将 106 个 JBOD 盘柜（通过 HBA 卡的 106 个 18TB 驱动器）连接到 Debian Bullseye 服务器时，我收到了针对 106 个驱动器中任意一个的每条路径的以下垃圾邮件。
这使得重新启动需要花费大量时间。
例子：
WARNING: Device /dev/sdcf not initialized in udev database even after waiting 10000000 microseconds
是什么原因造成的？我似乎无法弄清楚。
答案1
该问题与 systemd/udev 有关。
解决方案是从向后移植安装 systemd 和 udev 版本 250.3-2~bpo11+1 或更高版本并重新启动，这对我有用。
答案2
我的目标也有同样的问题。但是，在带有 systemd 251.5-1 的 Debian 11.5 上，我不可能改变这种行为。
在我的 LVM 日志中，始终遵循以下消息
警告：即使等待 10000000 微秒，设备 /dev/sda17 也未在 udev 数据库中初始化。
对我来说，解决方案是通过设置来改变 LVM 的行为udev_sync和udev_规则为 0 而不是 Debian 标准值 1。
请在下面找到我的配置。
