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

man lsblk

lsblk -o size --nodeps --bytes --noheadings

将为您提供一列数字（以字节为单位），并且--nodeps仅提供sda sdb不包含分区或其他内容的数字。

然后只需将该单列数字相加，然后根据需要分为 kb、mb、gb、tb

通过验证lsblk -o size,fstype,model,name,serial,uuid

似乎您可以通过比较 TYPE 行中的名称mpath（例如360060e80225273005041527300000007出现四次）来检测多路径磁盘。

因此，您需要的唯一字段lsblk应该是设备的名称、它的大小（以字节为单位）和它的类型；但lsblk -nlb -o name,size,type会混淆disk => mpath关联，因此您必须解析的“几乎默认”输出lsblk，例如使用awk：

lsblk -nb |
awk '
    $6 == "disk"  { disk = $1; size[disk] = $4+0 }
    $6 == "mpath" && seen[$1]++ { delete size[disk] }
    END {
        for (disk in size)
            bytes += size[disk]
        gibibytes = bytes / 1024^3
        printf("%.03f%s\n", \
            (gibibytes >= 1024 ? gibibytes / 1024 : gibibytes), \
            (gibibytes >= 1024 ? "T" : "G") \
        )
    }
'

鉴于您的示例输入，输出应该是3.770TiB

补充一下：

您lsblk可能能够使用-J选项输出 JSON。在这种情况下，使用解析和实现逻辑将更加可靠jq。
