we faced issue about # of RDMA.
One of NSD servers has issue like
- waiting for RDMA read DTO completion
- waiting for RDMA write DTO completion
- waiting for conn rdmas < conn maxrdmas
Attached is the output of mmfsadm dump waiters when we decided to shutdown GPFS on that NSD server.
Does anyone know the means of above messages? especially "read DTO completeion", "write DTO completion"?
This FS worked fine after we shutdown GPFS on that NSD servers.
Is this imply any issues on IB fablic??
