Re: [Pacemaker] A function demand of the new environment.

Hi Andrew,

Yes. 
For the realization of the function to assure the practice of the resources of 
the cluster, we use
respawn.

We found the function that it might be replaced of respawn in a road map of 
OpenAIS/Corosync.
It seems to be a function such as the simple version of the CPG service.
But, the function does not yet become clear. 
Let me discuss it again after confirming development of Corosync/OpenAIS about 
this matter.

Best Regards,
Hideo Yamauchi.

Re: [Pacemaker] trying to import a constraint

[Shravan Mishra]

I just found my problem, so here it is in case someone spends a couple
of hours like me to figure out why it's not working

The culprit is -X, don't use that.

The correct command is :
cibadmin -o constraints -C  -p << END

  
  
  
 
 END

[Pacemaker] trying to import a constraint

[Shravan Mishra]

Hi guys,
Below is a partial snippet of my config:

 =

  

  

  
  

  

  

 
  

===


When I try doing :

cibadmin -o constraints -C  -X -p << END

 
  
 

END

I get

"Couldn't parse input from input string."

What is not parseable here?

Re: [Pacemaker] CRM help

[Eliot Gable]

Yes, files are there. See my first post. Ran ocf-tester on mysql RA and get 
this:

/usr/lib/ocf/resource.d/heartbeat/mysql passed all tests

But, after modifying the crm Python code to uncomment one of the error 
messages, I see this:

crm(live)configure#  primitive mysql ocf:heartbeat:mysql
ERROR: could not parse meta-data for (ocf,mysql,heartbeat)
ERROR: ocf:heartbeat:mysql: no such resource agent

Why would CRM not be able to parse the meta-data while the ocf-tester script 
seems to like the RA and it's meta-data just fine?

Re: [Pacemaker] CRM help

[Eliot Gable]

Ok, I figured out I need to change the clone to primitive to define the thing 
first and then reference the primitive using the clone command. I now no longer 
get the object does not exist message, but it now says it cannot find the 
resource agent:

ERROR: ocf:heartbeat:postgresql: no such resource agent

Ok, that still does not work. When I run the script, it just sits there and 
does nothing (does not even return me to the prompt). When I hit CTRL-C to try 
to terminate it, it just gives me the same errors I was getting before about 
ocf:heartbeat:apache and etc not existing. But I have to keep hitting CTRL-C 
for each line until it gives me all errors and then it exits.

The documentation clearly shows doing it the way I first posted.

Re: [Pacemaker] CRM help

[Johan Verrept]

Ah. you could also try this:

primitive apacheserver ocf:heartbeat:apache params
configfile=/etc/httpd/httpd.conf
clone apache apacheserver meta clone-max="2"

No guarantees this is 100% correct (i didn't try) but you should get the
idea of what is wrong.

Anyway, if you are creating a script for an existing configuration, try
"crm configure show"

That's on the todo list, I've even started working on it, but then had
an issue with funny way resource sets are constructed in CIB. We had a
discussion about that last year.

There are no shell constructs which are rendered as two or more CIB
elements. I guess that this should be possible, but really can't say
until I take a thorough look at the implementation. BTW, I guess that
there are other CIB phrases which are commonly in use.

Remember to not use any shared storage in this environment.

BTW, if you had configured the primitive resource via the CRM shell,
you'd have gotten this info message on the first attempt ;-)

Well, if you want to ssh in, there's the

[Pacemaker] Pacemaker Build Issues on CentOS 5.3 64-bit

[Eliot Gable]

When building Pacemaker (1-0-78e8ab00359a) on CentOS 5.3 64-bit, I run into all 
sorts of errors. First, the compiler flag '-Werror' is enabled. On CentOS 5.3, 
gcc issues a warning when you drop a const qualifier on a pointer, which 
Pacemaker code seems to do all over the place (why does it do that, btw? It 
breaks good coding practices); so gcc terminates compilation of Pacemaker when 
encountering these issues.

Once I modify configure.ac to remove this flag and regenerate everything, I run 
into linking errors because the Makefile LIBS= line tells Pacemaker to use 
/usr/lib and /lib64 instead of /usr/lib64 and /lib64. I tried to fix this in 
configure.ac, but I'm not really an expert when it comes to manipulating 
configure.ac files, so I couldn't get it to work. Instead, I find myself 
manually modifying nearly every Makefile that gets generated to make it use 
/usr/lib64 instead of /usr/lib.

If someone could fix these issues quickly, it would save everyone using CentOS 
lots of time and headache trying to make this work. :) I would be more than 
happy to test any modifications for anyone willing to try to fix it.

