Problem to start hbagent

Hello,

We need to install LINUX-HA MIB with hbagent client on our Linux-HA
cluster (linux ha version 2.1.3 on Redhat 5.1 64 bits).

>From the source package linux-ha heartbeat-2.1.3-22.1.src.rpm, I've
compiled with the following option:

./ConfigureMe configure --enable-snmp-subagent

I obtained a new heartbeat RPM, and I replaced the old one on the two
nodes.

But when I started heartbeat, I obtained the following error:

heartbeat[30489]: 2008/07/01_14:51:10 info: Starting
"/usr/lib64/heartbeat/hbagent -d" as uid 0 gid 0 (pid 30489)

Our configuration file is set with linux-ha v1-style option (crm set to
off).

Is there an option to start hbagent with linux-ha v1-style?

I saw that a patch exists, but for 2.0.6 version
(http://lists.community.tummy.com/pipermail/linux-ha-dev/2006-July/01326
1.html)

Is this patch available for most recent versions?

Or maybe, the hbagent rights are not set correctly (I started it with
root)...

Here is our configuration file:

debugfile /var/log/ha-debug

logfile /var/log/ha-log

logfacility local0

keepalive 2

warntime 30

udpport 694

Thank you.

Sorry to keep you going on that subject...

Is hbagent compatible with Linux-HA in v1-style?

Hi,

hbagent is a SUBagent, that connects to the local AgentX socket. All
SNMP communications (v1, v3) is done by the Master Agent, which is
net-snmp. So your question should be:

Is net-snmp v1 capable?

To answer is: YES!

Michael.

I believe Lienard was referring to Heartbeat v1, not SNMP v1.

While I don't have the answer, his problem was that starting up hbagent in his v1-style cluster fails because it tries to connect to the CIB and since it's a v1 haresources cluster, it obviously can't connect to the non-existent CIB and dies instead.

RE: Problem to start hbagent [In reply to]

It is exactly my problem... I would like to know if there is a way to compile snmp-subagent to allow hbagent to connect to heartbeat v1 (when option crm is set to off). I tried the option --enable-crm=no, but I have errors when hbagent is compiled in that way.
There is however two programs hbagent.c and hbagentv2.c in source package...
Maybe I should ask in linux-ha-dev mailing list?

RE: Problem to start hbagent [In reply to]

Hello,

I've tried to modify linux-ha hbagent.c to disable v2 functions access. But I still can't access to the MIB by snmpwalk...

I think I have only two issues:

- upgrade to linux-ha v2 style

- or used heartbeat old linux-ha version

Did someone test the patch described here (http://lists.community.tummy.com/pipermail/linux-ha-dev/2006-July/013261.html): it enables snmp_subagent to work without CRM, ... but it can only be applied on 2.0.6 version...

Thank you for your responses ... or any other suggestions.

Anne

RE: Problem to start hbagent [In reply to]

I installed the 2.0.6 version with the patch to enables snmp_subagent to work without CRM.
I've no more problems to start hbagent, now :-).

But after configuring snmpd: I get the following error when I start snmpwalk:

rot# snmpwalk -v2c localhost -c public LinuxHA

LINUX-HA-MIB::LinuxHA = No more variables left in this MIB View (It is past the end of the MIB tree)

Do you know what this error means?

Maybe somethink wrong in snmpd configuration?

I added these lines in snmpd.conf:

# create a SNMPv1/SNMPv2 community

rwcommunity public

# this makes the snmpd a master snmp agent, which can

# support AgentX subagents.

master agentx

# this defines your localhost as the trapsink. so traps

# or rather the SNMPv2 informs, will be sent to localhost.

trap2sink localhost

I restarted snmpd service and I can see agentx with netstat command:

netstat -nlp --protocol unix

Active UNIX domain sockets (only servers)

It seems that the hbagent is still not running, so the master agent does not
know anything about the state of the cluster. Did you check if hbagent is
running (ps uax | grep hbagent)?

You have to start hbagent AFTER snmpd.

RE: Problem to start hbagent [In reply to]

To be sure, I've stopped heartbeat and hbagent, then snmpd.

I've started snmpd:

# service snmpd start

Starting snmpd: [ OK ]

Then heartbeat

# /etc/init.d/heartbeat start

Starting High-Availability services:

2008/07/08_11:59:29 INFO: IPaddr Resource is stopped

[ OK ]

I've checked the hbagent daemon:

# ps -ef

...

But snmpwalk still gives the same result:

LINUX-HA-MIB::LinuxHA = No more variables left in this MIB View (It is past the end of the MIB tree)

Could it be permission access problem?

I've had in ha.cf file

apiauth lha-snmpagent uid=root

But I still have the problem...

It seems that the hbagent is still not running, so the master agent does not

know anything about the state of the cluster. Did you check if hbagent is

running (ps uax | grep hbagent)?

You have to start hbagent AFTER snmpd.

Hm. If heartbeat is stopped, why are there still the ehartbeat processes
around? Or did you start heartbeat again?

It could be such a problem. For a test, please do NOT start hbagent from
heartbeat. So please delete that line from ha.cf and restart heartbeat.

Please start hbagent manually from the command line.

/usr/lib/heartbeat/hbagent -d

Please also check snmpd.conf. Is the view the the SNMP client limited to a
part of the OIDs? Please can you post your snmpd.conf WITHOUT the actual
community strings? Thanks.

Well, if you do not let your client look into the etnerprises MIB it really
cannot!

Please consider:
com2sec readonly 1.2.3.4/24 linuxha
group MyROGroup v1 readonly
view all included .1 80
access MyROGroup "" any noauth exact all none none

Please feel free to use an other community string, SNMP version or view. But
beware the .enterprises.linux-ha (1.3.6.1.4.1.4682) is included into the
view!

RE: Problem to start hbagent [In reply to]

Thank you very much!

I've just followed snmp_subagent README, and I've not review the whole snmpd.conf file.

Now I can ask my nodes status :-)

# snmpwalk -v2c localhost -c public LHANodeStatus.2
LINUX-HA-MIB::LHANodeStatus.2 = INTEGER: active(3)

Thanks a lot!

But, I still have a problem :-\
I can't ask resources status in LHAResourceGroupTable (LinuxHA.4)...

# snmpwalk -v2c localhost -c public LinuxHA.4
LINUX-HA-MIB::LHAResourceGroupTable = No Such Object available on this agent at this OID

It seems hbagent can't access to this information...
Any idea why?

Anne

Hi,

what version of linux-ha do you have? There was a problem with an outdated
version. Please try pacemaker.

RE: Problem to start hbagent [In reply to]

I used 2.0.6 version because I would like to have hbagent with no CRM - and a patch was available in that version.
Now, finally we've decided to update our cluster configuration in 2.1.3 with CRM.
Thank you very much for your help, especially for SNMP configuration.
