BerLinux: agosto 2016

Creación de dos sistemas LUSTRE, usando el mismo nodo MDS.

En una publicación previa: http://unberam.blogspot.mx/2016/04/guia-rapida-de-una-instalacion-simple.html, ya describimos el entorno de configuración:

1 Cliente Lustre

1 Nodo MGS/MDS

· Tres dispositivos de bloque, uno para el OS y dos para MDTs

5 Nodos OSS

· Diez dispositivos de bloque, uno para el OS y nueve para OSTs

La configuración que ahora se propone consiste en crear dos sistemas de archivos Lustre, lfs-home y scratch, en el nodo MGS/MDS, sobre un dispositivo se creara el mgs que se compartirá para los mdts que se crearan, correspondientes a los filesystems mencionados, de los 9 OSTs presentes por cada nodo OSS, 6 se usaran para lfs-home y, 3 para scratch.

Configure the Lustre file system.

Creación de los filesystems lustre: lfs-home y scratch

Creación del MGS y el MDT para el lfs-home, en el Servidor MDS

[root@mds1 ~]# mkfs.lustre --fsname=lfs-home --mgs --mdt --index=0 /dev/sdb

Creacion de OSTs

Para garantizar la utilización de todos los OSTs, la indexación se hace de manera horizontal, de entre todos los OSS, tanto de lustre que se usara para home, así como para el lustre que se usara para scratch.

Se escribieron dos scripts para realizar la creación automatizada de los OSTs para lfs-home, y para scratch:

Script para crear los OSTs para el lfs-home: make_ost-lfs-home.sh

#!/bin/bash

Para montar los OSTs se creó una estructura de directorios, en cada OSS:

/lfs-home/

|-- ost0

|-- ost10

|-- ost15

|-- ost20

|-- ost25

`-- ost5

/lfs-scratch/

|-- ost0

|-- ost10

`-- ost5

Se eligió para el ejercicio, realizar un control centralizado de montaje y desmantaje de los OSTs, así que se escribieron los scripts: ost-mount-lfs-home.sh y ost-mount-lfs-scratch.sh, para montar los OSTs de lsf-home y scratch, en los OSS respectivos:
