[gpfsug-discuss] CES - suspend a node and don't start smb/nfs at mmstartup/boot

[Billich Heinrich Rainer (PSI)]

Hello,

how can I prevent smb, ctdb, nfs (and object) to start when I reboot the node or restart gpfs on a suspended ces node?  Being able to do this would make updates much easier

With

     # mmces node suspend –stop

I can move all IPs to other CES nodes and stop all CES services, what also releases the ces-shared-root-directory and allows to unmount the underlying filesystem.
But after a reboot/restart only the IPs stay on the on the other nodes, the CES services start up. Hm, sometimes I would very much prefer the services to stay down as long as the nodes is suspended and to keep the node out of the CES cluster as much as possible.

I did not try rough things like just renaming smbd, this seems likely to create unwanted issues.

Thank you,

Cheers,

Heiner Billich

Hi Vasily,
I will be at Kubecon with colleagues from Tower Research Capital (and at SC). We have a few hundred nodes across several Kubernetes clusters, most of them mounting Scale from the host.

Folks,   Please let me know if anyone is attending KubeCon'18 in Seattle this December (via private e-mail). We will be there and would like to meet in person with people that already use or consider using Kubernetes/Swarm/Mesos with Scale. The goal is to share experiences, problems, visions.   P.S. If you are not attending KubeCon, but are interested in the topic, shoot me an e-mail anyway.   Best, -- Vasily Tarasov, Research Staff Member, Storage Systems Research, IBM Research - Almaden
