[gpfsug-discuss] number of SMBD processes

[Ouwehand, JJ]

Hello,

Since we use new "IBM Spectrum Scale SMB CES" nodes, we see that that the number of SMBD processes has increased significantly from ~ 4,000 to ~ 7,500. We also see that the SMBD processes are not closed.

This is likely because the Samba global-parameter "deadtime" is missing.

------------
https://www.samba.org/samba/docs/using_samba/ch11.html
This global option sets the number of minutes that Samba will wait for an inactive client before closing its session with the Samba server. A client is considered inactive when it has no open files and no data is being sent from it. The default value for this option is 0, which means that Samba never closes any connection, regardless of how long they have been inactive. This can lead to unnecessary consumption of the server's resources by inactive clients. We recommend that you override the default as follows:

[global]
    deadtime = 10

Is this Samba parameter "deadtime" supported by IBM?
