Instalação do dcache nos Thors SUN X4540

Description

Cabeamento dos Thors

Endereços IP e hostnames

Qual o endereço inicial do Thor ???

Acesse o console serial para configurar o IP

login e senha (dãããã)

cd /SP/network
ls
set pendingipaddress=192.168.2.161
set pendinggateway=192.168.2.150
set commit pending=true

Fisicamente os Thor estão ordenados de baixo para cima, logo, o 1o thor de baixo é o No 1.

Kickstart

/tftpboot/pxelinux.cfg

thor-install

[allan@spserv01 pxelinux.cfg]$ cat thor-install default CentOS-5.4-install/vmlinuz append initrd=CentOS-5.4-install/initrd.img method=http://200.145.46.3/CentOS ks=http://200.145.46.3/thor_sprace.ks ksdevice=eth1

C0A801A1 C0A801A2 C0A801A3

192.168.1.161 = C0A801A1 192.168.1.162 = C0A801A2 192.168.1.163 = C0A801A3

CentOS-5.4-install

o ks utilizado para os thor está em http://200.145.46.3/thor_sprace.ks

Criação dos RAIDs de dados

• Criar o layout básico dos discos

echo "
n
p
2


t
2
fd
w
" > fdisk.expect

• Executar o fdisk:

for i in a b c d e f g h i j k l m n o p q r s t u v w x y z;do fdisk \
/dev/sd$i < fdisk.expect; done

for i in a b c d e f g h i j k l m n o p q r s t u v w x y z;do fdisk \
/dev/sda$i < fdisk.expect; done

• Depois de criar as partições devemos reiniciar a máquina

reboot

• Criar os RAIDs

Benchmarking

rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-3.noarch.rpm

yum install  xfsprogs bonnie++ 

mkfs.xfs /dev/md10 

mount /dev/md10 /mnt 
mkdir teste
chown allan.allan teste
cd teste/
bonnie++ -f -n 0 -u 7833 -s 131072:131072

O 7833 é o gid para allan

Alguns comandos mdam:

mdadm --stop /dev/md10 para desmontar o raid ( antes, desmontar o ponto de montagem)

* Test A: Single disk

• • no RAID

• Test B: RAID5 (6 disks)
  • One disk from each controller

• Test C: RAID50 (48 disks)
  • A single RAID 0 with 8 RAID5, each one with 6 disks

mdadm --create /dev/md20 --force --chunk=512 --level=0 --raid-devices=8 --spare-devices=0 /dev/dm10 /dev/md11 /dev/md12 /dev/md13 /dev/dm14 /dev/md15 /dev/dm16 /dev/md17

• Test D: RAID0 (6 disks)
  • One disk from each controller

• Test E: RAID0 (24 disks)
  • 4 disks from each controller

• Test F: RAID0 (48 disks)
  • all disks

mdadm --create /dev/md10 --force --chunk=128 -e 1 --level=0 --raid-devices=48 /dev/sda2 /dev/sdaa2 /dev/sdab2 /dev/sdac2 /dev/sdad2 /dev/sdae2 /dev/sdaf2 /dev/sdag2 /dev/sdah2 /dev/sdai2 /dev/sdaj2 /dev/sdak2 /dev/sdal2 /dev/sdam2 /dev/sdan2 /dev/sdao2 /dev/sdap2 /dev/sdaq2 /dev/sdar2 /dev/sdas2 /dev/sdat2 /dev/sdau2 /dev/sdav2 /dev/sdb2 /dev/sdc2 /dev/sdd2 /dev/sde2 /dev/sdf2 /dev/sdg2 /dev/sdh2 /dev/sdi2 /dev/sdj2 /dev/sdk2 /dev/sdl2 /dev/sdm2 /dev/sdn2 /dev/sdo2 /dev/sdp2 /dev/sdq2 /dev/sdr2 /dev/sds2 /dev/sdt2 /dev/sdu2 /dev/sdv2 /dev/sdw2 /dev/sdx2 /dev/sdy2 /dev/sdz2
