[gpfsug-discuss] Spectrum scale sending cluster traffic across the management network

[Jon Edwards]

Hi All,

Just getting started with spectrum scale,


Just wondering if anyone has come across the issue where when doing a mmcrfs or mmdelfs you get the error

Failed to connect to file system daemon: Connection timed out
mmdelfs: tsdelfs failed.
mmdelfs: Command failed. Examine previous error messages to determine cause.


When viewing the logs in  /var/mmfs/gen/mmfslog on a node other than the one I am running the command on i get:

2017-04-07_14:03:13.354+1000: [N] Filtered log entry: 'connect to node 192.168.0.1:1191' occurred 10 times between 2017-04-07_11:38:19.058+1000 and 2017-04-07_11:54:58.649+1000

192.168.0.0/24  In this case is the management network configured on eth0 of all the nodes.
It is failing because port 1191 is not allowed on this interface.

The dns and hostname for each node resolves to a dedicated cluster network, lets say 10.0.0.0/24 (ETH1)



For some reason when I run the mmcrfs or mmdelfs it tries to talk back over the management network instead of the cluster network which fails to connect due to firewall blocking cluster traffic over management.

Anyone seen this before?

Kind Regards,
