Hi wenxia...@126.com,
What is your full DNS domain name, and is /etc/resolv.conf consistent with
your DNS? It seems to me that your DNS server is named "slurmctld-source":
NS slurmctld-source.
so you may have an error in the DNS setup.
The DNS SRV record can be looked up by:
$ host -t SRV _slurmctld._tcp.<your-DNS-domain>
This also works using the DNS search domains specified in /etc/resolv.conf:
$ host -t SRV _slurmctld._tcp
In our cluster both of the above commands work correctly when executed on
the cluster nodes.
I hope this helps.
/Ole

Hi list,
I configured the DNS as below, foundthe Slurm could not find the IP of ctld.
add below to the file :/etc/named.conf
zone "slurmctld-source" IN {
type master;
file "slurmctld-source.zone";
};
and add below file /var/named/slurmctld-source.zone:
$TTL 1D
@ IN SOA . . (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
NS slurmctld-source.
ns A 10.6.6.161
_slurmctld._tcp 3600 IN SRV 10 0 6817 10.6.6.162.
3600 IN SRV 0 0 6817 10.6.6.161.
The configuration can only use the below command :
host -t SRV _slurmctld._tcp.slurmctld-source
in Slurm code, the logic like use below command to get ctld info, it failed:
host -t SRV _slurmctld._tcp
how can I change the configuration to get Ctld info by using the short
query info?
