Hi,
hope you guys can help me,
we have builded up a rabbitmq cluster using pacemaker resource called
rabbitmq-cluster.
everything works as exptected till for maintenance reason, we shutted down
the entire cluster gracefully.
at the startup we noticed all the user and permissions were dropped and
It could be the watchdog? Are u using diskless watchdog?Two nodes are not

Hi guys,
im trying to create a IPaddr2 cloned resource for one of my project.
i need some kind of simple but effective loadbalancer for my rabbitmq

My current SO is Almalinux 8.6.

because

If I would have only 3 nodes where I clustered MySQL with galera how then I
have to point my application to the right nodes?

Probably I'm going to try drbd on very small and low usage db.
Thanks for sharing the doc.
More I know about MySQL more postgresql seems have better replication at
least for me.

Hi guys, I'm about to figure out how setup a pacemaker cluster for MySQL

I'm super new about MySQL and also it's replication method but I'm very
experienced related postgres cluster using PAF.
Diggin the web I found out many different way to achieve.

Seems you are not using any fencing / stonith mechanism. A cluster is not
fully functional without it.

Related my experiences, i would say absolutely yes. Fecing is needed to
keep integrity of the cluster if something goes suddenly and unexpected
wrong, even in a 2nodes+qdevice setup. I never seen a cluster without
fecing working properly.

Hello everybody,
I would need some clarification regarding the backup system I was asked to
implement.
the current configuration is as follows:
3 servers where a postgres cluster with PAF
1 server where the backup and its incrementals must be stored
my idea is to use pg_basebackup and then back
got few fully working cluster with PAF 2.3.0 and postgres13, probably your
configuration is not working correclty.

Ehy,
Take in account when a master node crash, you should re-allign the old
master into the slave using pg_basebackup/pg_rewind and then rejoin the
node into the cluster as a slave. This is the only way to avoid data
corruption and be sure the new slave is correcly synchronised with the new

hi guys thanks for supporting.
the time query isnt the problem, is known that took its time. the network
is 10gbs bonding, quite impossible to sature with queries :=).
the servers are totally overkilled, at database full working loads 20% of
the resources have been used.

Hi guys,
im back with some PAF postgres cluster problems.
tonight the cluster fenced the master node and promote the PAF resource to
a new node.
everything went fine, unless i really dont know why.
so this morning i noticed the old master was fenced by sbd and a new master
was promoted, this
of free hdd space.
how you guys suggest me to find out why the monitor timed out?
Really thanks for your support.

sorry for bothering, unfortunally i was called for an issue related to a

Personally i discourage the use of the auto restarts/rejoin, if something
wrong happened, better investigate the causes and then enable the failed
node again.
failovers shouldnt occour frequently, only if something went really bad: as
far i know, pacemaker and PAF doesnt support any kind of
Could be an idea to let your cluster start it on all your nodes

Hi,
Have you correcly configure a working fencing mechanism?without it you cant
rely on a safe and consistent environment.
My suggestion is to disable the autostart services (and so the autojoin
into the cluster) on both nodes.
if there is a fault you have to investigate before you rejoin the

Hi jaikumar,
Ilo/sbd fencing should provide node reboot in case of network split. Is
your node properly fenced?
Anyway if your cluster is managing a db services like postgres as
replication throught wal log when a failover occurs you MUST resync or
pg_rewind in order to guarantee the cosistency.
