what version of DRBD do you have?

  
It's DRBD 8.0.4. I also noticed that if resources start simultaneously 
in the same time, the file system is mounted properly (on both nodes), 
but if I start pacmekaer-openais on first node and then I will wait a 
couple of seconds and start openais on second node the filesystem on 
that node will not start.


Without pacemaker-openais, when I start manually DRBD on both nodes and 
mount filesystem everything is ok.

What is serwer-mysql? In the last location constraint, serwer-mysql 
should be msDRBD I think. Does msDRBD come up master and slave? Or 
both came up with slave?


Thanks

i want WWW
server to start with assigned virtual IP. My configuaration is
working, but
unfortunately not properl. It turnes on DRBD, assebles files
system, but WWW
server and mysql don't start. crm_mon doesn't show any failed actions.

This is my config:
primitive resDRBD ocf:heartbeat:drbd \
 op monitor role=Master interval=59s timeout=30s \
 op monitor role=Slave interval=60s timeout=30s \
   params drbd_resource="web"

op monitor interval=21s timeout=5s

group server-www virtual-ip lighttpd

order msDRBD-before-cloneOCFS2 inf: msDRBD:promote cloneOCFS2:start

order cloneOCFS2-before-server-www inf: cloneOCFS2:promote
server-www:start


colocation sever-www-on-msDRBD inf: server-www msDRBD:Master

location ms-drbd1-master-on-node2 serwer-mysql \
rule id="ms-drbd1-master-on-node2-rule" role="master" 100: #uname
eq node2


Log doesn't show anything about it.

It's my mistake. There should be server-www. With this configuration 
msDRBD come up master on both nodes always, but if I will not start them 
in the same time the filesystem on the node that start later will not be 
mount (but drbd will be master on both nodes).

I found two issues in your configuration.

1. Still the last location constraint does not make sense. The 
server-www is a group, not multistate master/slave, so role=master is 
wrong. This should be msDRBD.
2. Why did you set max-master=2? As you said, both nodes came up as 
master, most of constraints you configured does not make sense. For 
example, colocation constraints says that server-www must be run with 
DRBD master. But there are two masters in your cluster, it can not run 
it. Try it again by deleting max-master=2, the default is 1.


Thanks


Is it master-max means: "how many copies of the resource can be promoted 
to master status" ( by Configuration_Explained.pdf  from 
clusterlabs.org)? Whena I'm changeing  role in location to role=master 
crm it shows: "Bad role specified... "


In addition to not starting filesystem, I've change param start-delay 
from default value to 60 of primitive resOCFS2 and now all filesystem 
are mounted properly.

Ok, I've read documentation on novell site, and now group server-www is 
starting properly on the node i want. Unfortunately problem with 
mounting filesystem on the other node sill remains :(

You should use "Master".

Eh? How did that help? In that case there are definitely problems
with some resource agent.

BTW, as far as I know, the ocf:heartbeat:drbd RA doesn't support
multimaster configurations. Perhaps the new ocf:linbit:drbd does.
Best to ask on some drbd forum.

Thanks,

Dejan

I've installed drbd 8.3.2, and changed my config:

   meta clone-max="2" master-max="2" notify="true"

primitive pocztaSystemPlikow ocf:heartbeat:Filesystem \
   params device="/dev/drbd0" directory="/home/data" fstype="ocfs2"

clone kopiaSystemuPlikow pocztaSystemPlikow meta interleave="true"

colocation kopaSystemuPlikow-tylko-z-msPocztaDRBD INFINITY: msPocztaDRBD 
kopiaSystemuPlikow


order pocztaDRBD-przed-systememPlikow mandatory: msPocztaDRBD

but it wasn't help.

This is my drbd.conf:

Re: [Pacemaker] dlm in debian?

[cu...@sonet.internetdsl.pl]

If anyone who has debian can do that (build it from sources)?

Andrew Beekhof pisze:

I doubt it, at least not with the pacemaker bits included.
You'd have to build it from one of the sources rpms in server:ha-clustering

/me makes a note to push the extra changes there up to the dlm Git repo.

Hi,

Does anybody known if the distributed lock manager is somewhere included in
the debian distribution? If yes, what package?
