Add NAS Appliance¶
This section describes the required steps in Rocks to add a new NAS system appliance.
# The first part will configure an IB interface for the NAS
rocks add host nas-1 membership='NAS Appliance' cpus=48 rack=0 rank=1
rocks add host interface nas-1 iface=ib1
rocks set host interface subnet nas-1 iface=ib1 subnet=mpi-nfs
rocks set host interface ip nas-1 iface=ib1 ip=<nas ip>
rocks set host interface mac nas-1 iface=ib1 mac=<mac>
rocks set host interface module nas-1 iface=ib1 module=ib_ipoib
rocks set host attr nas-1 arch x86_64
rocks set host attr nas-1 os linux
rocks set host attr nas-1 managed false
rocks set host attr nas-1 kickstartable false
rocks set host installaction nas-1 action=os
rocks set host boot nas-1 action=os
rocks set attr Info_HomeDirSrv nas-1.mpi-nfs
rocks sync config
# This second part will configure a second interface for the NAS (admin network)
rocks add network admin subnet=<subnet ip> netmask=<mask> dnszone=<domain> mtu=1500 servedns=False
rocks add host interface nas-1 iface=em3
rocks set host interface mac nas-1 iface=em3 mac=<mac>
rocks set host interface ip nas-1 iface=em3 ip=<ip>
rocks set host interface subnet nas-1 iface=em3 subnet=admin
Troubleshooting¶
This section is intended to be a quick reference for the most common errors produced in Rocks and its solutions made by us.
Infiniband¶
- Issue 1: Permanent connected-mode
If we add the
CONNECTED_MODE=yes
parameter to ib0 interface configuration, it works well but this parameter is removed when the commandrocks sync network
is run, therefore the connected mode is disabled.- Solution
- There is an official way to enable the connected mode using the parameter
SETIPOIBCM=yes
on (/etc/infiniband/openib.conf) file if you are using Mellanox OFED.
