fence_ifmib with snmp v3

[yoyo1811]

Hi,

i'm new to proxmox. I do a test HA cluster of 4 nodes with a managable switch and use fence_ifmib.
I test it with snmp v2 and it work well. But now i want to use snmp v3 but I can't make it work.

Here is the cluster info :


root@mox4:~# cat /etc/pve/cluster.conf

<?xml version="1.0"?>
<cluster config_version="22" name="cluster1">
  <cman keyfile="/var/lib/pve-cluster/corosync.authkey"/>
  <fencedevices>
    <fencedevice agent="fence_ifmib" ipaddr="10.50.1.120" name="fencesw" snmp_version="3" login="snmpUser" passwd="********" snmp_sec_level="authPriv" snmp_priv_passwd="********" snmp_priv_prot="DES" snmp_auth_prot="SHA" />
  </fencedevices>
  <clusternodes>
    <clusternode name="mox1" nodeid="1" votes="1">
      <fence>
        <method name="fence">
          <device action="off" name="fencesw" port="14"/>
        </method>
      </fence>
    </clusternode>
    <clusternode name="mox2" nodeid="2" votes="1">
      <fence>
        <method name="fence">
          <device action="off" name="fencesw" port="13"/>
        </method>
      </fence>
    </clusternode>
    <clusternode name="mox3" nodeid="3" votes="1">
      <fence>
        <method name="fence">
          <device action="off" name="fencesw" port="12"/>
        </method>
      </fence>
    </clusternode>
    <clusternode name="mox4" nodeid="4" votes="1">
      <fence>
        <method name="fence">
          <device action="off" name="fencesw" port="11"/>
        </method>
      </fence>
    </clusternode>
  </clusternodes>
  <rm>
    <pvevm autostart="1" vmid="100"/>
    <pvevm autostart="1" vmid="101"/>
    <pvevm autostart="1" vmid="102"/>
  </rm>
</cluster>

I try to do :

fence_ifmib -a 10.50.1.120 -d 3 -l snmpUser -p ********* -E anthPriv -b SHA -B DES -P *********** -n 1 -o off

it return :

root@mox4:~# fence_ifmib -a 10.50.1.120 -d 3 -l snmpUser -p ********* -E authPriv -b SHA -B DES -P *********** -n 1 -o off

    cmd += " -%s '%s'"% (item[1], self.quote_for_run(self.options["--" + item[1]]))
KeyError: '--a'

There is already a fix for that in the pve-no-subscription repository. Please test with:

# wget http://download.proxmox.com/debian/...nary-amd64/fence-agents-pve_4.0.0-2_amd64.deb
# dpkg -i fence-agents-pve_4.0.0-2_amd64.deb
