my cluster, but i'm unable to determine why ibacm is failing<br>
<br>
here's what i did<br>
<br>
ib_acme -A -O<br>
systemctl restart ibacm<br>
<br>
in the /var/log/ibacm file i see<br>
<br>
acm_if_iter_sys: ioctl ifconf error -1<br>
acmp_join_group: qib0 1 pkey 0xffff, sl 0x0, rate 0x3, mtu 0x4<br>
acm_server: started<br>
<br>
but when i try to query the node locally<br>
<br>
ib_acme -d node001 -v -V<br>
<br>
in the log file i see<br>
<br>
acm_svr_resolve_dest: notice - unknown local end point address<br>
<br>
on the console i see<br>
<br>
Service: localhost<br>
Destination: 172.21.80.1<br>
ib_acm_resolve_ip failed: cannot assign requested address<br>
SA verification: failed cannot assign requested address<br>
<br>
the ibacm_addr.cfg contains<br>
node001 qib0 1 default<br>
node001-1 qib0 1 default<br>
<br>
all the nodes in the cluster are configured the exact same way. and<br>
produce the same result when trying to query locally or a remote node<br>
<br>
any thoughts?<br>
