Hi,
did anybody succeed in installing / compiling DRBD for CentOS8? It seems
to cause some trouble in my setup.

Hi,
I set up a mariadb on CentOS7 as master/slave-.
Manually the sync works.
when I confiure a ms resource in pacmaker, it comes up correctly on the
first glance.
"show master status" and "show slave status" in mysql works and shows
the correct status.
When I set the master node to standby
Hi,
When I read the documentation of the colocating sets of of resources,
the last "note" section reads:
Pay close attention to the order in which resources and sets are listed.
While the colocation dependency for members of any one set is
last-to-first, the colocation dependency for multiple s

Hi,
we have a cluster with several IP addresses that can start after an other
resource. In the logs we see that only 2 IP addresses start in parallel, not
all. Can anyone please explain, why not all IP addresses start in parallel?

hi,
the idea of a new cluster meeting is great. I'd like to participate. But the
date 6./7. Sept is not optimal . It is school holidays in Bavaria and the best
time of the year to go to the mountains with the kids.
So I'd prefer perhap
that is not possible. corosync and pacemaker are not able to run as multi-
tennen.
Use docker or plain linux partitions (lxc).

Please check the ARP tables of your switches / routers. IP address clones
use multicast MAC addresses for
not like that. You would have to configure the MAC addresses manually.

server at each site?
So having three servers all together?

run.
pacemaker could take care that they run on different hosts is possible.

No. the cluser is event-based. So it won't miss any event. If you use the
cluster's tools, they see hte events. If you monitor the events you won't miss
any either.

free space on a partition or something like that.
If you want to check a resource (application) then you have to improve the
monitoring function of the according Resource Agent.

Hi,
perhaps this question was answered elsewhere, but I count not find any
satisfying answer. So is it possible to set uo a corosync/pacemaker cluster
that detects errors and does the failover in a sub-second time span?
if yes, how?

Yes. Just configure location constraints so that resources will not run on the
