Hi,
I have a 2 node cluster using cman and pacemaker. It was working great
with meatware, so i decided to get myself an AP7920 hardware fencing
device, however i can't seem to get it working from pacemaker using
apcmastersnmp.
(Both apcmaster and external/rackpdu do not work for me. apcmaster has
some telnet string identification problem and can't connect. rackpdu has
some parsing problems, device list is returned by the device (with
errors), but only the first port can be controlled).
Calling stonith itself seems to work, using 2 different types of parameters:
root@pcp-svr008hatest1:~# stonith -l -t apcmastersnmp -p "192.168.90.9 161
private"
pcp-svr008hatest1
pcp-svr009hatest2
outlet 3
outlet 4
outlet 5
outlet 6
outlet 7
test
root@pcp-svr008hatest1:~# stonith -l -t apcmastersnmp
ipaddr="192.168.90.9" port="161" community="private"
pcp-svr008hatest1
pcp-svr009hatest2
outlet 3
outlet 4
outlet 5
outlet 6
outlet 7
test
root@pcp-svr008hatest1:~# stonith -t apcmastersnmp -p "192.168.90.9 161
private" pcp-svr009hatest2
root@pcp-svr008hatest1:~# stonith -t apcmastersnmp -T reset
ipaddr="192.168.90.9" port="161" community="private" pcp-svr009hatest2
(Port resets confirmed both visually and by the ap7920 webgui).
If i configure pacemaker without any pcmk_host parameters:
primitive st_apcmastersnmp stonith:apcmastersnmp \
params community="private" port="161" ipaddr="192.168.90.9"
clone cl_st_apcmastersnmp st_apcmastersnmp
i get the following errors:
Nov 14 16:07:51 pcp-svr008hatest1 stonith: [16045]: ERROR: Could not list
hosts for apcmaster.
Nov 14 16:31:34 pcp-svr008hatest1 stonith-ng: [1659]: info:
can_fence_host_with_device: st_apcmastersnmp:1 can not fence
pcp-svr009hatest2: dynamic-list
I found somewhere to "make sure your device works with -l", but -l works
fine with my device.
If i configure pacmaker with some pcmk_host parameters:
primitive st_apcmastersnmp stonith:apcmastersnmp \
params community="private" port="161" ipaddr="192.168.90.9" \
pcmk_host_check="static-list" \
pcmk_host_list="pcp-svr008hatest1 pcp-svr009hatest2"
clone cl_st_apcmastersnmp st_apcmastersnmp
I get the following error:
Nov 14 16:37:12 pcp-svr008hatest1 stonith-ng: [1659]: info:

I have upgraded to pacemaker 1.1.6, cluster-glue 1.0.8, libstonith1 1.0.8,
libstonithd 1.1.6 without any result.
Am i doing something wrong/missing something, or is something just bugged
somewhere?
