Re: [gpfsug-discuss] tscCmdPortRange question

this parameter is just for administrative commands.. "where" to send the output of a command...and for those admin ports .. so called ephemeral ports... it depends , how much admin commands ( = sessions  = sockets)  you want to run in parallel in my experience.. 10 ports is more than enough we use

[gpfsug-discuss] 100G RoCEE and Spectrum Scale Performance

Hi We are currently running Spectrum Scale over FDR Infiniband. We plan on upgrading to EDR since I have not really encountered documentation saying to abandon the lower-latency advantage found in Infiniband. Our workloads generally benefit from lower latency. It looks like, ignoring GPFS, EDR

Re: [gpfsug-discuss] wondering about outage free protocols upgrades

Rolling code upgrade was never support for SMB for the reasons mention in my other email.   The change in 5.0 is to enforce this restriction on a code level. The SMB service will refuse to start on a protocol node, if an incompatible version is already running on another node. Regards, Christof

[gpfsug-discuss] mmfind performance

Hi All, In the README for the mmfind command it says: mmfind A highly efficient file system traversal tool, designed to serve as a drop-in replacement for the 'find' command as used against GPFS FSes. And: mmfind is expected to be slower than find on file systems with relatively few

Re: [gpfsug-discuss] wondering about outage free protocols upgrades

Hi,   at this point there are no plans to support "node by node" upgrade for SMB.   Some background: The technical reason for this restriction is that the records shared between protocol nodes for the SMB service (ctdb and Samba) are not versioned and no mechanism is in place to handle different

Re: [gpfsug-discuss] wondering about outage free protocols upgrades

Thanks for raising this, I was going to ask. The last I heard it was baked into the 5.0 release of Scale but the release notes are eerily quiet on the matter. Would be good to get some input from IBM on this. Richard Get Outlook for Android

Re: [gpfsug-discuss] Meltdown, Spectre, and impacts on GPFS

Hi Leandro, I think the silence in response to your question says a lot, don’t you? :-O IBM has said (on this list, I believe) that the Meltdown / Spectre patches do not impact GPFS functionality. They’ve been silent as to performance impacts, which can and will be taken various ways. In

Re: [gpfsug-discuss] RDMA data from Zimon

Thanks Eric. No one who is a ZIMon developer has jumped up to contradict this, so I’ll go with it :-) Many thanks. This is helpful to understand where the data is coming from and would be a welcome addition to the documentation. Cheers, Kristy > On Feb 15, 2018, at 9:08 AM, Eric Agar

[gpfsug-discuss] tscCmdPortRange question

We are looking at setting a value for tscCmdPortRange so that we can apply firewalls to a small number of GPFS nodes in one of our clusters. The docs don’t give an indication on the number of ports that are required to be in the range. Could anyone make a suggestion on this? It doesn’t appear

Re: [gpfsug-discuss] Meltdown, Spectre, and impacts on GPFS

Hi, The verification/test work is still ongoing. Hopefully GPFS will publish statement soon. I think it would be available through several channels, such as FAQ. Regards, The Spectrum Scale (GPFS) team
