如何找出 iscsiadm 命令来删除磁盘

例如我有以下磁盘：

[root@xxx-xxxx]# lsblk

如何知道我应该运行哪个命令来删除 /dev/sdk？

我知道命令是

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

但是如何知道使用哪一个iqn和IP来删除呢/dev/sdk？

是否有命令可以检查所有磁盘的总大小（总和）？我们只需要磁盘大小，不包括多路径路径和分区大小，以避免冗余和错误大小（在这种情况下，只有 sda、sdb 等的大小，没有分区 sda1、sda2 等，也没有像 360060e80225273005041527300002000 和 360060e80225273005041527300002000p1 等路径）。

例如，我的服务器只有 3 个 6GB 的磁盘

[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

但lsblks报告6GB 36次

更新：

我尝试了以下脚本，但大小不对

# 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"
fi

当 set -x 打开时如何隐藏变量值

5

我需要在脚本中使用 set -x 来显示日志中执行的命令

但有一个变量是密码，因此该密码显示在计划文本中

有没有办法只隐藏一个变量？

IE：

脚本：

pas=test123

set -x
mysql -uroot -p$pas

输出：

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

我想test123从输出中删除。

编辑：谢谢 BowlOfRed，我正在使用：

rsync -azvp --progress --ignore-existing

现在我在答案中使用 as 并且它有效。

rsync -azp --info=name,progress --ignore-existing

我在udev中做了这个配置：

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

之后，我添加了其他磁盘，新磁盘变成了旧/dev/sde磁盘，因此上面的 udev 规则变得错误，因为名称已更改为. 如何确保正确的磁盘？有其他的身份证吗？我试过类似的东西，但由于没有分区，它不会返回任何 id。/dev/sde/dev/sdfsdesdfblkid

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

当有 iscsi 磁盘时，我会寻找类似的东西，我们可以使用 iscsi id 来做到这一点：

多路径 - /dev/mapper/mpathxx 和 /dev/mapper/mpathxx1 之间有什么区别？

对于每个多路径磁盘标签，/dev/mapper我最后都有另一个带有 1 的标签。他们是一样的吗？有什么关系吗？

例如：

/dev/mapper/mpathaj和/dev/mapper/mpathaj1 或 /dev/mapper/mpathai和/dev/mapper/mpathai1

当我发出命令od --read-bytes=128 --format=c /dev/mapper/mpathai时，磁盘看起来很干净：

[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

但最后 1 的另一个显示一些行：

[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

   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

这发生在每个磁盘上。一个是干净的，另一个没有。

而且，我问它的原因是：我可以失去一个（mpathaj）而不会失去另一个（mpathaj1）吗？我已经看到他们指向不同的/dev/dm-xx.

即：/dev/mapper/mpathaj是/dev/dm-18和/dev/mapper/mpathaj1是/dev/dm-19
