ProxmoxVE ( smartd ) 单独忽略某块硬盘的 SMART 报警

背景#

PVE 的系统盘是三块 NVMe 组的 mirror，其中两块寿命已经到期，但还能正常使用，暂时不打算更换。smartd 每天会发邮件提醒：

1
Device: /dev/nvme3, Critical Warning (0x04): Reliability
2
Device info: SAMSUNG MZ9LQ128HBHQ-000H1, ...

需求是单独屏蔽这块盘的报警，其他盘继续监控。

配置方法#

默认在/etc/smartd.conf中，会检测所有设备

1
DEVICESCAN -d removable -n standby -m root -M exec /usr/share/smartmontools/smartd-runner

感谢Arch手册smartd.conf 要排除其中一块，有两个关键点：

-d ignore 指令可以让 smartd 跳过指定设备。
写在 DEVICESCAN 前面的配置会优先生效。

所以在 DEVICESCAN 上面加一行即可：

1
/dev/nvme3 -d ignore
2
DEVICESCAN -d removable -n standby -m root -M exec /usr/share/smartmontools/smartd-runner

使用smartd -q onecheck 2>&1 | grep -i monitor检查看到/dev/nvme3被排除了就没问题。

1
root@serverhub:~# smartd -q onecheck 2>&1 | grep -i monitor
2
Device: /dev/nvme0, is SMART capable. Adding to "monitor" list.
3
Device: /dev/nvme1, is SMART capable. Adding to "monitor" list.

补充#

大家都知道/dev/nvme3这样的写法是阴间的，因为设备变动导致在开机时重算会生成不同的id，应该使用/dev/disk/by-xxx/xxx的方式。

但是，/dev/disk/by-id/下的设备没有/dev/nvme3然而用/dev/nvme3n1这样带namespace的就不行。

1
root@serverhub:~# ls -l /dev/disk/by-id/
