Como descobrir o comando iscsiadm para remover um disco

Por exemplo, tenho os seguintes discos:

[root@xxx-xxxx]# lsblk

Como saber qual comando devo executar para remover /dev/sdk?

sudo iscsiadm -m node -T iqn.2015-12.com.oracleiaas:xxxxxxxxxxx-xxxxxxxxxx-p 169.xxx.x.xx:3260 -u
sudo iscsiadm -m node -o delete -T iqn.2015-12.com.oracleiaas:xxxxxxxxxx-xxxx-xxxx-xxxx-xxxxxx-p 169.xxx.x.xx:3260

Existe um comando para verificar o tamanho total (soma) de todos os discos? Queremos apenas os tamanhos dos discos, excluindo os caminhos multipath e o tamanho das partições, para evitar redundância e tamanho errado (neste caso, apenas o tamanho de sda, sdb etc..., sem as partições sda1,sda2 etc... e sem os caminhos como 360060e80225273005041527300002000 e 360060e80225273005041527300002000p1 etc...).

Por exemplo, no meu servidor só tenho 3 discos de 6GBs

[root@xxxxxx~]# multipath -ll|grep '6.0G'
size=6.0G features='0' hwhandler='0' wp=rw
size=6.0G features='0' hwhandler='0' wp=rw
size=6.0G features='0' hwhandler='0' wp=rw

mas lsblksrelatar 6 GB 36 vezes

Atualizar:

Eu tentei o seguinte script, mas o tamanho está errado

# Lista todos os discos com TYPE "disk" e calcula o armazenamento total

total_storage=$(lsblk -b -o NAME,SIZE,TYPE,MOUNTPOINT | awk '$3 == "disk" {total += $2} END {print total / (1024^3)}')
 
# Converte o total para T se for maior que 1000G e limita a 3 casas decimais
if (( $(echo "$total_storage > 1000" | bc -l) )); then
    total_storage_tb=$(echo "scale=3; $total_storage / 1024" | bc -l)
    echo "Armazenamento total de discos: ${total_storage_tb}T"
else
    total_storage_gb=$(printf "%.3f" "$total_storage")
    echo "Armazenamento total de discos: ${total_storage_gb}G"

Como ocultar um valor de variável quando set -x está ativado

5

Preciso usar set -x no meu script para mostrar os comandos executados no meu log

mas existe uma variável que é uma senha, então essa senha é mostrada no texto do plano

Existe uma maneira de ocultar apenas uma variável?

ou seja:

roteiro:

pas=test123

set -x
mysql -uroot -p$pas

a saída:

[root@server1]# ./teste.sh
++ mysql -uroot -ptest123

Quero remover test123da saída.

Agora estou usando como na resposta e está funcionando.

Como aplicar a regra udev a um disco local não particionado?

Eu fiz esta configuração no udev:

KERNEL=="sdd", SYMLINK+="QUORUML", OWNER="test", GROUP="gtest", MODE="0660"
KERNEL=="sde", SYMLINK+="QUORUMR", OWNER="test", GROUP="gtest", MODE="0660"

e depois, adicionei outro disco e o novo disco se tornou o /dev/sdee o antigo /dev/sdese tornou /dev/sdf, então a regra do udev acima ficou errada, pois o nome de sdemudou para sdf. Como posso garantir o disco correto? existe algum outro id? Eu tentei algo como blkid, mas como não há partição, ele não retorna nenhum id.

[root@dbnode1 rules.d]# blkid /dev/sdd
[root@dbnode1 rules.d]#

Eu procuro algo como quando há discos iscsi, podemos fazer isso usando o id iscsi:

KERNEL=="sd?1", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$parent", RESULT=="360014054187384e668f45e58d036f19a", SYMLINK+="disk4", OWNER="xxxx", GROUP="xxxx", MODE="0660"

Multipath - quais são as diferenças entre /dev/mapper/mpathxx e /dev/mapper/mpathxx1?

0

Para cada rótulo de disco multipath /dev/mappereu tenho outro com 1 no final. Eles são os mesmos? existe alguma relação?

Por exemplo:

/dev/mapper/mpathaje /dev/mapper/mpathaj1 ou /dev/mapper/mpathaie/dev/mapper/mpathai1

quando eu emito o comando od --read-bytes=128 --format=c /dev/mapper/mpathai, o disco parece limpo:

[root@server02 ~]# od --read-bytes=128 --format=c /dev/mapper/mpathai
0000000  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0
*
0000200

Mas o outro com 1 no final mostra algumas linhas:

[root@server02 ~]# od --read-bytes=128 --format=c /dev/mapper/mpathai1
0000000 001 202 001 001  \0  \0  \0  \0 003  \0  \0 200 220   .   5 213

0000120   3  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0
   some characters I needed to remove to don't show costumer content.
0000160  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0
0000200

Isso acontece com todos os discos. Um é limpo e o outro não.

E, a razão pela qual estou perguntando: Posso perder um (mpathaj) sem perder o outro (mpathaj1)? Eu vi que eles apontam para diferentes /dev/dm-xx.

ou seja: /dev/mapper/mpathajé /dev/dm-18e /dev/mapper/mpathaj1é/dev/dm-19
