Yes I read this document and found it very informative.

I don't think I'll be able to detect Asterisk failures automatically so
basically I'll rely on a manual processes to either move from one server to
the other or to sync configs (in fact, I'll keep both configs as
independant as possible to avoid one machine's config to corrupt the other).

Re: [asterisk-users] Asterisk HA with heartbeat and systemd

2015-10-20 Thread Olivier 
My machines have both a /usr/lib/ocf/resource.d/heartbeat/asterisk file
(from resource-agents package, it seems).
If I'm not mistaken, this file is not run when asterisk is started/stopped
by hb_standby/hb_takeover commands (I added a touch /tmp/foobar line in
/usr/lib/ocf/resource.d/heartbeat/asterisk to check this).

How does this script compare with rc.debian.asterisk that can be found in
contrib/init.d directory ?
Is this file maintained by Asterisk community and closely following
Asterisk evolution or is it rather independant from Asterisk development
team ?
What would you recommend on this subject ?

If you’re still in the planning stage, there’s a lot more to think about.  Your 
Asterisk failure detection will be very simplistic (is the process dead).  
Synchronization of data – without risking synchronization of corrupt data to a 
peer.  Prevent a deteriorating/failing peer corruption from corrupted the other 
peer (i.e. now shared resources).  Awareness of upstream (e.g.: route/network) 
failures making the peer unavailable – and how to detect that.  Etc. etc.

 

Here’s a good checklist of things to consider in your design:  
http://www.voip-info.org/wiki/view/Asterisk+High+Availability+Design

 

If you are building a small/home office HA then the free version of commercial 
tools may be the way to go.  If have a $0 budget but for a larger installation, 
use the design guide above to help figure out which compromises to make.  
(Heartbeat / Linux HA is better than nothing).

[asterisk-users] Asterisk HA with heartbeat and systemd

2015-10-19 Thread Olivier 
Hello,

I'm setting up an active-passive Asterisk solution on Debian Jessie
platforms.
I'm using heartbeat package.

As I'm not yet familiar with either systemd or heartbeat, I've got a couple
of questions:

1. At the moment, I'm using /usr/share/heartbeat/hb_standby or
/usr/share/heartbeat/hb_takeover scripts to both :
- allocate "floating" IP addresses to active server
- start/stop asterisk daemon.

Is this appropriate ? What would you recommand instead ?


2. My /etc/ha.d/haresources file contains:
machine1 192.168.1.3 asterisk

With this, I can see that asterisk daemon is correctly started and stopped
when hb_standby/hb_takeover commands are typed but "service
asterisk,status" is a bit misleading with:

service asterisk status
● asterisk.service - LSB: Asterisk PBX
   Loaded: loaded (/etc/init.d/asterisk)
   Active: active (exited) since lun. 2015-10-19 18:02:58 CEST; 41min ago
  Process: 19576 ExecStop=/etc/init.d/asterisk stop (code=exited,
status=0/SUCCESS)
  Process: 19583 ExecStart=/etc/init.d/asterisk start (code=exited,
status=0/SUCCESS)

How can I best improve this and configure heartbeat to use "service
asterisk start/stop" ?

Regards
