BerLinux: abril 2016

Guía rápida para la creación de un sistema de archivo distribuido y paralelo basado en Lustre versión 2.2.

Esta es una guia rapida para configurar un sistemas de archivos lustre HOME, el ambiente de maquinas virtuales consiste en 1 servidor MDS, 5 servidores OSSs y 1 cliente para probar el montaje del sistemas de achivos LUSTRE.

Esta es una maqueta que se configura de acuerdo a las actuales características del sistema de almacenamiento masivo LUSTRE del Cluster Xiuhcoatl de CINVESTAV Zacatenco:

· Lustre, versión 2.2

· Sistema operativo CentOS. 6.2

Pasos a considerar para la reconstrucción de LUSTRE (según el Lustre* Software Release 2.x: Operations Manual).

1. Set up your Lustre file system hardware.

See Chapter 5, Determining Hardware Configuration Requirements and Formatting Options - Provides

guidelines for configuring hardware for a Lustre file system including storage, memory, and networking

requirements.

2. Configure storage on Lustre storage devices.

See Chapter 6, Configuring Storage on a Lustre File System - Provides instructions for setting up hardware

RAID on Lustre storage devices.

3. Set up network interface bonding.

See Chapter 7, Setting Up Network Interface Bonding - Describes setting up network interface bonding

to allow multiple network interfaces to be used in parallel to increase bandwidth or redundancy.

4. Install Lustre software.

See Chapter 8, Installing the Lustre Software - Describes preparation steps and a procedure for installing

the Lustre software.

5. Configure Lustre networking (LNET).

See Chapter 9, Configuring Lustre Networking (LNET) - Describes how to configure LNET if the

default configuration is not sufficient. By default, LNET will use the first TCP/IP interface it discovers

on a system. LNET configuration is required if you are using InfiniBand or multiple Ethernet interfaces.

6. Configure the Lustre file system.

See Chapter 10, Configuring a Lustre File System - Provides an example of a simple Lustre configuration

procedure and points to tools for completing more complex configurations

failover.Entorno propuesto:

1. Set up your Lustre file system hardware.

Nota: Se puede tener una combinación de clientes lustre de una versión más actual a la instalada en los servidores MDS y OSS.

5. Configure Lustre networking (LNET).

Tenemos que definir en todos los nodos que interactúan con Lustre la interfaz de red a utilizar para ello, en este caso una interfaz Ethernet / tcp, esto se hace en el archivo: /etc/modprobe.d/lnet.conf

1 – Cliente Lustre

[root@client ~]# cat /etc/modprobe.d/lnet.conf

options lnet networks="tcp0(eth0)"

1 – Servidor MDS

[root@mds1 ~]# uname -a

Linux mds1 2.6.32-220.4.2.el6_lustre.x86_64 #1 SMP Wed Mar 14 13:03:47 PDT 2012 x86_64 x86_64 x86_64 GNU/Linux

[root@mds1 ~]# cat /etc/modprobe.d/lnet.conf

options lnet networks="tcp0(eth0)"

5 – Servidores OSSs

[root@oss1 ~]# uname -a

Linux oss1 2.6.32-220.4.2.el6_lustre.x86_64 #1 SMP Wed Mar 14 13:03:47 PDT 2012 x86_64 x86_64 x86_64 GNU/Linux

[root@oss1 ~]# cat /etc/modprobe.d/lnet.conf

options lnet networks="tcp0(eth0)"

6. Configure the Lustre file system.

Creación de OSTs

En este caso como se hará para 5 OSSs con 9 dispositivos que serán usados como OSTs, un total de 45 dispositivos, se escribió el script make_ost-5.sh, el cual se conecta a todos los OSSs.

[root@mds1 ~]# cat bin/make_ost-5.sh

Montaje del filesystem LUSTRE en el sistema cliente:

[root@client ~]# mount -t lustre 172.17.202.120@tcp0:/lfs-home /home/

Uso del home LUSTRE

NOTA: Es indispensable que las cuentas que se crean el el cluster sean también vistas o conocidas por el servidor MDS para no tener problemas de permisos al momeno de accesar a los homes.

Creación de usuarios en el filesystem de LUSTRE:

[root@client ~]# adduser -g users usuario01

[root@client ~]# adduser -g users usuario02

[root@client ~]# adduser -g users usuario03

Revisión de correcto a los homes:

[root@client ~]# su - usuario01

[usuario01@client ~]$ exit

logout

[root@client ~]# su - usuario02

[usuario02@client ~]$ exit

logout

[root@client ~]# su - usuario03

[usuario03@client ~]$ exit

logout

Lisado de sistemas de archivos montados, el filesystem LUSTRE tiene un tamaño de 27 TBytes.

[root@client ~]# df -h

Deses los sistemas cliente lustre se puede revisar cual es la ocupación de todos y cada unos de los OSTs:
