我有一台装有 SSD RAID1 磁盘的远程服务器。我找不到出错磁盘的序列号。有人能帮忙吗？谢谢！
我收到以下错误信息：
A DegradedArray event had been detected on md device /dev/md/1.
PS /proc/mdstat 文件当前包含以下内容：
Personalities : [raid1] [raid6] [raid5] [raid4] [linear] [multipath] [raid0] [raid10]

答案1
我编写了一个脚本，可以检查阵列和所有磁盘以及磁盘的序列号，以便更容易地找到它们。
该脚本（我称之为我的drive_check.bsh）：
#!/bin/bash
# Check for root
if [ "$EUID" -ne 0 ]; then
echo "Please run $0 as root"
echo ""
echo "example:"
echo "sudo $0"
exit 1
fi
# Check for smartmontools
smartctl -h > /dev/null
case $? in
1) echo "smartmontools is not installed. Please install it with the following command:"
echo ""
echo "sudo apt install smartmontools"
exit 1;;
0) ;;
esac
#Get metadisk details for each array
awk '/: active/ {print $1}' /proc/mdstat | while read drv
do
sudo mdadm -D /dev/$drv
done
echo ""
# Create drive array
drives=( $(smartctl --scan | awk '{print $1}') )
# Loop through array and check each drive
for ((i=0; i < ${#drives[@]}; ++i))
do
model=$(smartctl -a ${drives[$i]} | grep -i "device model:" | awk '{print substr($0,index($0,$3))}')
serial=$(smartctl -a ${drives[$i]} | grep -i "serial number:" | awk '{print $NF}')
result=$(smartctl -H ${drives[$i]} | awk '/overall-health/ {print $NF}')
echo -n "${drives[$i]} Model: $model Serial: $serial SMART: $result"
j=$(echo ${drives[$i]} | cut -d/ -f3); echo -n " Errors: "
grep -i error /var/log/kern.log 2>/dev/null | grep "$j," | wc -l
done
使其成为可执行脚本，然后使用 运行它sudo。
例子：
