that will be fixed. Basically, the only
way is to just have lowercase host names.

My understanding was that the user placed uppercase node names in
the stonith configuration, but the node names are actually
lowercase. But if your understanding is correct, then we may fix
this.

Right, could be, but that should be dealt with in the plugin.

Yes, though that means changing all plugins.

Hi all,

Thank you for understanding of all of you.

I can assist the revision of the plug in.

That would be great since I'm overwhelmed with other business now.
And please open a bugzilla if there isn't any so that we can
track this.
