[gpfsug-discuss] Reason for shutdown: Reset old shared segment

[Saula, Oluwasijibomi]

Hey Folks,

I got a strange message one of my HPC cluster nodes that I'm hoping to understand better: "Reason for shutdown: Reset old shared segment"


2019-05-23_11:47:07.328-0500: [I] This node has a valid standard license

2019-05-23_11:47:07.327-0500: [I] Initializing the fast condition variables at 0x555557115300 ...

2019-05-23_11:47:07.328-0500: [I] mmfsd initializing. {Version: 5.0.0.0   Built: Dec 10 2017 16:59:21} ...

2019-05-23_11:47:07.328-0500: [N] mmfsd is shutting down.

2019-05-23_11:47:07.328-0500: [N] Reason for shutdown: Reset old shared segment

Shortly after the GPFS is back up without any intervention:


2019-05-23_11:47:52.685-0500: [N] Remounted gpfs1

2019-05-23_11:47:52.691-0500: [N] mmfsd ready

I'm supposing this has to do with memory usage??...