[Pacemaker] Remote managmenet of a cluster

[Michael Schwartzkopff]

Hi,

I haven't been able to find too much documentation about the managenemt of a 
cluster from a remote machine by CLI (crm subshell or cibadmin). Any hint for 
me where I can find more information about the stuff?

I only found a thread on the mailing list indicating that the remote 
management is not in a very good shape right now. Is this impression correct? 
Any good howto?

Thanks,

Michael.

[Pacemaker] RFC: Compacting constraints

[Lars Marowsky-Bree]

Hi all,

I have a pretty common use case - 4-16 nodes with OCFS2 etc, hosting a
ton of Xen/KVM guests.

Compacting the OCFS2 setup was pretty easy -
http://www.advogato.org/person/lmb/diary.html?start=104 - and that part
seems short enough. 

For each guest, I need an order and collocation constraint with the base
resources, which becomes complex and lengthy very quickly. Just to
illustrate my point:

colocation dummy1-c inf: base-clone dummy1
colocation dummy10-c inf: base-clone dummy10
colocation dummy11-c inf: base-clone dummy11
colocation dummy12-c inf: base-clone dummy12
colocation dummy13-c inf: base-clone dummy13
colocation dummy14-c inf: base-clone dummy14
colocation dummy15-c inf: base-clone dummy15
colocation dummy16-c inf: base-clone dummy16
colocation dummy17-c inf: base-clone dummy17
colocation dummy18-c inf: base-clone dummy18
colocation dummy19-c inf: base-clone dummy19
colocation dummy2-c inf: base-clone dummy2
colocation dummy3-c inf: base-clone dummy3
colocation dummy4-c inf: base-clone dummy4
colocation dummy5-c inf: base-clone dummy5
colocation dummy6-c inf: base-clone dummy6
colocation dummy7-c inf: base-clone dummy7
colocation dummy8-c inf: base-clone dummy8
colocation dummy9-c inf: base-clone dummy9
order dummy1-o 0: base-clone dummy1
order dummy10-o 0: base-clone dummy10
order dummy11-o 0: base-clone dummy11
order dummy12-o 0: base-clone dummy12
order dummy13-o 0: base-clone dummy13
order dummy14-o 0: base-clone dummy14
order dummy15-o 0: base-clone dummy15
order dummy16-o 0: base-clone dummy16
order dummy17-o 0: base-clone dummy17
order dummy18-o 0: base-clone dummy18
order dummy19-o 0: base-clone dummy19
order dummy2-o 0: base-clone dummy2
order dummy3-o 0: base-clone dummy3
order dummy4-o 0: base-clone dummy4
order dummy5-o 0: base-clone dummy5
order dummy6-o 0: base-clone dummy6
order dummy7-o 0: base-clone dummy7
order dummy8-o 0: base-clone dummy8
order dummy9-o 0: base-clone dummy9


There's a bunch of open issues (resource_sets not supporting score="0",
the crm shell not supporting resource_sets at all), but I'd even more
prefer if I didn't have to have both the order and collocation
constraints.

Could we introduce an "conjoin" dependency which merges both? I don't
much care whether this is done at the XML/CIB level, or at the shell
level (detect duplication and merge for the shell syntax - the advantage
would be that none of the other CIB consumers would need to be taught
about it); it should allow, of course, to specify both the ordering and
collocation scores.

So, I'd imagine that the above could be represented in the shell syntax
as:

conjoin dummies-dep base-clone {dummy1, dummy2, dummy3, ...} \
meta score_collocation=infinity score_order=0


This would be an extremely desirable usability improvement, IMNSHO. I
welcome your feedback.


Regards,
Lars

Even with respawn, the node still has to become a full cluster member
and complete resource probing before the respawned processes can have
any effect.

But we don't really encourage that anymore either.
Certainly no-one else running openais based clusters has seemed overly
concerned about being forced to run it as a resource.

You just have to write your rules so that the cluster produces the
"correct" behavior when no value exists for your attribute(s).

Or are you looking for the ability to do more than simply prevent
resources from running?

Re: [Pacemaker] how to run a remote script [SOLVED]

[gilberto migliavacca]

Hi

I solved the problem using the APACHE for the moment

I created the the apache resource and the ip resource
qith the crm command line tool

than with the crm resource start  command
I can start (and after that stop) the apache server
on the node

there was a problem with the APACHE installation
I found the solution in the mailing list.
the apache agent fails when tried to call the

sh -c wget -O- -q -L --no-proxy --bind-address=127.0.0.1 
http://localhost:80 .


I removed the welcome.conf that causes the problem

I guess heartbeat wasn't hung then... otherwise it would have stopped

That would be handy.
I'd be interested to know what each Pacemaker process was up to at the time.

Oh, were you logging to a file or syslog?  That might have some impact.
