Hi,
I have a working fencing setup with heartbeat-1:
somehost1:~# grep ^stonith /etc/ha.d/ha.cf
stonith_host * cyclades 172.21.101.79 root 10
So thats a cyclades stonith plugin, the IP adress of the Cyclades Alterpath,
login name for SSH login, and the serial port of the IPDU that should
powercycle the node to be fenced.
Now when I want to configure a stonith plugin in corosync/pacemaker, I can't
set the serial port.
There is simply no such parameter in that resource agent shown in pacemaker:
-------------------------------------------------
crm(live)# ra info cyclades stonith
<!-- no value --> (stonith:cyclades)
Cyclades AlterPath PM series power switches (via TS/ACS/KVM).
Parameters (* denotes required, [] the default):
ipaddr* (string): IP Address
The IP address of the STONITH device
login* (string): Login
The username used for logging in to the STONITH device
stonith-timeout (time, [60s]):
How long to wait for the STONITH action to complete. Overrides the
stonith-timeout cluster property
priority (integer, [0]):
The priority of the stonith resource. The lower the number, the higher the
priority.
Operations' defaults (advisory minimum):
start timeout=60
stop timeout=15
status timeout=60
monitor_0 interval=3600 timeout=60
-------------------------------------------------
So I tried with just:
primitive fencing stonith:cyclades \
params ipaddr="172.21.101.79" login="root" \
op monitor interval="15s" timeout="60s"
But it doesn't work:
Failed actions:
fencing:0_start_0 (node=somenode2, call=6, rc=1, status=complete): unknown
error
fencing:1_start_0 (node=somenode1, call=7, rc=1, status=complete): unknown
error
I find no hint except that "unknown error" in syslog or crm shell. And
pacemaker raised fail count to infinite after AFAIR the second attempt. I did
not find a single hint via Google on how to configure stonith with cyclades for
a corosync / pacemaker setup either.
How should it know which serial port I connected the IPDU too?
Related: Why does pacemaker raise failure count to infinity so quickly? In our
old heartbeat setup heartbeat tried stonithing the other hosts for lots of
attempts and didn't give up that quickly. Well usually it should work on the
first attempt, but with shared storage it can be very dangerous if a cluster
partner takes over resources, when fencing the unresponsive node did not work.
I am using corosync 1.2.1-1~bpo50+1 and pacemaker 1.0.9.1-2~bpo50+1 from
