Hi,
You need to give every cluster parameter to the
fence_bladecenter_snmp, so from sp2 you neet to use " Attributes:
action=off ipaddr=172.30.0.2 port=8 community=test login=snmp8
passwd=soft1234", command to use from sp2 for test your fencing
"fence_bladecenter_snmp -a 172.30.0.2 -l snmp8 -p soft1234 -c test -o
status" and if the status is ok, when you will scheduled down time for
your system, you can try to reboot with "fence_bladecenter_snmp -a
172.30.0.2 -l snmp8 -p soft1234 -c test -o reboot"
2014-08-20 16:22 GMT+02:00 Miha <m...@softnet.si>:
ok, will do that. This will not affect sip2?
sorry for my noob question but I must be careful as this is in production ;)
So, "fence_bladecenter_snmp reboot" right?

sorry,
That was a typo, fixed "try to poweroff sp1 by hand, using the
fence_bladecenter_snmp in your shell"
2014-08-19 11:17 GMT+02:00 Miha <m...@softnet.si>:
hi,
what do you mean by "by had of powweroff sp1"? do power off server sip1?
One thing also bothers me. Why on sip2 cluster service is not running if
still virual ip and etc are all properly running?
tnx

Sorry for the short answer, have you tested your cluster fencing ?
can
you show your cluster.conf xml?

Hi emmanuel,

are you sure your cluster fencing is working?

Hi,
I noticed today that I am having some problem with cluster. I
noticed
the
master server is offilne but still virutal ip is assigned to
it
and
all
services are running properly (for production).
If I do this I am getting this notifications:
[root@sip2 cluster]# pcs status
Error: cluster is not currently running on this node
[root@sip2 cluster]# /etc/init.d/corosync status
corosync dead but pid file exists
[root@sip2 cluster]# pcs status
Error: cluster is not currently running on this node
[root@sip2 cluster]#
[root@sip2 cluster]#
[root@sip2 cluster]# tailf fenced.log
Aug 14 13:34:25 fenced cman_get_cluster error -1 112
The main thing is what to do now? Do "pcs start" and hope for
the
best
or
what?
I have pasted log in pastebin: http://pastebin.com/SUp2GcmN
tnx!
miha
