如何让 multipathd 停止监视我的磁盘？

  • 772

我正在从单个 nvme 磁盘启动 Ubuntu 服务器 20.04。从几天前开始，多路径一直在向我的系统日志发送这些消息：

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，以确认它监控我的 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>

我尝试了命令：

remove map nvme0n1

但得到消息：失败

所以现在的问题是，我怎样才能让它停止监视我的 nvme 磁盘并发送垃圾邮件系统日志？

server multipath

    看来解决方案是将黑名单添加到文件中，/etc/multipath.conf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向系统日志发送垃圾邮件。
