Somanath,
Hi ,
Thanks for your extended support and advise. I would like to give some
background information about my exercise, which will give some fair idea to you
folks.
We are planning to use pacemaker + Corosync + CMAN stack in RHEL 6.5 OS. For
the same, we are trying to collect the source from Clusterlab.
Are you really sure 6.5? AFAIK 6.5 is no longer supported.
Initially we got the Pacemaker and Corosync Source successfully from Clusterlab
and we were unable to fetch the source for CMAN from Cluster lab.
As you suggested, We already tried to use the latest set of Pacemaker with its
prerequisites (Corosync) on top of RHEL 6.5, but it fails due to dependencies
of RHEL 7.x Components (Systemd).
At least corosync 2.x should work just fine on RHEL 6 and there is no
hard dependency on systemd.
So we are requesting you to provide the below information.
Is it possible for me to get the source code for CMAN from Cluster lab ???
(since we are planning to use it for our production purpose, that's why we
don't want to go with Red hat sites (even for Publicly available)).
Take following comment as just my 0.02$. Honestly I would go with what
distribution provides. RHEL 6 is still supported and what is there is
tested by QE/other customers in production. If you decide to go with
newer versions on top of old distro you are on your own and you may face
weird bugs which nobody will really care about much.
Regards,
Honza

Subject: Re: [ClusterLabs] Pacemaker 1.1.12 does not compile with CMAN Stack.

midly put, it's like trying to run with dinosaurs; that version of pacemaker
together with that effectively superseded bundle of other components will
hardly receive any attention in 2019.
But let's assume there's a reason.
but we are unable to achieve that .
Source taken path :
https://github.com/ClusterLabs/pacemaker/tree/Pacemaker-1.1.12
After Extracting, we installed required dependencies as per
README.markdown,
## Installing from source
$ ./autogen.sh
$ ./configure
$ make
$ sudo make install
After performing above task, we are unable to start pacemaker due to
cman stack is unrecognized service.
Well, pacemaker alone won't magically bootstrap these other prerequisites, you
need to take an effort of grabbing them as well.
For CMAN in particular, look here:
https://pagure.io/linux-cluster/cluster/blob/STABLE32/f/cman
https://ftp.redhat.com/pub/redhat/linux/enterprise/6Server/en/RHS/SRPMS/cluster-3.0.12.1-73.el6.src.rpm
# service pacemaker status
pacemakerd dead but pid file exists
#service cman status
cman: unrecognized service
Easy, no /etc/init.d/cman around, for the mentioned reason.
Still, I am not sure how far you'll get, sounds like an uphill battle.
Settling with the rather recent state of development may avoid significant
chunks of troubles, incl. those that were only fixed in later versions of
pacemaker.
Please find the ./configure screenshot of the system:
pacemaker configuration:
Version = 1.1.12 (Build: 561c4cfda1)
Features = libqb-logging libqb-ipc lha-fencing nagios
corosync-plugin cman acls
Prefix = /usr
Executables = /usr/sbin
Man pages = /usr/share/man
Libraries = /usr/lib64
Header files = /usr/include
Arch-independent files = /usr/share
State information = /var
System configuration = /etc
Corosync Plugins = /usr/libexec/lcrso
Use system LTDL = yes
HA group name = haclient
HA user name = hacluster
CFLAGS = -g -O2 -I/usr/include -I/usr/include/heartbeat
-ggdb -fgnu89-inline -fstack-protector-all -Wall -Waggregate-return
-Wbad-function-cast -Wcast-align -Wdeclaration-after-statement -Wendif-labels
-Wfloat-equal -Wformat=2 -Wmissing-prototypes -Wmissing-declarations
-Wnested-externs -Wno-long-long -Wno-strict-aliasing -Wunused-but-set-variable
-Wpointer-arith -Wwrite-strings -Werror
Libraries = -lgnutls -lqb -lplumb -lpils -lqb -lbz2 -lxslt
-lxml2 -lc -luuid -lpam -lrt -ldl -lglib-2.0 -lltdl -lqb -ldl -lrt -lpthread
Stack Libraries = -lcoroipcc -lcpg -lcfg -lconfdb -lcman
-lfenced
Is there anything I am missing in the configure, to get the cman
stack.
I think having "cman" enumerated amongst features might be enough, but once you'll get
past the "cman: unrecognized service" phase, you shall see.
Hope this helps.
