[Linux-HA] DRBD and automatic sync

2012-08-03 Thread Elvis Altherr

Hello together

On my gentoo  servers (2 Node Cluster with kernel 3.x) i use heartbeat 
3.0.5 and DRBD 8.4.0 for block replication between the two machines 
which served apache, mysql and samba fileservices

Everything works fine, except the automatic sync between the two drives 
wich are both primarys

What did i wrong?


conf files see below

drbd.conf

resource r0 {
   # protocol to use; C is the the safest variant
 net {
 allow-two-primaries;
 }

startup {
become-primary-on both;

# timeout (in seconds) for the connection on startup
#after detection of data inconsistencies (degraded mode)

}

# maximum bandwidth to use for this resource

[Linux-HA] Heartbeat Error

2012-08-03 Thread Yount, William D

I am using pacemaker and corosync. For some reason I keep getting this error in 
my messages log:

ERROR: Cannot chdir to [/var/lib/heartbeat/cores/root]: No such file or 
directory

Should I not worry about that since I am using corosync and not heartbeat

Re: [Linux-HA] Heartbeat Error [Solved]

2012-08-03 Thread Yount, William D

I was able to fix the error by creating the directory manually. 
/var/lib/heartbeat/cores was already there, I just added root.

Kind of an odd problem though.

Hi!

We also have OpenAIS/pacemaker here, but I see:
stonith-ng: [20979]: info: crm_log_init_worker: Changed active directory to 
/var/lib/heartbeat/cores/root

So maybe just create that directory ;-)

Re: [Linux-HA] Manual Resource Migration/Move

2012-08-03 Thread Tobias Brunner

Hi list,

Thanks for the input so far, here are new findings.

  meta master-max=1 master-node-max=1 clone-max=2
  clone-node-max=1 notify=true target-role=Master 
  location location-groupMysql-on-node1 groupMysql inf: halab3
 
 So you have a mandatory location constraint saying
   run this thing only on halab3
 

You're right, that's not what I want.

 Remove the inf: halab3, or replace it with some not infinite score.

Ok, that's done! Now here is a crm configure show from another cluster on 
which crm resource move groupApache nodeha2 doesn't work (same configuration 
as halab3):

[Linux-HA] environment variables and stonith

2012-08-03 Thread Darin Perusich

Hello All,

Is it possible to set/pass an environment variable so a stonith device
will inherit it, specifically external/vcenter in this case? The issue
I'm running into is the vcenter I'm connecting to is using self-signed
certificates, which I get around by setting the environment variable
PERL_LWP_SSL_VERIFY_HOSTNAME=0, but the processes do not inherit this
variable when the machines are rebooted.

I know I can hack VICommon.pm and add
$ENV{PERL_LWP_SSL_VERIFY_HOSTNAME} = 0; but that's unclean and
something I really don't want to do. I've started looking at modifying
the vcenter module to add this param but that's more of a long term
solution and doesn't address my immediate needs.

I'm running on OpenSUSE 12.1 and PERL_LWP_SSL_VERIFY_HOSTNAME=0 is
being passed into the openais init script, which start corosync, by
way of /etc/sysconfig/pacemaker but that doesn't matter.

Thanks!

 yes.. woud i better use GFS2 or OFCS (which both dosen't work under

 Or which is the best file system porpouse for my case?

If you're on 3.x why not use ceph and ditch the whole drbd/pacemaker
thing altogether? It can't be worse than ext3 on dual-primary drbd using
haresources mode.

Hi Dimitri

Well i'll give a look  thanks for the suggestion

i recently bought a very useful book about this theme (Clusterbuild HA 
on Linux from Michael Schwarzkopff) maybe this will guide me for a 
useful solution
