[ClusterLabs] clvmd in rgmanager with self_fence="true"

2016-08-02 Thread Digimer 
Hi all,

  Do to recent issues[1], I want to configure cman/rgmanager to
suicide/self-fence if clvmd fails for some reason. The RHBZ suggested
adding 'self_fence="true"' to the service, but this is not supported by
the 'script' RA.

  I decided to try and use the lvm RA, but despite there being
references to clvmd, it seems to insist on an active/passive setup. When
I start LVM service on the second node, it complains that the LV is
already activated on another node.

  I've been googling trying to find an example implementation of
active/active LVM in rgmanager but have come up frustratingly blank. If
anyone can give me a clue, I would be very grateful. :)

[ClusterLabs] [Announce] clufter v0.59.4 released

2016-08-02 Thread Jan Pokorný 
I am happy to announce that clufter, a tool/library for transforming
and analyzing cluster configuration formats, got its version 0.59.4
tagged and released (incl. signature using my 60BCBB4F5CD7F9EF key):


or alternative (original) location:



The test suite is the same as for 0.59.1 as nothing changed there:

or alternatively:


Changelog highlights for v0.59.4 (also available as a tag message):

- bug fix release straightening recent changes up
- feature extensions:
  . when *2pcscmd commands colorize the output, upcoming booth-related
pcs commands are considered as well
- bug fixes:
  . {ccs,pcs}2pcscmd* would previously exceed a recursion limit due
to not catching the bottom of the recursion properly
  . with *2pcscmd* commands, --dump=cmd-annotate switch would
previously cause troubles as newly introduced Nothing format
lacked "hash" property (which is used to construct reasonably
unique file name to store the intermediate result at individual
phases of the filter-piping process)

* * *

The public repository (notably master and next branches) is currently at

(rather than ).

Official, signed releases can be found at
 or, alternatively, at

(also beware, automatic git archives preserve a "dev structure").

Natively packaged in Fedora (python-clufter, clufter-cli).

Issues & suggestions can be reported at either of (regardless if Fedora)
,
.


Happy clustering/high-availing :)

I *think* it fell behind (fence_ec2, iirc). It might need to be picked
up, updated/tested and then it can be re-added to the official list.

I'm not 100% on this though, so if someone contradicts me, ignore me.

OEL is, shall we say, very similar to RHEL. RHEL doesn't support
OCFS2, so it does not include that RA. It is ironic that OEL doesn't
change that. In any case, you can get the RA from the upstream source:

While looking how we did it, I found something interesting: For groups the RA 
is displayed by crm_mon, but for clones it isn't (prm_O2CB isn't shown 
anywhere):
Like this:
[...]
 Clone Set: cln_O2CB [prm_O2CB]
 Started: [ h02 h06 ]
 Resource Group: grp_rksapT11
 prm_T11_ip_1  (ocf::heartbeat:IPaddr2):   Started h06
 prm_isredir_t11_dp02   (ocf::xola:isredir):Stopped
 prm_isredir_t11_dp03   (ocf::xola:isredir):Stopped
[...]


What we use here is this (crmsh syntax):
primitive prm_O2CB ocf:ocfs2:o2cb \
op start interval=0 timeout=90 \
op stop interval=0 timeout=120 \
op monitor interval=60 timeout=60 \
meta priority=9880
[...]

Regards,
Ulrich

[ClusterLabs] STONITH Fencing for Amazon EC2

2016-08-02 Thread Jason A Ramsey 
I’ve found [oldish] references on the internet to a fencing module for Amazon 
EC2, but it doesn’t seem to be included in any the fencing yum packages for 
CentOS. Is this module not part of the canonical distribution? Is there 
something else I should be looking for?

Re: [ClusterLabs] Bloody Newbie needs help for OCFS2 on pacemaker+corosync+pcs

2016-08-02 Thread thl 
Hello Kyle + all,

No luck at all. Cant get o2cb up at all. Please find details below. Thanks in 
advance for any help.

First I tried to translate your crm syntax to pcs syntax:

primitive p_o2cb lsb:o2cb \
op monitor interval="10" timeout="30" \
op start interval="0" timeout="120" \
op stop interval="0" timeout="120"

  |||
  vvv

# pcs resource create ResO2CB lsb:o2cb \
op monitor interval="10" timeout="30" \
op start interval="0" timeout="120" \
op stop interval="0" timeout="120"

Error: Unable to create resource 'lsb:o2cb', it is not installed on this system 
(use --force to override)


I checked my installation and found this:

# rpm -ql pacemaker | grep o2cb
/usr/share/man/man7/ocf_pacemaker_o2cb.7.gz

According this, I would expect /usr/lib/ocf/resource.d/pacemaker/o2cb but there 
is no such script.

But I succeeded in:

# pcs resource create --force ResO2CB ocf:pacemaker:o2cb \
op monitor interval="10" timeout="30" \
op start interval="0" timeout="120" \
op stop interval="0" timeout="120"

# pcs resource show
...
ResO2CB(ocf::pacemaker:o2cb):  Stopped
...

Trying to debug-start:

# pcs resource debug-start ResO2CB
Error performing operation: Input/output error



# rpm -qi pacemaker
Name: pacemaker
Version : 1.1.13
Release : 10.el7
Architecture: x86_64
Install Date: Sa 23 Jul 2016 15:23:51 CEST

Source RPM  : pacemaker-1.1.13-10.el7.src.rpm
Build Date  : Sa 21 Nov 2015 18:10:40 CET
...

It seems that o2cb script is missing in that RPM. Or did I miss to install any 
package?

Best Regards

Thomas Hluchnik

Subject: [ClusterLabs] Bloody Newbie needs help for OCFS2 on
pacemaker+corosync+pcs

Hello everybody,
I am new to pacemaker (and to this list), trying to understand pacemaker. For 
this I created three virtual hosts in my VirtualBox plus four shared disks, 
attached with each of the three nodes.

I installed Oracle Enterprise Linux 7.1, did a "yum update" and got OEL7.2.
Then I created four OCFS2 devices, working fine on all of my three nodes. They 
are started by systemd, using o2cb.service and ocfs2.service and running fine.

Now I have started with learning pacemaker by "Clusters from Scratch" and 
meanwhile I have a virtual IP and a Webserver, this works fine so far.

Next I want to control my OCFS2 devices by pacemaker, not by systemd. I 
searched the net and found some howtos, but they rely on crmsh instead of pcs. 
Most headaches come from DRBD which I don't understand at all. Why the hell 
does it seem that I need DRBD for running OCFS2?

Is there anybody who can explain me how to get that running (after disabling 
o2cb.service & ocfs2.service):

- create a resource which manages and controls o2cb stack
- create another resource which manages OCFS2 mountpoints
- create constraints for the Web Server (all Apache config / content shall be 
copied to one of the OCFS2 filesystems)

The Web Server shall be dependent from availability of a mounted OCFS2 device. 
If it stops working, the Web Server must switch to a node where that mount 
point is OK.

Thanks in advance for any help

Thomas Hluchnik
