InfiniBand config and route in redhat
0
I have a system (HPC) have
1 headnode (192.168.2.2)
10 node and (192.168.245-254)
1 NFS server (192.168.2.244).
I have a issue
My headnode can't ping to NFS server but from NFS server I can ping to headnode.
I already disable firewall in 2 PC but it still didn't work.
