如何使多路径停止监视磁盘？

Question

我从一个nvme磁盘启动Ubuntu服务器20.04。从几天前开始，多路径就一直在我的syslog中发送以下消息：

Jun 11 20:10:14 xb multipath: nvme0n1: failed to get udev uid: Invalid argument
Jun 11 20:10:14 xb multipath: nvme0n1: uid = eui.0000000001000000e4d25c7f117c5001 (sysfs)
Jun 11 20:10:17 xb multipath: nvme0n1: failed to get udev uid: Invalid argument
Jun 11 20:10:17 xb multipath: nvme0n1: uid = eui.0000000001000000e4d25c7f117c5001 (sysfs)
Jun 11 20:10:20 xb multipath: nvme0n1: failed to get udev uid: Invalid argument
Jun 11 20:10:20 xb multipath: nvme0n1: uid = eui.0000000001000000e4d25c7f117c5001 (sysfs)
Jun 11 20:11:34 xb multipath: nvme0n1: failed to get udev uid: Invalid argument
Jun 11 20:11:34 xb multipath: nvme0n1: uid = eui.0000000001000000e4d25c7f117c5001 (sysfs)
Jun 11 20:11:37 xb multipath: nvme0n1: failed to get udev uid: Invalid argument
Jun 11 20:11:37 xb multipath: nvme0n1: uid = eui.0000000001000000e4d25c7f117c5001 (sysfs)

我可以获得以下设备列表以确认它监视我的nvme磁盘：

multipathd> show devices
available block devices:
loop1 devnode blacklisted, unmonitored
nvme0n1 devnode whitelisted, monitored
loop6 devnode blacklisted, unmonitored
loop4 devnode blacklisted, unmonitored
loop2 devnode blacklisted, unmonitored
loop0 devnode blacklisted, unmonitored
loop7 devnode blacklisted, unmonitored
loop5 devnode blacklisted, unmonitored
loop3 devnode blacklisted, unmonitored
multipathd> 

我试过命令：

remove map nvme0n1

但是得到了这样的信息:失败

所以现在的问题是，我如何才能让它停止监视我的nvme磁盘和垃圾邮件系统日志？

Answer 1

解决方案似乎是向文件/etc/multipath.conf添加黑名单，如下所示：

defaults {
    user_friendly_names yes
} 
blacklist {
    devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st|sd|mmc|nvme)[a-z0-9]*"
}

这有效地阻止了多路径垃圾处理syslog。
